Caching in ASP .NET Core:

Introduction:

Effective data caching techniques are critical to improving the performance of web applications in the modern digital environment, where speed and scalability are critical requirements. The robust caching features of Microsoft’s open-source, cross-platform ASP.NET Core framework can greatly increase the scalability and responsiveness of web applications. We’ll examine the advantages, methods for implementation, and best practices of caching in ASP.NET Core in this article.

 The Advantages of Caching in ASP.NET Core:

Caching stores frequently accessed data temporarily, reducing the need to retrieve it from its original source repeatedly. In ASP.NET Core, caching provides several advantages, including:

  • Enhanced Performance: Caching lowers the latency involved in retrieving data from its original source by keeping frequently accessed data in memory, giving users faster response times.
  • Decreased Database Load: By providing cached data rather than querying the database for each request, caching helps reduce the strain on the database server and increase system scalability.
  • Improved Scalability: ASP.NET Core apps are more responsive and scalable when they use caching to manage more concurrent users and requests without sacrificing performance.

Types of Caching in ASP.NET Core:

Different caching mechanisms that meet different needs and scenarios are supported by ASP.NET Core. Several frequently utilized types of caching include:

  • In-Memory Caching: This technique keeps data in the memory of the application so that it is easily accessible to queries made later. For storing small to medium-sized data sets that are accessed frequently, this kind of caching is appropriate.
  • Distributed Caching: With distributed caching, data that has been cached can be shared between several applications or even between various web farm servers. Support for distributed caching with providers like Redis, SQL Server, or NCache is integrated into ASP.NET Core.
  • Response Caching: This technique allows the entire HTTP response to be cached, including the status codes, HTTP headers, and HTML content that is generated. For content that can be cached at the HTTP level and is static or semi-static, this kind of caching is perfect.

Implementing Caching in ASP.NET Core:

Developers can take the following actions to take advantage of caching in ASP.NET Core:

  • Configure Caching Services: Use the AddMemoryCache() or AddDistributedMemoryCache() methods to register caching services for either distributed or in-memory caching in the dependency injection container of the ASP.NET Core application.
  • Install Caching Middleware: To enable response caching, add caching middleware to the application’s request processing pipeline by either implementing custom middleware for more granular control or by using the UseResponseCaching() method.
  • Decorate Cached Resources: To define caching policies, such as cache duration, cache location, and cache profiles, decorate controller actions or Razor pages with caching attributes like [ResponseCache].

 Best Practices for Caching in ASP.NET Core:

The following best practices should be taken into consideration in order to optimize the advantages of caching while avoiding typical pitfalls:

  • Use Caching Wisely: Only store in cache data that is likely to be frequently retrieved or computed at a high cost. Refrain from over-caching or caching frequently changing volatile data.
  • Track Cache Performance: To guarantee optimal cache performance and avoid memory-related problems, track cache hit rates, eviction rates, and memory usage.
  • Use Cache Invalidation: Use cache expiration policies or manual cache invalidation mechanisms, among other cache invalidation techniques, to guarantee that data in the cache is accurate and current.

 Conclusion:

Caching is a potent method for enhancing ASP.NET Core applications’ responsiveness, scalability, and performance. Developers can greatly lower latency, lessen database load, and improve user experience by utilizing caching mechanisms like in-memory caching, distributed caching, and response caching. To optimize its advantages while averting any potential downsides, caching must be used sparingly and in accordance with best practices. Because caching is a fundamental component of optimization strategies, ASP.NET Core applications can easily scale to meet the demands of contemporary online environments while delivering lightning-fast performance.

Authentication and Authorization in ASP.NET:

Introduction:

ASP.NET includes robust mechanisms for handling authentication and authorization in web applications, ensuring resource security. Authentication is the process of verifying a user’s identity, whereas authorization entails granting or denying access to specific resources based on the authenticated user’s permissions. This article delves into the fundamentals of ASP.NET authentication and authorization, focusing on best practices and key components.

Authentication in ASP.NET:

Forms Authentication:

Forms Authentication in ASP.NET is a mechanism that allows you to authenticate users using their credentials (such as a username and password) via a web form. It entails creating a login page where users enter their credentials, validating those credentials, and issuing an authentication ticket (usually in the form of a cookie) after successful authentication. This authentication ticket is then used to identify the user for future requests.

Here is a step-by-step guide for implementing Forms Authentication in ASP.NET:

Step 1: Configure Authentication in “web.config”: In your web application’s “web.config” file, configure the authentication mode to Forms and specify the login page. “loginUrl” – Specifies the URL of the login page. “timeout” – Sets the expiration time for the authentication ticket in minutes.

Step 2: Create a Login Page: Create a login page where users can enter their credentials. You can use standard HTML controls or ASP.NET controls for the username and password input fields.

Step 3: Authenticate Users: In the code-behind of the login page (Login.aspx.cs), validate the user credentials. If the credentials are valid, issue an authentication ticket using “FormsAuthentication.SetAuthCookie()”.

Step 4: Secure Pages: Use the “Authorize” attribute on pages or controllers that should only be accessible to authenticated users.

With these steps, you can add Forms Authentication to your ASP.NET application. If users attempt to access secured resources without authentication, they will be redirected to the login page, and their authentication ticket will be used to identify them across subsequent requests.

Windows Authentication:

Windows Authentication in ASP.NET is a feature that uses the underlying Windows operating system’s security framework to verify user identity. When the client and server are both a part of the same Windows domain, this authentication technique is frequently used in intranet scenarios. Users that use Windows Authentication don’t need to enter different credentials because they are automatically authenticated using their Windows credentials.

Here is a comprehensive tutorial on configuring Windows Authentication in an ASP.NET application.

Step 1: Configure Authentication in “Web.config”: In your web application’s “web.config” file, set the authentication mode to “Windows” within the <system.web> section. This configuration informs ASP.NET to use Windows Authentication.

Step 2: Set Authorization Rules: Specify authorization rules in the <system.web> section to control access to specific pages or directories. For example, to allow all authenticated users. This configuration allows any authenticated user to access the resources.

Step 3: Enable Windows Authentication in IIS: Ensure that Windows Authentication is enabled in Internet Information Services (IIS):

Open IIS Manager –> Select your site –> In the Features View, double-click “Authentication” –> Enable “Windows Authentication” and disable other authentication methods if not needed.

Step 4: Implement Authorization in Code (Optional): If you need more fine-grained control over authorization, you can use the “WindowsPrincipal” class in your code-behind files.

Step 5: Test the Application: Run your application, and it should automatically prompt users to authenticate using their Windows credentials. The application will then grant or deny access based on the configured authorization rules.

Step 6: Keep in mind that intranet scenarios, in which the application server and users are within the same Windows domain, are optimal for the use of Windows Authentication. Other authentication techniques like Forms Authentication or ASP.NET Core Identity might be more appropriate if users are accessing the application via the internet or from different domains.

Identity Providers and OAuth:

Identity Providers (IdPs) are third-party services that verify users and give applications access to their personal data. Users can use their existing login credentials from these providers to access your application. Examples include Twitter, Microsoft, Facebook, Google, and so on.

OAuth is an open standard for access delegation that supports various flows, including the client credentials flow, implicit flow, and authorization code flow. It is frequently used for token-based authentication. It enables your application to ask an Identity Provider for access tokens on a user’s behalf and receive them.

When a user clicks the “Login with Google” button (or any other provider), your application directs them to the Identity Provider’s login page. After successful authentication, the Identity Provider sends the user back to your application with an authorization code or access token.

Integrating Identity Providers and OAuth into your ASP.NET application (particularly ASP.NET Core) simplifies user authentication, reduces the need for users to create new accounts, and improves the overall user experience. It is critical to adhere to the specific implementation guidelines provided by each Identity Provider with which you intend to integrate, as OAuth flows and configuration requirements may differ.

Authorization in ASP.NET:

Role-Based Authorization:

Role-based authorization in ASP.NET allows you to restrict access to specific parts of your application based on predefined roles. This allows you to specify which users can perform specific actions or access specific resources. Role-based authorization assigns users to one or more roles, and access to specific features or pages is granted based on those roles.

Here’s a guide for implementing role-based authorization in ASP.NET.

Step 1: Define Roles: Roles represent groups of users with similar permissions. You need to define roles in your application, and users will be assigned to these roles. You can define roles programmatically or use a database to store roles.

Step 2: Assign Roles to Users: In your user management system (this could be part of your registration or admin interface), assign roles to users.

Step 3: Configure Role-Based Authorization: In your application, you can use the “[Authorize]” attribute along with the “Roles” property to control access to specific controllers or actions.

Step 4: Check Roles in Code: Inside your controller actions or views, you can also check the user’s roles programmatically.

Step 5: Secure Views: You can secure views based on roles by using the “User.IsInRole” method.

Role-based authorization in ASP.NET provides a way to restrict access.Implementing role-based authorization in ASP.NET allows you to control access to various parts of your application based on the roles assigned to users. This method is especially useful for applications with multiple user roles and levels of access permissions.

In addition to role-based authorization, policy-based authorization provides more granular control. Policies enable you to encapsulate complex authorization logic.

Claims-Based Authorization:

Claims-based authorization in ASP.NET enables you to make access control decisions based on a user’s claims. Claims represent specific attributes or characteristics of the user and may include information such as roles, email addresses, or custom data. This approach offers a flexible and granular method for managing authorization in your application.

Here’s a guide for implementing claims-based authorization in ASP.NET:

Step 1: Understanding Claims: In ASP.NET, a claim is a piece of information about the user, typically represented as key-value pairs. Examples of claims include user roles, email addresses, or any other custom information relevant to your application.

Step 2: Assign Claims to Users: Claims are assigned to users during the authentication process. You can include claims when creating or updating the user’s identity. ASP.NET provides the “ClaimsIdentity” class for this purpose.

Step 3: Configure Claims-Based Authorization: In your application, you can use the “[Authorize]” attribute along with the “User.HasClaim” method to control access based on claims.

Step 4: Define Policies: You can define policies in your application’s startup configuration. Policies encapsulate authorization logic and can include requirements based on claims.

Step 5: Check Claims in Code: Inside your controller actions or views, you can check the user’s claims programmatically.

Step 6: Secure Views: You can secure views based on claims by using the “User.HasClaim” method.

Implementing claims-based authorization in ASP.NET allows you to make access control decisions based on the user’s specific attributes or characteristics. This method is especially useful when you require fine-grained control over authorization and want to assign different sets of attributes to different users.

Policy-Based Authorization:

Policy-based authorization, which was introduced in ASP.NET Core, allows you to define complex access control policies.

Policies encapsulate authorization logic and can be applied to controllers or action methods via the Authorize attribute.

Best Practices:

Secure Password Storage:

Use secure password hashing algorithms like bcrypt or Argon2 to store passwords securely.

Implement password policies to enforce strong passwords.

Two-Factor Authentication (2FA):

Encourage or enforce the use of two-factor authentication for an additional layer of security.

Regularly Review and Update Access Controls:

Periodically review and update roles, claims, and access control policies.

Remove unnecessary privileges to minimize the attack surface.

Logging and Monitoring:

Implement logging to track authentication and authorization events.

Monitor logs for suspicious activities and potential security breaches.

Conclusion:

Proper authentication and authorization are critical for developing secure and reliable ASP.NET applications. Understanding available authentication methods and implementing effective authorization strategies allows developers to create applications that protect sensitive data and provide a seamless user experience while maintaining a strong security posture. Staying up to date on security best practices and ASP.NET community updates is critical for adapting to evolving security challenges.

Dependency Injection in ASP.NET Core

Building Modular and Testable Applications with Dependency Injection in ASP.NET Core

Introduction:

A key component of developing ASP.NET Core applications that encourages modularity, maintainability, and testability is dependency injection, or DI. In this post, we’ll examine the foundations of dependency injection in ASP.NET Core, as well as its advantages and practical uses for developing organized and expandable applications.

Understanding Dependency Injection:

Dependency injection is a design pattern that assists in the management of dependencies among various components in a software system. It refers to the technique of supplying the objects that a class requires (its dependencies) from outside rather than creating them within the class itself in the context of ASP.NET Core. This method makes classes more modular and testable.

Benefits of Dependency Injection in ASP.NET Core:
1. Modular Code: By injecting dependencies into classes, each class can concentrate on its own functionality without being tethered to the implementation details of its dependencies. As a result, the code becomes more modular and maintainable.
2. Testability: Dependency injection makes unit testing easier by allowing developers to replace real implementations of dependencies with mock or test implementations. This facilitates the isolation and testing of individual components.
3. Extensibility: It is easier to extend an application’s functionality with dependency injection by introducing new components or swapping out existing ones. This is especially useful when evolving and scaling an application.
Implementing Dependency Injection in ASP.NET Core:
1. Service Registration:

Services in ASP.NET Core are registered at application startup in the dependency injection container. Services can be added to the container via the ‘ConfigureServices’ method in the ‘Startup’ class.

public void ConfigureServices(IServiceCollection services)

{

    services.AddTransient<IMyService, MyService>();

    // Add more services...

}

‘IMyService’ is the interface in this example, and ‘MyService’ is the matching implementation. ‘Transient’ means that each time a request is made, a new instance of ‘MyService’ is created.

2. Constructor Injection:

Use the constructor of a class to inject dependencies into it. The necessary dependencies are automatically provided by the DI container when a class instance is created.

public class MyController : Controller

{

    private readonly IMyService _myService;

    public MyController(IMyService myService)

    {

        _myService = myService;

    }

    // Controller actions...

}

3. Using Dependency Injection in Middleware:

Dependency injection can also help middleware components in the ASP.NET Core request processing pipeline. The ‘Invoke’ method can have services injected into it.

public class MyMiddleware

{

    private readonly RequestDelegate _next;

    private readonly IMyService _myService;

    public MyMiddleware(RequestDelegate next, IMyService myService)

    {

        _next = next;

        _myService = myService;

    }

    public async Task Invoke(HttpContext context)

    {

        // Use _myService...

await _next(context);

    }

}

Scopes and Lifetimes of Services:

Several service lifetimes, such as ‘Transient’, ‘Scoped’, and ‘Singleton’, are supported by ASP.NET Core. Managing the lifespan of service instances requires an understanding of these lifetimes.

1. Transient: Whenever an instance is requested, a new one is created.
2. Scoped: Each request generates a single instance. Within the parameters of an HTTP request, it is shared.
3. Singleton: For the duration of the application, only one instance is created.
Best Practices for Dependency Injection in ASP.NET Core:

1. Choose Constructor Injection: For improved readability and maintainability, inject dependencies via the constructor.

2. Employ Interfaces: Write code that checks against interfaces as opposed to specific implementations. This encourages testability and flexibility.

3. Avoid the Service Location Anti-Pattern: Avoid the ‘ServiceLocator’ pattern, which involves retrieving services directly from the container within a class.

4. Register Services as Interfaces: When registering services, use interfaces rather than concrete implementations.

services.AddTransient<IMyService, MyService>();

  Conclusion:

Dependency injection is a powerful design pattern that improves the design, testability, and maintainability of ASP.NET Core applications significantly. Developers can create modular, extensible, and testable applications by leveraging the built-in dependency injection container. Understanding dependency injection principles is critical for developing robust and scalable ASP.NET Core applications.

Database Access in ASP.NET Core using Entity Framework Core

Introduction:

Many web applications depend on database access, which is made easier and more efficient in ASP.NET Core by Entity Framework Core (EF Core). In this post, we’ll examine the foundations of Entity Framework Core and how ASP.NET Core applications can use it to achieve effective and adaptable database access.

Overview of Entity Framework Core:

Entity Framework Core is an object-relational mapping (ORM) framework that enables.NET objects to be used by developers to communicate with databases. Instead of working directly with SQL queries, it allows developers to work with databases using a high-level, object-oriented API.

Entity Framework Core’s key features include:

Model-First Approach: Use C# classes to define your data model, and EF Core will create the corresponding database schema.

LINQ Support: When querying databases, use Language-Integrated Query (LINQ), which makes it easier to express database queries in C# syntax.

Database Migrations: EF Core supports database migrations, allowing for simple schema changes and updates as your application evolves.

Cross-Platform Compatibility: EF Core is designed to work with various database providers, giving you the option of using SQL Server, MySQL, SQLite, and others.

Setting Up Entity Framework Core in ASP.NET Core:

Install the NuGet package for Entity Framework Core:

Install the NuGet package Entity Framework Core in your ASP.NET Core project:

dotnet add package Microsoft.EntityFrameworkCore

Configure Database Provider: Select a database provider (for example, SQL Server) and install the appropriate provider package:

dotnet add package Microsoft.EntityFrameworkCore.SqlServer

Configure the database provider using the ConfigureServices method in your Startup.cs file:

public void ConfigureServices(IServiceCollection services)

{

    services.AddDbContext<ApplicationDbContext>(options =>

        options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

}

Create DbContext:

Make a class that derives from DbContext in order to create DbContext. This class defines DbSet properties for every entity and represents the database context.

public class ApplicationDbContext : DbContext

{

    public DbSet<User> Users { get; set; }

    // Add more DbSet properties for other entities

}

Configuring the Connection String: Open the appsettings.json file and set the database connection string there.

{

  "ConnectionStrings": {

    "DefaultConnection": "YourConnectionString"

  },

  // Other configurations...

}

Working with Entities and DbContext:

Defining Entities:

Make classes in C# that correspond to your entities. EF Core will map to database tables using these classes.

public class User

{

    public int Id { get; set; }

    public string UserName { get; set; }

    public string Email { get; set; }

    // Other properties...

}

CRUD Operations:

In your application code or controllers, use the DbContext to perform CRUD operations:

public class UserController : ControllerBase

{

    private readonly ApplicationDbContext _context;

    public UserController(ApplicationDbContext context)

    {

        _context = context;

    }

    [HttpGet]

    public ActionResult<IEnumerable<User>> GetUsers()

{

        return _context.Users.ToList();

    }

    [HttpPost]

    public ActionResult<User> AddUser([FromBody] User newUser)

    {

        _context.Users.Add(newUser);

        _context.SaveChanges();

        return newUser;

    }

    // Implement other CRUD operations (Update, Delete) as needed...

}

Database Migrations:

With EF Core, you can use migrations to change the structure of your database. To create and implement migrations, execute the following commands:

dotnet ef migrations add InitialCreate

dotnet ef database update

To establish the initial database schema and implement the modifications, these commands produce SQL scripts.

Conclusion:

Entity Framework Core offers a strong and adaptable ORM framework while streamlining database access in ASP.NET Core. Without requiring in-depth SQL knowledge, developers can effectively interact with databases by defining entities, setting up a DbContext, and using LINQ for querying. EF Core provides a dependable and efficient method for database access in ASP.NET Core, regardless of the size of your project—from a small application to a large enterprise system.

 

 

Web API with ASP.NET Core using MVC

Creating a web API with ASP.NET Core using the MVC (Model-View-Controller) pattern entails creating controllers to handle HTTP requests, models to represent data, and routes for the API. A step-by-step guide to creating an MVC web API with ASP.NET Core is provided below.

Step 1 Install the Necessary Software

Check that your machine has the.NET SDK installed.

Step 2 Create a New ASP.NET Core MVC Web API Project

Run the following commands in a terminal or command prompt

dotnet new mvc -n MyMvcWebApi

cd MyMvcWebApi

This will create a new ASP.NET Core MVC project called MyMvcWebApi and navigate to its directory.

Step 3 Explore the Project Structure

Launch your preferred IDE and open the project. Controllers, Models, and Views are among the folders in the project structure.

Controllers In this section, you will define your API controllers.

Models To represent your data, you can create model classes.

Views Although views are not required for an API, this folder is included in the standard MVC structure.

Step 4 Create a Model

To represent your data, create a model class. Create a file called Item.cs in the Models folder, for example

public class Item

{

    public int Id { get; set; }

    public string Name { get; set; }

}

Step 5 Establish a Controller

Add a new file to the Controllers folder, such as ItemsController.cs, to create a controller

using Microsoft.AspNetCore.Mvc;

using System.Collections.Generic;

namespace MyMvcWebApi.Controllers

{

    [Route(api[controller])]

    [ApiController]

    public class ItemsController  ControllerBase

    {

        private static ListItem _items = new ListItem

   {

            new Item { Id = 1, Name = Item 1 },

            new Item { Id = 2, Name = Item 2 },

            new Item { Id = 3, Name = Item 3 }

        };

GET apiitems

        [HttpGet]

        public ActionResultIEnumerableItem Get()

        {

            return _items;

        }

GET apiitems1

        [HttpGet({id})]

        public ActionResultItem Get(int id)

        {

            var item = _items.Find(i = i.Id == id);

            if (item == null)

                return NotFound();

   return item;

        }

         POST apiitems

        [HttpPost]

        public ActionResultItem Post([FromBody] Item newItem)

        {

   newItem.Id = _items.Count + 1;

            _items.Add(newItem);

            return CreatedAtAction(nameof(Get), new { id = newItem.Id }, newItem);

        }

         PUT apiitems1

        [HttpPut({id})]

public IActionResult Put(int id, [FromBody] Item updatedItem)

        {

            var existingItem = _items.Find(i = i.Id == id);

            if (existingItem == null)

                return NotFound();

existingItem.Name = updatedItem.Name;

            return NoContent();

        }

         DELETE apiitems1

        [HttpDelete({id})]

        public IActionResult Delete(int id)

{

            var itemToRemove = _items.Find(i = i.Id == id);

            if (itemToRemove == null)

                return NotFound();

            _items.Remove(itemToRemove);

            return NoContent();

         }

     }

}

Step 6 Run the Program

Enter the following command at the command prompt or terminal

dotnet run

The URL for your API will be http://localhost:5000 or https://localhost:5001. Open an API testing tool such as Postman:

GET Request: To retrieve items, open https://localhost:5001/api/items.
POST Request: To add a new item, submit a POST request with a JSON body to https://localhost:5001/api/items.
PUT Request: To update an item, submit a PUT request with a JSON body to https://localhost:5001/api/items/1.
DELETE Request: To delete an item, send a DELETE request to https://localhost:5001/api/items/1.

Step 7 Explore and Extend

To improve your web API, investigate additional ASP.NET Core MVC features like middleware, authentication, dependency injection, and model binding. Depending on the needs of your application, you can handle various HTTP methods, define more models, and add more controllers.

Developing ASP.NET Core MVC Web Applications:

Introduction:

Creating dynamic and interactive web pages using the ASP.NET Core framework is required when developing ASP.NET Core MVC (Model-View-Controller) web applications. Model, View, and Controller (MVC) is a design pattern that divides an application into three main components: Model, View, and Controller. ASP.NET Core MVC is a lightweight, cross-platform, open-source framework for building modern, scalable web applications.

Here is a step-by-step tutorial for creating ASP.NET Core MVC web applications:

1. Install Prerequisites:

As your development environment, install Visual Studio or use Visual Studio Code.

Install the.NET SDK from the Microsoft website:

https://dotnet.microsoft.com/download

2. Create a new ASP.NET Core MVC project as follows:

Open Visual Studio and choose “Create a new project.”

Select “ASP.NET Core Web App” and then “ASP.NET Core with MVC” as the template.

Configure the project parameters and then click “Create.”

3. Understand the Project Structure:

Look into the project structure to learn about the key components:

Controllers: Controllers are responsible for handling user input and orchestrating interactions between the model and the view.

Views: Present information to the user and collect user input.

Models: Represent the application’s data and business logic.

4. Define Models:

Model classes should be created to represent the data entities in your application.

Data annotations can be used to validate data and define metadata.

public class Product

{

    public int Id { get; set; }

    [Required]

    public string Name { get; set; }

    public decimal Price { get; set; }

}

5. Create Controllers:

To handle user requests and interact with models, create controllers.

Define controller actions to respond to specific HTTP requests.

public class ProductController : Controller

{

    public IActionResult Index()

    {

        // Retrieve and return a list of products

        return View(products);

    }

public IActionResult Details(int id)

    {

        // Retrieve a specific product by id and return it

        return View(product);

    }

}

6. Develop Views:

To define the presentation layer, create view files (.cshtml).

To display dynamic content, use Razor syntax to embed C# code within HTML.

@model List<Product>

<h2>Product List</h2>

<ul>

    @foreach (var product in Model)

    {

        <li>@product.Name - $@product.Price</li>

    }

</ul>

7. Configure Routing:

Define routes in the Startup.cs file to map URLs to controller actions.

app.UseEndpoints(endpoints =>

{

    endpoints.MapControllerRoute(

        name: "default",

        pattern: "{controller=Home}/{action=Index}/{id?}");

});

8. Handle Form Submissions:

In controllers, use the HttpPost attribute to handle form submissions.

[HttpPost]

public IActionResult Create(Product product)

{

    // Validate and save the new product

    return RedirectToAction("Index");

}

9. Implement Data Access:

To interact with databases, use Entity Framework Core or other data access technologies.

10. If desired, include authorization and authentication:

Authenticate and authorize users in accordance with the specifications of your application.

11. Test Your Application:

Run your application locally and verify various scenarios to test it.

12. Publish Your Application:

Publish your ASP.NET Core MVC application to a cloud platform or hosting environment.

Note: Always refer to the official ASP.NET Core documentation for more information on each stage of development: https://docs.microsoft.com/en-us/aspnet/core/

 

Microservices Architecture with DOTNET Core

Introduction:
The ability of microservices architecture to break down large, monolithic applications into smaller, independent services has led to widespread adoption. This article delves into the design principles and implementation strategies for developing microservices with DOTNET Core, Microsoft’s versatile and powerful framework.

Understanding Microservices Architecture:

Microservices is a design style in which an application is made up of loosely coupled, independently deployable services. Each service is intended to carry out a specific business function and communicates with other services via well-defined APIs.

Design Principles:
1. Single Responsibility Principle (SRP): Each microservice should be responsible for a single business capability. This ensures ease of use and maintainability.
2. Decentralized Data Management: Databases belong to microservices. Because of this decentralization, dependencies are reduced and each service is free to select the database technology that best meets its needs.
3. Inter-Service Communication: APIs are used by services to communicate with one another, and they frequently use lightweight protocols such as HTTP/REST or messaging queues. This allows for independence and flexibility in technology stack selection.
4. Fault Tolerance and Resilience: Create services that are resistant to failure. To handle faults gracefully, use mechanisms such as circuit breakers and retries.
5. Continuous Integration and Deployment (CI/CD): Use CI/CD techniques to automate the processes of building, testing, and deployment. This guarantees the delivery of microservices quickly and consistently.
6. Scalability: Microservices can be scaled independently based on demand. By horizontally scaling instances, you can design services to handle varying levels of load.

Implementation with DOTNET Core:
1. Service Development: For each microservice, create a separate DOTNET Core project. Build web APIs with ASP DOTNET Core and consider high-performance communication technologies like gRPC.
2. API Gateway: Set up an API Gateway to manage and route requests to the proper microservices. In Azure, tools such as Ocelot and API Gateway can be used.
3. Service Discovery: To dynamically locate and call services, use service discovery tools such as Consul or Eureka. This is critical for dealing with the fluid nature of microservices.
4. Containerization: Use Docker to containerize each microservice. This ensures consistency across environments and makes deployment easier.
5. Orchestration with Kubernetes: Use Kubernetes to orchestrate and manage containers. Kubernetes makes it easier to deploy, scale, and manage microservices.
6. Logging and Monitoring: Consolidate logging and monitoring. Tools such as the ELK stack (Elasticsearch, Logstash, Kibana) or Application Insights can provide insights into the behavior of microservices.
7. Security: Implement an all-encompassing security strategy. Utilize OAuth for authentication, JWT for token-based authorization, and HTTPS for secure communication.
8. Testing: For each microservice, perform unit testing, integration testing, and end-to-end testing. In this context, tools like xUnit, NUnit, and Postman can be useful.
9. Database Management: Select databases based on the needs of the microservices. Accept polyglot persistence and think about SQL and NoSQL databases.
10. Event-Driven Architecture: Think about using event-driven patterns with message brokers such as RabbitMQ or Apache Kafka. Asynchronous communication between microservices is enabled by events.

Conclusion:
Using DOTNET Core to build microservices necessitates adhering to architectural principles that prioritize independence, scalability, and maintainability. Developers can create a robust microservices ecosystem that meets the demands of modern, scalable applications by using a containerized and orchestrated approach. The combination of DOTNET Core and microservices unleashes the power of agile development, rapid deployment, and efficient scaling, enabling organizations to deliver resilient and scalable applications in today’s dynamic computing landscape.

This article is intended to be a gentle introduction to the fundamentals of Java programming, covering key concepts, syntax, and the fundamental building blocks that serve as the foundation of this widely used language.

Java has been a well-liked option for developers creating everything from mobile applications to enterprise-level systems because of its “write once, run anywhere” mentality. If you’ve never used Java before, this tutorial will take you through the first steps of setting up your environment and writing your first Java program.

 

How to Install the JDK (Java Development Kit):

You have to install the JDK before you can begin writing Java code. Take these actions:

To obtain the most recent JDK version, go to OpenJDK or the official Oracle website.

Launch the installer and adhere to your operating system’s on-screen directions.

Once the installation is complete, modify the JDK installation directory by setting the JAVA_HOME environment variable.

 

Configuring the IDE (Integrated Development Environment):

Even though a basic text editor can be used to write Java code, using an IDE can greatly improve your development experience. NetBeans, Eclipse, and IntelliJ IDEA are a few of the well-known Java IDEs. To set IntelliJ IDEA up, do the following steps:

From the official website, download and install IntelliJ IDEA Community Edition.

Launch IntelliJ IDEA and select the relevant JDK version.

Select the “Hello World” template when starting a new project.

 

How to Write Your First Java Program:

Now that your environment has been configured, let’s write a simple “Hello, World!” program to ensure that everything is working properly.

// HelloWorld.java

public class HelloWorld

 {

    public static void main(String[] args)

    {

        System.out.println(“Hello, World!”);

    }

}

Name the file HelloWorld.java and save it.

To compile the program, launch a command prompt or terminal, go to the directory where your file is located, and type:

javac HelloWorld.java

If there are no errors, execute the program as follows:

java HelloWorld

Congratulations! You’ve just finished writing and running your first Java program.

How to Understand the “Hello, World!” Program:

public classHelloWorld : Creates a HelloWorld class.

The program’s entry point is public static void main(String[] args). It is the point at which the program begins to run.

System.out.println(“Hello, World!”); : The string “Hello, World!” is printed to the console.

 

 The Fundamental Structure:

Classes are used to organize Java programs. Each class represents a different aspect of your program. Here’s an example of a simple Java program structure:

public class MyFirstProgram

{

    public static void main(String[] args)

   {

        // Your code goes here

    }

}

public class MyFirstProgram: Declares the MyFirstProgram class. The keyword public indicates that the class can be accessed from other classes.

public static void main(String[] args): The main method, from which the program executes. In a Java application, this signature is always present.

 

Comments

The compiler ignores comments, which are used to annotate your code. They can be either single or multi-line.

// This is a single-line comment

/*

    This is a multi-line comment.

    It can span multiple lines.

*/

Comment your code to make it more readable and understandable for yourself and others.

 

Variables and Data Types:

Variables are used to store data in Java. Each variable has a data type that specifies what type of data it can store.

int age = 33;           // Integer data type

double price = 10.75;   // Double-precision floating-point data type

char grade = ‘S’;       // Character data type

String name = “RAM”;   // String data type

boolean isJavaFun = true; // Boolean data type

In Java, data types include int, double, char, String, and boolean. =: The assignment operator.

 

Statements and Semicolons:

Statements in Java are instructions that perform actions. Semicolons are used to end statements.

int x = 1;              // Variable declaration statement

System.out.println(x);  // Method call statement

x = x + 1;              // Assignment statement

A statement’s end is indicated by the semicolon ;.

 

Code Blocks:

Code blocks combine several statements into one group. Curly braces {} define them.

public class addition

{

    public static void main(String[] args)

    {

        // Start of the main method block

        int a = 25;

        int b = 75;

        int sum = a + b;

        System.out.println(“Sum: ” + sum);

        // End of the main method block

    }

}

 

Whitespace:

Although whitespace is not sensitive in Java, it is essential for code readability. To improve the visual appeal of your code, use indentation and spaces.

public class Demo

{

    public static void main(String[] args)

      {

        int a = 51;

        int b = 100;

        if (a < b)

        {

            System.out.println(“a is less than b”);

        }

    }

}

 

Becoming an expert Java programmer starts with understanding Java’s syntax. More complex syntax and ideas will come up as you learn more about Java development. Develop your skills, try new things, and add to your knowledge gradually to become a self-assured Java developer. Have fun with coding!

View in SQL

View in SQL

A view in SQL is a virtual table created from the results of a SELECT query. Views simplify complex queries, encapsulate logic, and provide an abstraction layer over the underlying tables. They can be used to present data in a more meaningful or secure manner than querying the underlying tables directly. Here’s a quick rundown of how to create and use views in SQL:

Creating a View:

The CREATE VIEW statement is used to create a view. The fundamental syntax is as follows:

CREATE VIEW view_name AS

SELECT column_name_1, column_name_2, …

FROM table_name

WHERE condition;

For example, let us create a new table called studentdata using the syntax shown below.

create table studentdata(

sno int,

sname varchar(100),

slocaction varchar(100),

smothertongue varchar(100));

Insert some records as well using the syntax shown below.

insert into studentdata values(1, ‘RAM’, ‘CHENNAI’, ‘TAMIL’)

insert into studentdata values(2, ‘RAJ’, ‘CHENNAI’, ‘HINDI’)

insert into studentdata values(3, ‘RAVI’, ‘HYDERABAD’, ‘TELUGU’)

insert into studentdata values(4, ‘RAJESH’, ‘HYDERABAD’, ‘TAMIL’)

insert into studentdata values(5, ‘RAJIV’, ‘CHENNAI’, ‘TELUGU’)

Select query syntax can be used to display the table records.

SELECT * FROM studentdata

Create a view using the syntax shown below.

CREATE VIEW TN AS

SELECT * FROM studentdata

WHERE slocaction = ‘CHENNAI’

Using a View:

After you’ve created a view, you can query it like a regular table with the following syntax:

SELECT * FROM view_name

With reference to the given example,

SELECT * FROM TN

Updating a View:

You can use the ALTER VIEW statement to update views:

ALTER VIEW view_name AS

SELECT column_name_1, column_name_2, …

FROM table_name

WHERE condition;

In Microsoft SQL Server, you can use the CREATE OR ALTER VIEW statement to replace an existing view or create a new one. This is similar to the CREATE OR REPLACE VIEW syntax found in other database systems. Using the preceding example:

ALTER VIEW TN AS

SELECT * FROM studentdata

WHERE smothertongue = ‘TAMIL’

Dropping a View:                

The DROP VIEW statement is used to remove a view:

DROP VIEW employee_view;

Thinking back to the earlier illustration:

DROP VIEW TN

 

Multiple Views:

Views enable you to create a virtual table in a relational database based on the results of a SELECT query. You can use JOIN operations in your SELECT statement to combine data from multiple tables in a view. Here’s a general guide to creating a view with multiple tables:

Consider the following scenario: you have two tables: customers and orders. The customers table contains information about customers, and the orders table contains information about the orders that these customers have placed.

— Sample customers table

CREATE TABLE customers (

    CustomerId INT PRIMARY KEY,

    CustomerName VARCHAR(50),

    Email VARCHAR(50)

);

— Sample orders table

CREATE TABLE orders (

    OrderId INT PRIMARY KEY,

    CustomerId INT,

    OrderDate DATE,

    TotalAmount DECIMAL(10, 2),

    FOREIGN KEY (CustomerId) REFERENCES customers(CustomerId)

);

Let us also insert some sample records into both tables using the insert query:

INSERT INTO customers VALUES (1, ‘RAM’, ‘ram@mail.com’)

INSERT INTO customers VALUES (2, ‘RAJ’, ‘raj@mail.com’)

INSERT INTO customers VALUES (3, ‘RAVI’, ‘ravi@mail.com’)

INSERT INTO orders VALUES (101, 1, ‘2023/11/02’, 10000)

INSERT INTO orders VALUES (102, 2, ‘2023/11/03’, 12000)

Check it out with the following select query:

SELECT * FROM customers

SELECT * FROM orders

Let’s now create a view that combines data from both tables:

CREATE VIEW CustomerOrderView AS

SELECT

    c.CustomerId,

    c.CustomerName,

    c.Email,

    o.OrderId,

    o.OrderDate,

    o.TotalAmount

FROM

    customers c

JOIN

    orders o ON c.CustomerId = o.CustomerId;

The CustomerOrderView view is created in this example by selecting specific columns from both the customers and orders tables. The JOIN clause is used to join rows from both tables using the CustomerId column in common.

After you’ve created the view, you can query it like any other table:

SELECT * FROM CustomerOrderView

Remember that the exact syntax can change based on the database management system (SQL, PostgreSQL, MySQL, etc.) you are using. Depending on the system you are working with, modify the SQL statements as necessary.

SQL and .NET (sometimes spelled DOTNET) are two separate technologies that are commonly utilized in software development. SQL, which stands for Structured Query Language, is a powerful computer language that was created primarily for maintaining and manipulating relational databases. It provides a standardized approach for developers to accomplish operations including accessing data, entering records, updating information, and designing database structures.

.NET, on the other hand, is a framework developed by Microsoft for building various types of applications, including desktop, web, and mobile applications. It provides a comprehensive set of libraries and tools for developers to build, deploy, and run applications. .NET supports multiple programming languages, including C#, F#, and Visual Basic, and it includes a runtime, a set of libraries, and development tools.

While SQL is primarily focused on working with databases and managing data, .NET is a broader framework that covers a wide range of application development aspects. However, it’s common for developers to use SQL in conjunction with .NET when building applications that require interaction with a database.

In a typical scenario, a .NET application may use SQL to store and retrieve data from a relational database. This interaction is often facilitated by using an Object-Relational Mapping (ORM) framework, such as Entity Framework, which is a popular component of the .NET ecosystem. Entity Framework allows developers to work with databases using object-oriented principles, making it easier to integrate database operations into .NET applications.

Do you want to know if.NET is still in demand?

There is no need to look any further! .NET is an open-source web framework that is one of the most popular web application development frameworks for creating dynamic websites.

Validation in ASP.NET MVC

Validation is an essential component of any web application, including those created with ASP.NET MVC. It guarantees that data given by users is correct, secure, and satisfies the relevant standards. ASP.NET MVC includes numerous means for performing validation, and I’ll go over some of the major principles and strategies for creating validation in ASP.NET MVC.

 

1.  Model Validation: A basic method for validating data entered into a form is model validation. It entails adding characteristics that specify validation criteria to your model classes through annotation. The most prevalent qualities consist of:

[Required]: Indicates the necessity of a certain attribute.

[StringLength]: Indicates a string property’s minimum and maximum length.

[Range]: Indicates a possible range of values for a numerical attribute.

[RegularExpression]: Uses a regular expression pattern to validate a property.

[Compare]: Compare to ensure two properties of a model has same value.

[DataType(DataType.Password)] : converts the text mode to password mode.

Here’s an example of how to apply the following attributes:

public class Student

{

[Required]

public string FirstName { get; set; }

[StringLength(50, MinimumLength = 3)]

public string LastName { get; set; }

[Range(18, 100)]

public int Age { get; set; }

[RegularExpression(@”^[a-zA-Z0-9]*$”, ErrorMessage = “Invalid characters”)]

public string Username { get; set; }

[Required]

[DataType(DataType.Password)]

public string Password { get; set; }

[Compare(“Password”)]

public string ConfirmPassword { get; set; }

}

 

2. Client-Side Validation: Based on the validation characteristics added to your model properties, ASP.NET MVC can produce client-side validation code. This gives users immediate feedback in their web browsers before they submit the form. You must add the essential JavaScript libraries, such as jQuery Validation, in your project to enable client-side validation.

 

3. ModelState: ASP.NET MVC automatically populates the ModelState object with validation errors after a form is submitted. If there are any validation failures, you can check ModelState.IsValid and display error warnings to the user.

Here’s an example of how to apply the following attribute:

[HttpPost]

public ActionResult Create (Student model)

{

    if (ModelState.IsValid)

    {

        // Process the data and save it.

        return RedirectToAction(“Success”);

    }

    return View(model);

}

 

4. Displaying Validation Errors: The @Html.ValidationMessageFor and @Html.ValidationSummary helper methods can be used to display validation errors in your views. These show error warnings for either the entire model or just a subset of its properties.

Here’s an example of how to apply the following attribute:

@Html.ValidationSummary()

@Html.LabelFor(model => model.FirstName)

@Html.EditorFor(model => model.FirstName)

@Html.ValidationMessageFor(model => model.FirstName)

 

5. Custom Validation: By implementing the IValidatableObject interface or by deriving from ValidationAttribute and defining custom validation attributes, you can establish custom validation rules. You can use this to provide unique validation logic for your models.

 

6. Remote Validation: Remote validation allows you to execute server-side validation checks without requiring a complete page postback. To accomplish this, use the [Remote] attribute in conjunction with a controller action.

 

7. Anti-Forgery Token (CSRF Protection): Anti-forgery tokens must be included in your forms to guard against Cross-Site Request Forgery (CSRF) attacks. In your forms, you can utilize the @Html.AntiForgeryToken() helper method and validate it on the server with the [ValidateAntiForgeryToken] property.

 

These are the main ASP.NET MVC validation features. By employing these methods, you may guarantee that user-submitted data is secure and legitimate, assisting in preserving the application’s integrity.

Data Access in ASP.NET MVC

Data access in ASP.NET MVC refers to the process of retrieving, updating, and modifying data from a database or other data sources for use in a web application. There are various ways to accomplish data access in ASP.NET MVC, and the technology you choose generally relies on the requirements and design of your application. Here are some popular data access methods in ASP.NET MVC:

1. Entity Framework (EF): Microsoft’s Entity Framework is a prominent Object-Relational Mapping (ORM) framework. It enables you to work with your data by abstracting the underlying database using highly typed.NET objects. Entity Framework requires you to define your data model as C# classes, and Entity Framework will construct the SQL queries needed to interface with the database.

Follow these steps to get started with Entity Framework in ASP.NET MVC:

a. Use NuGet to install Entity Framework.

b. Create a DbContext-derived data context class.

Create entity classes to represent database tables.

Interact with your data using LINQ queries.

2. ADO.NET: ADO.NET is a lower-level data access technology that allows you to work directly with databases using data providers. ADO.NET can be used to make database connections, run SQL queries, and retrieve data. While it gives you greater power, it often requires you to write more code than Entity Framework.

You can utilize ADO.NET in ASP.NET MVC by following these general steps:

a. Use SqlConnection to create a database connection.

b. Using SqlCommand, create and run SQL queries or stored procedures.

c. To get data, use SqlDataReader or any data reader.

3. Dapper: Dapper is an ADO.NET-based lightweight Object-Relational Mapping (ORM) library. By offering a quick and simple method to map database records to C# objects without the complexities of Entity Framework, it streamlines data access.

You may use Dapper in ASP.NET MVC by following these steps:

a. Use NuGet to install Dapper.

b. Create SQL queries, then execute them using Dapper’s extension methods and map the results to objects.

 4. Web API and HTTP Services: In some cases, you might be able to receive data from remote servers using web APIs or HTTP services rather than directly accessing a database. To send HTTP queries to external APIs and use the results in your MVC application, you can use libraries like as HttpClient.

You can use HTTP services and web APIs in the following ways:

a. Create controller actions that send HTTP queries.

b. Create C# objects by deserializing the XML or JSON answers.

Selecting the best approach for data access security, error management, and performance optimization is crucial, regardless of the data access method you use. A clean and maintainable architecture should also be achieved by keeping your data access code distinct from your controllers and views. For example, you can encapsulate data access functionality in repositories or services.

Routing in ASP.NET MVC

Routing is a basic element in ASP.NET MVC that governs how URLs are mapped to controller actions in your application. It specifies how incoming requests are handled, as well as which controller and action methods are used to generate the answer. Routing is required when creating clean, user-friendly URLs for your web application.

The following are the main elements and ideas around routing in ASP.NET MVC:

Route Table: The routing configuration in ASP.NET MVC is normally set up in the ‘RouteConfig’ class in your project’s ‘App_Start’ folder. A set of route definitions is stored in the ‘RouteConfig’ class. The ‘MapRoute’ method is used to add these route definitions to the ‘RouteTable.Routes’ collection.

Route Definitions: A route specification contains the URL pattern, the default settings, as well as the controller and action to be executed when a specific URL is matched. An example of a route definition is as follows:

routes.MapRoute(

    name: “Default”,

    url: “{controller}/{action}/{id}”,

    defaults: new { controller = “Home”, action = “Index”, id = UrlParameter.Optional }

);

In this case, the route matches URLs like /Home/Index and delivers them to the controller and action methods defined.

Route Parameters: You can include placeholders like {controller}, {action}, and {id} in the URL pattern encased in curly brackets in the route definition. The arguments indicated by these placeholders are those that will be taken from the URL and provided to the relevant action method. As demonstrated in the last example, the route parameters may also have default values.

Route Constraints: To limit the values that can be entered for route parameters, you can apply restrictions. To guarantee that only numerical values match the route, you can, for example, stipulate that the id parameter must be an integer.

Route Handling: The routing system looks at the URL in an HTTP request and attempts to match it with one of the route definitions in the route table. In the event that a match is discovered, the relevant controller and action are called using the URL’s extracted arguments.

Attribute Routing: ASP.NET MVC allows attribute routing in addition to convention-based routing (as demonstrated in the RouteConfig example). With attribute routing, you may use attributes to define routing information directly on your controller activities. This gives individual actions greater routing flexibility and control.

As an example of attribute routing, consider the following:

[Route(“products/details/{id}”)]

public ActionResult Details(int id)

{

    // Action logic here

}

You can have detailed control over the URL structure for every action method with attribute routing.

In summary, routing is an essential component of ASP.NET MVC because it makes it possible to construct RESTful web applications, organize controllers and actions more effectively, and produce neat, SEO-friendly URLs. When routing is set up correctly, requests are routed to the right controller actions, which provide the user the right response.

Controllers in ASP.NET MVC

Controllers in ASP.NET MVC (Model-View-Controller) are critical in accepting incoming HTTP requests, processing them, and sending appropriate responses to the client. Controllers are in charge of regulating the application’s flow, communicating with models and views, and handling user input. Here are some important points to remember regarding controllers in ASP.NET MVC:

Controllers’ Role: Clients, usually web browsers, send requests over HTTP to controllers. They use the request URL and HTTP verb (GET, POST, etc.) to identify the action method to do. The logic for handling user input, making choices, and coordinating with models and views to produce a response is included in controllers.

Controller Naming Convention: In ASP.NET MVC, controllers usually have names that conclude in “Controller.” HomeController, DefaultController, and UserController are a few examples.

Action Methods: Action methods, which are public methods that respond to certain HTTP requests, make up controllers. The HTTP verbs that action methods respond to are indicated by characteristics like [HttpGet] or [HttpPost]. In order to render the answer, they must process user input, interact with models (data access), and choose the right view.

Routing: Routing is used by the ASP.NET MVC framework to map incoming URLs to controllers and associated action methods. The RouteConfig.cs file is frequently used to define the default route settings.

Parameters and Model Binding: Parameters from the URL, form data, query string, or other sources can be passed to action methods. Model binding is used by ASP.NET MVC to automatically connect incoming data to method parameters.

ActionResult: Action methods will either return an ActionResult or a derived class such as ViewResult, RedirectResult, or JsonResult. The type of answer given to the client is determined by the result type.

Dependency Injection: It is common practice to inject services and dependencies into controllers to make them more tested and manageable.

Filters:

To provide behavior and manage the execution flow of action methods, controllers can be decorated with filters such as permission filters or action filters.

Testing: Unit testing is a useful tool for verifying that controllers operate as intended. Mocking frameworks are frequently used to test controller activities and simulate HTTP requests.

RESTful Controllers: RESTful APIs can be developed with ASP.NET MVC, in which controllers manage the HTTP verbs GET, POST, PUT, and DELETE to carry out CRUD actions on resources.

In summary, controllers are an essential component of the ASP.NET MVC architecture and are in charge of managing the flow control and main logic of the application.

Here’s a simple ASP.NET MVC controller example:

_____________________________________________________________

public class HomeController : Controller

{

public ActionResult Index()

{

// Logic to retrieve and display a list

return View();

}

[HttpGet]

public ActionResult Create()

{

// Logic to create a new data in a form

return View();

}

[HttpPost]

public ActionResult Create(HomeViewModel model)

{

// Process form submission and create a new data

// Redirect to the list or show validation errors

}

}

Views in ASP.NET MVC

Introduction to Views in MVC:

Views are a fundamental component of the ASP.NET MVC (Model-View-Controller) program that are responsible for presenting data to users. Views are used in ASP.NET MVC to construct the user interface with which users interact with a web application. Views are commonly used to present data to consumers and collect user input.

Here are some important points to remember regarding views in ASP.NET MVC:

Separation of Concerns: ASP.NET MVC encourages concern separation by splitting the application into three primary components: Model, View, and Controller. Views are responsible for rendering the user interface and should focus on presentation concerns, while the Model and Controller handle business logic and data processing, respectively.

Razor Syntax: The Razor view engine, which enables you to combine HTML with C# or VB.NET code to dynamically build the content that will be transmitted to the user’s browser, is commonly used to create views in ASP.NET MVC. The @ sign in Razor syntax is used to incorporate C# code inside HTML markup.

Strongly Typed Views: ASP.NET MVC views have the option to be strongly typed, which identifies them as belonging to a certain model class. This relationship makes it easier to show and work with data by enabling you to access model attributes directly in the view using Razor syntax.

Layouts: Layout pages can be used by views to define a common framework for different views inside the application. This allows you to maintain a uniform look and feel across your online application. Layout pages are often composed of the standard HTML structure, headers, footers, and navigation menus.

Partial Views: Partial views are a method of dividing large views into smaller, reusable components. They are important for developing modular and maintainable user interfaces since they may be rendered within other views.

HTML Helpers: ASP.NET MVC comes with HTML helpers that make it easier to generate forms and HTML elements inside of views. With the aid of these helpers, you may produce HTML code that complies with the model and routing setup of the application.

ViewModels: Apart from models, you can also construct view models, which are objects for data transfer that are specifically designed to meet the requirements of a view. View models give the view all the information it needs to render by combining data from one or more models.

View Engines: While Razor is the most generally used view engine in ASP.NET MVC, you can also utilize Web Forms view engine and custom view engines depending on your tastes and requirements.

ViewBag and ViewData: ViewBag and ViewData are two techniques for transferring information from the controller to the view. ViewData is a dictionary-like container, while ViewBag is a dynamic object. They are often used when you wish to transmit data to the view that is not included in the model.

In summary, views in ASP.NET MVC are in charge of displaying a web application’s user interface. Their dynamic content is rendered using a blend of Razor and HTML syntax. They support partial views for modularization, layout pages for consistency, and strongly typing. In an ASP.NET MVC application, views are essential to achieving a clear separation of concerns.

Model in ASP.NET MVC


Introduction to Model in MVC:

In the Model-View-Controller (MVC) architectural pattern, the “Model” is the core component responsible for representing the application’s data and implementing the business logic required for managing and processing that data. The Model plays a crucial role in separating concerns and organizing the structure of an application. It encapsulates the data and provides methods and operations to manipulate and interact with it. By doing so, the Model ensures that the data remains independent of the user interface and the user actions. This separation allows for easier maintenance, scalability, and reusability of the application. Additionally, the Model is responsible for enforcing data integrity and implementing validation rules to ensure the consistency and correctness of the data. It acts as the central hub for data-related operations, such as retrieving, updating, and deleting data, as well as performing complex calculations and transformations. Overall, the Model in MVC serves as the backbone of the application, providing a reliable and efficient way to manage and process data while promoting a clean and organized architecture.

Here is a detailed explanation of the Model in MVC in several areas:

Business Logic: The business logic of the application is contained in the Model. It includes all of the procedures, algorithms, and rules that control the handling and modification of data. It carries out any necessary computations or data transformations, enforces validation, and guarantees data integrity.

Data Management: The data in the application is managed by the Model. Numerous sources, including databases, web services, external APIs, and in-memory data structures, may provide this data. The logic for retrieving, storing, and manipulating data from many sources is encapsulated in the Model.

Data Representation: You specify the data structure that the application uses in the Model. Creating classes or objects to represent entities in the domain of your application is usually required for this. Database tables, data transfer objects (DTOs), and domain entities are frequently mapped to these types.

Data Access: Working with databases and other data storage systems is part of the data access that the Model manages. To carry out tasks like inserting, updating, deleting, and querying data, it interfaces with the database. Object-Relational Mapping (ORM) frameworks like Entity Framework or libraries like Hibernate are utilized in many contemporary MVC applications to make data access easier.

Data Validation: The Model is in charge of verifying that the data complies with certain limitations and guidelines. To guarantee data quality and integrity, data validation techniques can include custom validation algorithms, data type validation, and mandatory field checks.

Separation of Concerns: The separation of concerns is a fundamental principle of MVC. Both the View and the Controller are separated from the Model. This separation enables each component to be developed, tested, and maintained independently, making the program more modular and maintainable.

Event Handling: The Model can incorporate event handling in particular instances. When data changes, it can alert other portions of the program (Views and Controllers). This approach is also known as the “observable” or “publish-subscribe” pattern.

Testing: Since models include the essential data operations and business logic, they are very testable. Independent of the user interface, you can create unit tests to verify that your business logic and data manipulation are sound. An important benefit in software development is this.

UI-Agnostic: Models are UI-agnostic, which means they don’t care how the user interacts with the data or how it is presented to them. Because of this separation, you may modify the user interface without changing the business logic or underlying data.

In summary, the Model in the Model-View-Controller (MVC) architectural pattern is the crucial component responsible for representing and managing the data and business logic of an application. It plays a pivotal role in the development of robust, maintainable, and organized software by effectively separating concerns and fostering a modular architecture. By encapsulating the data and implementing the necessary business rules, the Model ensures the integrity and consistency of the application’s data. It acts as the central hub for data manipulation, validation, and storage, providing a reliable foundation for the overall functionality of the software. Additionally, the Model facilitates the decoupling of the user interface (View) and the application logic (Controller), enabling independent development and testing of these components. Through its role in the MVC pattern, the Model promotes code reusability, scalability, and maintainability, ultimately contributing to the overall success of the software development process.

Setting up a Basic MVC Project in ASP.NET

There are various phases involved in creating a simple ASP.NET MVC (Model-View-Controller) project. Model-View-Controller (MVC) is a design pattern that divides an application into three interrelated components: Models, Views, and Controllers. This split aids in code organisation and maintainability. Here’s a step-by-step tutorial for creating a simple ASP.NET MVC project:

step 1 – Install Visual Studio:

Install Visual Studio, a popular programming environment for ASP.NET apps, if you haven’t already. The free Community edition can be downloaded from the Microsoft website.

step 2 – Create a New Project:

Make a new ASP.NET project first:

Launch Microsoft Visual Studio.

Click on “File” > “New” > “Project…”

Choose “ASP.NET Web Application” from the “Create a new project” window, then click “Next.”

step 3 – Choose Project Template:

Choose the “ASP.NET Core Web Application” template from the “New Project” dialog box. You have the option to select the target framework, name your project, and designate a location. Press “Create.”

step 4 – Configure Your Project:

Click “Create a new ASP.NET framework web application” in the dialog box.

Choose the project template “Web Application (Model-View-Controller)”.

Select “Create” from the menu.

step 5 – Understanding the Framework:

Controllers: Your controller classes are stored in this folder.

Models: This is the location for your model classes.

Views: The views (HTML templates) for your application are stored in this folder.

wwwroot: This is the location for static files such as CSS, JavaScript, and pictures.

step 6 – Create a New Model Class:

Create a new class in your MVC project for your model. You may do this by right-clicking on the “Models” folder in Visual Studio (or your preferred IDE) and selecting “Add” > “Class.” or “using ado.net data entity model method”.

step 7 – Create a Controller:

You may add a new controller to your MVC project by right-clicking the Controllers folder, selecting “Add” > “Controller,” and then following the wizard to construct a basic controller with actions.

step 8 – Create Views:

Create subfolders for your controller actions in your MVC project’s Views folder (e.g., “Home” for the HomeController). Create Razor views (.cshtml files) for your activities within these subfolders.

step 9 – Configure Routing:

The Startup.cs file configures the default routing for ASP.NET MVC. In the Configure function, you can map URLs to controller actions by configuring routes.

step 10 – Run the Program:

Use the Debug menu or press F5 to launch your application. This will start a web server and show your application on a web browser.

step 11 – Test Your MVC Application:

By visiting the relevant URLs, you can access the actions that you created. As an illustration, if your HomeController has an action called “Index,” you can get it at http://localhost:port/Home/Index.

A simple ASP.NET MVC application setup is shown here. Models, controllers, views, and more intricate routing can all be added to this base as your project requires it. To get additional functionality, you can combine different libraries and frameworks with Entity Framework and utilize it to work with databases.

MVC framework in ASP.NET

Introduction to MVC (Model-View-Controller) in ASP.NET:

MVC (Model-View-Controller) is a common architectural paradigm for constructing online applications in ASP.NET. It provides a structured and organized approach to web application development by dividing the application into three interconnected components: the Model, the View, and the Controller. This separation of concerns makes the codebase easier to manage and maintain, promotes code reusability, and improves overall application adaptability.

Let’s take a closer look at each component:

Model: The Model represents the data and business logic of the application. It contains the data on which your application runs as well as the rules that govern that data. It is in charge of retrieving and storing data from a database or other data sources, as well as carrying out data-related tasks.

View: The View is in charge of rendering the user interface and displaying data to the user. Views in an ASP.NET MVC application are normally built in HTML, but they can also contain embedded code (Razor syntax) to show dynamic content. Views are retained as independent files, making the display layer easier to handle.

Controller: The Controller functions as a go-between for the Model and the View. It processes user requests, interacts with the Model to retrieve or change data, and then selects the appropriate View to show the response to the user. It contains the application’s logic for handling HTTP requests and is the starting point for the majority of user interactions.

Main advantages and characteristics of ASP.NET MVC use:

Separation of Concerns: MVC requires a distinct division of responsibilities, which facilitates application understanding, maintenance, and expansion. Developers are able to work independently on various components because to this separation.

Reusability: MVC improves code reusability and reduces redundancy by allowing models, views, and controllers to be often reused in other application components.

Testability: MVC allows for independent unit testing of each component, which improves code quality and facilitates more effective debugging.

Flexibility: MVC enables developers to add to and modify some areas of the program without compromising the functionality of the other sections. It is now simpler to adjust to evolving needs as a result.

Support for Multiple View Engines: ASP.NET MVC offers flexibility in how you render your views by supporting a number of view engines, such as Razor and Web Forms.

 

Usually, you use one of the MVC project templates to create a project in Visual Studio to begin working with MVC in ASP.NET. Models, views, and controllers are all built up in the fundamental framework of your application by using these templates. After that, you may construct on top of this base by defining your views for data display, writing controller actions for user requests, and defining your data models.

In conclusion, MVC is an effective architectural pattern that encourages the creation of web applications in ASP.NET using an organized methodology. Because of its many benefits for code organization, maintainability, and testability, it is a well-liked option among developers creating ASP.NET web applications.

Learn SQL online

Learn SQL online

In our increasingly digital economy, SQL abilities are highly valued. The demand for skilled experts to analyse all that data is increasing along with the number of companies gathering customer information.

An average learner should be able to acquire the fundamentals of SQL and begin using SQL databases in roughly two to three weeks. But you’ll need to become pretty fluent with them before you can start employing them successfully in everyday situations, and that takes time.

SQL is not a conventional programming language, where you would create a series of instructions that would be executed in a specific order. Instead, SQL is a “declarative” language, which means that when you write a query for it, you declare the data you want to get as a result but don’t specify how you want to get it.

SQL is commonly used to create, search for, change, and delete database entries. The more time you invest as a SQL practitioner, the more efficiently and creatively you can use the platform to find the answers your organisation need from the sea of data that is now available.

As we switch between applications, websites, and social media platforms every day, we leave a data trail that is mined by businesses for a variety of purposes. The lack of data analysts, however, renders raw data meaningless.

These experts organise and examine massive data collections using programming languages like SQL. They can then turn this information and correlations into business insights, which in turn can aid organisations in expanding their operations. Every second that goes by, this mountain of data gets bigger, and so does the need for SQL experts. That is the reason why SQL is so common and popular.

SQL is one of the most widely used programming languages in the world. It is used in a range of professions, such as Database administration, Data science, Software engineering, Business analytics and Journalism.

SQL proficiency is required for anyone who deals with data. This language is used by many domains and disciplines to communicate with relational databases.

SQL’s versatility is intended to allow you to query a database in a variety of ways using English-based commands. Because SQL is the most commonly used database language, practically every organisation that needs to store relational data, including big firms like Facebook, Amazon, Google, Uber, Netflix and etc rely on SQL.

SQL is utilised in many different sectors and professions. SQL is still a popular choice for software applications today because it is used by many relational database management systems. SQL offers a wide range of professional applications due to its adaptability and flexibility.

Most programming languages are only used for programming. SQL, on the other hand, is unusual in that it has applications that go beyond standard programming. SQL is used by those in sales and marketing to conduct queries on datasets, which allows them to recognise sales trends and track the success of various marketing campaigns. SQL also has uses in the finance sector. SQL is used by financial analysts to sort through vast amounts of financial data in order to save time. SQL is handy for dealing with vast amounts of structured data.

Top Reasons to Learn SQL:

SQL

  • is simple to learn.
  • is an effective troubleshooting tool.
  • is incredibly flexible and standardised.
  • makes it easier to mine your data.
  • makes it simple to combine data sets from many sources.
  • can handle enormous data sets.
  • puts important information at your fingertips.
  • demand is at an all-time high.
  • developers earn a good living.

If you want to learn SQL, the good news is that there are currently a variety of in-person and online learning alternatives accessible for learners of all levels. We have a Training Centre in Karaikudi for people who like to study in a classroom setting. Furthermore, for individuals who prefer virtual learning, we provide online SQL courses, which are a terrific option. All courses include live tuition from a SQL professional.

Data loss can be catastrophic, potentially resulting in financial losses, legal ramifications, and loss of trust among users. Backup solutions ensure data integrity by creating copies of essential information at regular intervals. In case of data corruption or loss, these backups act as recovery points, enabling developers to restore the application to a previous state.

  1. Disaster Recovery

Natural disasters, hardware failures, or even simple human errors can disrupt the availability of applications. Data backup plays a pivotal role in disaster recovery, allowing organizations to rebuild their applications and services with minimal downtime.

  1. Security Measures

In the digital age, cybersecurity is of extreme importance. Regular backups can mitigate the damage caused by ransomware attacks or other malicious activities. If a system is compromised, having a backup ensures that attackers can’t hold the data hostage.

  1. Testing and Development

Backed-up data can be a valuable resource for testing and development purposes. Developers can use copies of real data to create realistic testing scenarios or build new features without risking the integrity of the production environment.

  1. Compliance and Regulations

Many industries are bound by regulations that mandate data retention and security. Backup strategies that align with these regulations help organizations avoid penalties and legal complications.

Workshop Insights: Data Backup in .NET

As the “.NET One Day Workshop” progressed, the segment on data persistence and backup resonated deeply with the participants. The workshop shed light on how the .NET framework offers several mechanisms to implement effective data backup strategies:

  1. Database Backups

Databases are at the heart of most applications, housing critical data. .NET supports various database systems like SQL Server, MySQL, and PostgreSQL. These databases often provide built-in mechanisms for automated backups and recovery.

  1. Version Control

While version control systems like Git are primarily associated with source code management, they indirectly contribute to data backup. By maintaining a history of code changes, version control systems provide a level of data recovery in case of accidental code loss or errors.

  1. Cloud Solutions

Cloud platforms offer scalable and reliable options for data backup. Azure Backup, for instance, provides services for backing up data, applications, and virtual machines directly from the Azure portal.

  1. Application State Management

In web applications, maintaining the application’s state is crucial for user experience. .NET offers techniques to persist user sessions and application states, ensuring a seamless experience even after server restarts.

Areas, Partial Views and Child Actions in ASP.NET MVC

Developers may organise their applications, build modular components, and improve code reuse by using Areas, Partial Views, and Child Actions in ASP.NET MVC. Let’s examine each of these ideas and how to employ them successfully:

Areas in ASP.NET MVC:

A huge ASP.NET MVC application can be divided up into manageable portions using areas. Within the application, each region represents a different functional area. You may designate several locations for the administration, user dashboards, or public-facing pages, for instance.

Right-click the project, pick “Add,” and then select “Area” from the context menu to create an area. Following that, you can give the region a name and designate a folder structure for it. It will have separate folders for its controllers, views, and models.

Areas facilitate better concern segregation and simplify the upkeep of sophisticated programmes.

Partial Views in ASP.NET MVC:

In order to display a portion of HTML content and C# code in various views throughout the application, partial views are reusable components.

You can build a partial view by adding a new view to the “Views” folder (or a subfolder) and naming it something like “_PartialView.cshtml.”

You can render a partial view within another view using the @Html.Partial or @Html.RenderPartial methods, passing the partial view’s name as an argument.

Child Actions in ASP.NET MVC:

Child actions are controller methods that return partial views. They come in handy when you need to render different elements of a view independently.

To create a child action, define a method in a controller that returns a PartialViewResult. You can use the ChildActionOnly attribute to ensure that the method can only be called as a child action and not directly as an HTTP request.

In your main view, you can call the child action using the @Html.Action or @Html.RenderAction methods, passing the name of the child action and any required parameters.

Advantages of utilising areas, partial views, and child actions

Utilizing areas, partial views, and child actions in ASP.NET MVC provides several advantages that can significantly enhance the development process and improve the overall architecture of your application. Here are some key benefits of using these features:

Modularity and Reusability:

Areas allow you to divide a large application into smaller functional sections, promoting modularity and separation of concerns. Each area can have its own set of controllers, views, and models, making it easier to manage and maintain specific features.

Partial views encapsulate reusable components, such as navigation bars, headers, footers, or widgets. Once created, you can include them in multiple views across the application, reducing duplication of code and promoting reusability.

Organization and Maintainability:

By structuring your application with areas, you create a clear organization that improves code maintainability and makes it easier for developers to navigate and understand the application’s structure.

Partial views and child actions help to decompose complex views into smaller, manageable components. This separation of concerns leads to cleaner code and makes it easier to maintain and update specific parts of a page independently.

Code Separation and Readability:

Areas encourage the separation of different functional parts of the application, reducing code coupling and increasing code readability.

Partial views and child actions enable you to separate the presentation logic from the main view, enhancing the readability and maintainability of the code.

Code Reusability and DRY Principle:

Areas, partial views, and child actions promote the “Don’t Repeat Yourself” (DRY) principle, allowing you to reuse code across different areas or views.

Instead of duplicating code for common UI components, you can create partial views once and then use them in multiple views, reducing development effort and avoiding inconsistencies.

Performance Optimization:

By utilizing child actions, you can optimize the rendering of complex views by rendering specific parts of a page separately, reducing the overall load time and enhancing user experience.

Partial views can help optimize rendering performance by allowing you to cache the output of specific components that are unlikely to change frequently.

Enhanced Testing and Debugging:

The use of areas allows for better isolation and targeted testing of specific functional sections, making unit testing and debugging more focused and effective.

Partial views and child actions can be tested independently, making it easier to verify the correctness of individual components.

In summary,, the strategic use of areas, partial views, and child actions in ASP.NET MVC not only fosters reusability, performance optimisation, and increased testing capabilities but also enhances code organisation and maintainability. Building scalable, stable, and modular web applications that are simpler to maintain and develop over time is made possible by these qualities.

Example

Consider the following scenario:

Assume you have an e-commerce site with distinct sections for the product catalogue and the user dashboard. You can construct partial views for common elements such as navigation, headers, and footers and then reuse them across several views inside each section. You can also call a child action in the header partial view to display the user’s shopping basket.

You may improve the flexibility and maintainability of your ASP.NET MVC application by efficiently utilising Areas, Partial Views, and Child Actions, resulting in a more organised and efficient development process.

Routing in ASP.NET

Routing in ASP.NET is the process of sending HTTP requests to the appropriate controller. Whether a request should be forwarded to the controller for processing or not is up to the MVC middleware. This choice is made by the middleware based on the URL and some configuration data.

In other words, routing in ASP.NET is a mechanism that allows you to define URL patterns and map them to specific resources or handlers in your web application. It enables you to create clean, user-friendly URLs that are more meaningful and descriptive than traditional query-string based URLs.

Routing is an essential part of the ASP.NET MVC (Model-View-Controller) framework and the newer ASP.NET Core framework, although the concept remains similar across both technologies.

Routing’s main goal is to separate your web application’s physical file structure from its URL structure. In the past, URLs in web applications were linked to particular physical server files (for example, a particular.aspx page). However, routing gives you more flexibility when defining the URLs for your web application since it allows you to specify URL patterns and link them to controllers and actions (in MVC) or endpoints (in ASP.NET Core).

To address various scenarios and requirements, ASP.NET MVC supports a number of different forms of routing. The primary routing types that ASP.NET MVC supports are listed below:

Conventional Routing: In ASP.NET MVC, conventional routing is the default routing method. The mapping of URL segments to names of controller and action method uses a pattern-based technique. A URL pattern typically looks like this: “controller/action/id,” where “controller” and “action” stand in for the names of the controller and action method, respectively. It is possible to omit the “id” parameter.

Here’s a basic example of routing in ASP.NET MVC:

// In the RouteConfig.cs file (MVC)
public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);
    routes.MapRoute(
        name: “Default”,
        url: “{controller}/{action}/{id}”,
        defaults: new {controller = “Home”, action = “Index”, id = UrlParameter.Optional }
    );
}

In this example, a default route is defined with a pattern like “{controller}/{action}/{id}”. When a user visits a URL like “example.com/Home/Index”, the routing system will map it to the “Index” action method in the “HomeController” within the MVC application. The “id” parameter is optional and can be omitted in the URL.

ASP.NET Core uses a similar concept of routing, but the syntax and configuration are slightly different. Here’s a basic example of routing in ASP.NET Core:

// In the Startup.cs file (ASP.NET Core)
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // Other middleware configurations…
    app.UseRouting();
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: “default”,
            pattern: “{controller=Home}/{action=Index}/{id?}”
        );
    });
}

In this example, the UseRouting() method is called to enable routing, and then MapControllerRoute() is used to define the default route pattern.

Routing plays a crucial role in creating clean and SEO-friendly URLs, improving the maintainability of your web application, and supporting more structured and organized code through the proper separation of concerns.

Attribute Routing: Using attributes, you may build routes directly on the controller and action methods. This method gives you more fine-grained control over single action routing and allows you to build unique routes for individual actions. When you have non-conventional URL patterns or want more descriptive URLs, attribute routing comes in handy.

In ASP.NET MVC, here’s an example of attribute routing:

// Controller with attribute routing
[RoutePrefix(“products”)]
public class ProductController : Controller
{
    [Route(“”)]
    public ActionResult Index()
    {
        // Action logic
    }
    [Route(“{id}”)]
    public ActionResult Details(int id)
    {
        // Action logic
    }
}

Area Routing: Areas are used in ASP.NET MVC to partition related portions of a web application into different modules. Controllers, views, and models can be customised for each region. Area-specific routing can be used with areas to control routes inside that specified area. When dealing with large and complex applications, this helps to maintain clean and organised code.

Custom Route Constraints: Custom route constraints let you specify extra requirements that a route must meet in order to be accepted as a match. Implementing the IRouteConstraint interface enables you to create unique route constraints. For instance, you can build a custom constraint to guarantee that the “id” argument adheres to a particular format or fits within a given range.

Catch-All Routes: Any URL that doesn’t match one of the other defined routes is matched using catch-all routes. When dealing with specific URL patterns that don’t suit the typical route patterns, this is useful.

With these multiple routing systems in ASP.NET MVC, you may handle a variety of URL patterns, create custom routes, and set up your application’s URLs anyway you see fit.

Three Tier Architecture in MVC

Three Tier (Three Layer) Architecture

With a three-layer design, the project is divided into three layers: the user interface layer, the business layer, and the data layer (database), where we divide the UI, logic, and data into three groups. If a user wants to switch the user interface from a Windows computer to a smartphone, he or she simply needs to alter the UI layer; all other layers are unaffected. Like this, if a user wishes to change a database, he simply needs to update the data layer; everything else stays the same.

The widely used three-tier (or three-layer) architecture is a way to organise the codebase. This architecture divides the codebase into three distinct levels, each with a unique set of duties:

Presentation layer: This is the application’s user interface, which shows the user the features and data of the programme.

Business logic (or Application) layer: The business logic that powers the application’s essential features is contained in this layer. as processing the data moving between the other two layers and making judgements, calculations, and evaluations.

Data access layer (or Data) layer: To save and recover application data, this layer communicates with databases.

Advantages of using three-tier architecture are:

Accelerated development: Reducing product time to market and enabling developers to use the most current tools and layer appropriate languages.

Improved scalability:  By deploying apps on many levels, each tier may always be scaled separately.

Improved Reliability: By using several tiers, you may execute additional components of your application on other servers and employ results that have been cached to improve reliability and availability.

Enhance security: By using a well-designed application layer as a private firewall to help avoid receptive weaknesses like SQL injection.

The package of different layers is as follows.

  • Presentation Layer – controller package
  • Business Logic Layer – service package
  • Data Access Layer – repository package 

Three Layer Architecture using MVC Sample:

Create an empty MVC web application project with Project name “WebApp” and solution name “TLA”. This WebApp project is the presentation layer.

In Solution TLA, add a new project to create business logic à Class library (.net framewok) à name the project as BusinessLayer.

Again, in Solution TLA, add a new project to create data access à Class library (.net framewok) à name the project as DataBaseLayer.
Add BusinessLayer & DataBaseLayer as reference in “WebApp”.

Add BusinessLayer as reference in “DataBaseLayer”.

In sql server explorer, add a new database with name “MYDB” and create a table with name “Registration”.

CREATE TABLE [dbo].[Registration](
[RegId] [int] IDENTITY(1,1) NOT NULL,
[FullName] varchar NULL,
[Address] varchar NULL,
[Gender] varchar NULL,
[City] varchar NULL,
[DoB] [date] NULL,
[Cno] varchar NULL,
PRIMARY KEY CLUSTERED ([RegId] ASC)

In “DataBaseLayer”, add the model file using “ado.net entity data model”.

Once model is created, copy the connection string from app.config of “DataBaseLayer” and paste it in web.config of “WebApp”.

In “BusinessLayer”, create a class file with name “RegistrationModel” and replace with below snippet.

public class RegistrationModel
{
public int RegId { get; set; }
public string FullName { get; set; }
public string Address { get; set; }
public string Gender { get; set; }
public string City { get; set; }
public Nullable DoB { get; set; }
public string Cno { get; set; }
}

In “DataBaseLayer”, add a new folder with name “DBOperation”, in it, add a class file with name “ManageRegistration” and replace with below snippet.

public class ManageRegistration
{
public void AddReg(RegistrationModel regModel)
{
using (var DB = new MYDBEntities())
{
Registration Reg = new Registration()
{
FullName = regModel.FullName,
Address = regModel.Address,
Gender = regModel.Gender,
City = regModel.City,
DoB = regModel.DoB,
Cno = regModel.Cno
};
DB.Registrations.Add(Reg);
DB.SaveChanges();
}
}
}

Then add EntityFramework.dll and EntityFramework.SqlServer.dll references in “WebApp”.

So now the business layer and data layer has been completely created.

Now, in WebApp (i. e. in presentation layer), add a new controller with name “Home controller” and replace with below snippet.

public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
ManageRegistration ManageReg = new ManageRegistration();
[HttpPost]
public void AddReg(FormCollection Form)
{
RegistrationModel registrationModel = new RegistrationModel()
{
FullName = Form["txtName"],
Address = Form["txtAddress"],
Gender = Form["rdbGender"],
City = Form["txtCity"],
DoB = Convert.ToDateTime(Form["txtDoB"]),
Cno = Form["txtCno"]
};
ManageReg.AddReg(registrationModel);
Response.Write("Saved");
}
}

Add index view with empty without model and put the below html and ajax snippet in it

Run the program

Solid Principles in C#.net

In C#, the SOLID principles are a set of guidelines that help developers design software that is modular, maintainable, and extensible. SOLID is an acronym that stands for:

S – Single Responsibility Principle (SRP)

O – Open-Closed Principle (OCP)

L – Liskov Substitution Principle (LSP)

I – Interface Segregation Principle (ISP)

D – Dependency Inversion Principle (DIP)

Single Responsibility Principle (SRP):

A class should have only one reason to change. It states that a class should have only one responsibility or job. This principle helps to keep classes focused, maintainable, and easier to understand.

public interface INotificationService
{
void SendNotification(string message);
}
public class EmailNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an email notification
}
}
public class SMSNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an SMS notification
}
}
public class NotificationSender
{
private readonly INotificationService _notificationService;
public NotificationSender(INotificationService notificationService) { _notificationService = notificationService; } public void SendNotification(string message) { _notificationService.SendNotification(message); }
}

In this example, the FileManager class has the responsibility of reading and saving files, while the FileParser class is responsible for parsing files. Each class has a single responsibility, making it easier to understand and maintain.

Open-Closed Principle (OCP):

Software entities (classes, modules, functions, etc.) should be open for extension but closed for modification. This principle encourages designing modules that can be extended without modifying their existing code, reducing the risk of introducing bugs and making it easier to add new features.

public abstract class Shape
{
public abstract double CalculateArea();
}
public class Rectangle : Shape
{
public double Width { get; set; }
public double Height { get; set; }
public override double CalculateArea() { return Width * Height; }
}
public class Circle : Shape
{
public double Radius { get; set; }
public override double CalculateArea() { return Math.PI * Radius * Radius; }
}

In this example, the Shape class is open for extension, as new shapes can be added by creating new subclasses of Shape. The existing code is closed for modification, as the Shape class and its existing subclasses do not need to be changed when adding new shapes.

Liskov Substitution Principle (LSP):

Objects of a superclass should be able to be replaced with objects of their subclass without breaking the behavior of the system. In other words, derived classes should be substitutable for their base classes, and they should honor the contracts defined by the base class.

public class Vehicle
{
public virtual void Start()
{
Console.WriteLine(“Starting the vehicle”);
}
}
public class Car : Vehicle
{
public override void Start()
{
Console.WriteLine(“Starting the car”);
}
}
public class Motorcycle : Vehicle
{
public override void Start()
{
Console.WriteLine(“Starting the motorcycle”);
}
}

In this example, the Car and Motorcycle classes are subclasses of Vehicle, and they can be substituted for Vehicle without breaking the behavior of the system. The Start method is overridden in each subclass, providing specific implementations for starting a car and starting a motorcycle.

Interface Segregation Principle (ISP):

Clients should not be forced to depend on interfaces they do not use. This principle encourages the creation of small, specific interfaces instead of large general-purpose interfaces. It helps to avoid forcing clients to implement methods they don’t need and promotes decoupling and flexibility.

public interface IOrder
{
void ProcessOrder();
}
public interface IShipping
{
void ShipOrder();
}
public class OnlineOrder : IOrder, IShipping
{
public void ProcessOrder()
{
Console.WriteLine(“Processing online order”);
}
public void ShipOrder() { Console.WriteLine("Shipping online order"); }
}
public class OfflineOrder : IOrder
{
public void ProcessOrder()
{
Console.WriteLine(“Processing offline order”);
}
}

In this example, we have two interfaces: IOrder and IShipping. The OnlineOrder class implements both interfaces, as it can process an order and ship it. The OfflineOrder class only implements the IOrder interface because it doesn’t involve shipping. This segregation of interfaces ensures that classes only depend on the methods they actually need.

Dependency Inversion Principle (DIP):

High-level modules should not depend on low-level modules; both should depend on abstractions. Abstractions should not depend on details; details should depend on abstractions. This principle promotes loose coupling between modules, promotes modular design, and enables easier testing and maintainability.

public interface INotificationService
{
void SendNotification(string message);
}
public class EmailNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an email notification
}
}
public class SMSNotificationService : INotificationService
{
public void SendNotification(string message)
{
// Code to send an SMS notification
}
}
public class NotificationSender
{
private readonly INotificationService _notificationService;
public NotificationSender(INotificationService notificationService) { _notificationService = notificationService; } public void SendNotification(string message) { _notificationService.SendNotification(message); }
}

In this example, the NotificationSender class depends on the INotificationService interface rather than concrete implementations. This allows different notification services to be injected at runtime, promoting loose coupling. The high-level module (NotificationSender) depends on the abstraction (INotificationService) rather than the low-level modules (EmailNotificationService, SMSNotificationService).

By adhering to these principles, developers can create code that is easier to understand, maintain, and modify, leading to more robust and scalable software systems.

C# Web API

C# Web API

Asp.net Web API is a framework that is provided by Microsoft and used to create HTTP services.

ASP.NET Web API is an easy-to-build HTTP web service. To reach a range of clients, including browsers, mobile applications, desktop applications, and IOTs.

The Asp.net web API has two layers.

 1.client layer

 2.server layer

It is accessed by a wide range of clients, including web browsers, mobile applications, and desktop applications, when the client layer makes a request to the web API to get an output response in different formats like JSON or XML.

Http Request = http://servername/apiname?id=101
Http Response = {“Name”,ABC,”Age”:”54”}

What is HTTP?  
HTTP – Hyper Text Transfer Protocol means the user gets a different device to get a request, but the output gets the same response server, also called HTTP.
HTTP Is used more than providing web page and also strong foundation for the developing API.
HTTP is a essential and pervasive protocol  

Why to choose ASP.NET Web API?

  • Web API is light weight framework for API Development
  • Web API has built-in support for standard formats like JSON and XML., and Other Formats.
  • Web API is a Content Negotiation
  • c#.net Web API maps HTTP Verbs to method names

Features of Web API

Filter: It gives filters to the web application.
Action Result: It can keep the action logos client, such as information recovery.
Routing: It makes a difference in routing through different APIs.
Controller: It gives useful capabilities to the web application.
Model: It gives the basic capabilities of the web application.  

Types of Web API in C#

  1. public
  2. partner
  3. private
  4. Composite

Public APIs 

 A public API is open and available for use by outside developers or businesses; its application, Data, will develop and offer a public API. also called public APIs or external APIs.

Partner APIs

Partner APIs can interface the internal client information system with those outside groups no other APIs are allowed. APIs are generally stronger authentication, authorization, and security machines.

private APIs

Private APIs are used by enterprises to connect system and data APIs for internal use at certain security levels.

Composite APIs

Composite APIs generally combine two or more APIs’ interdependent operations. Composite APIs sometimes improve speed and performance.

SQL Job Support in India

SQL Overview:

SQL is a database management language that includes database creation, database deletion, fetching data rows, modifying, and deleting data rows, and so on.

SQL stands for Structured Query Language, and it is a computer language used to store, manipulate, and retrieve data from relational databases. SQL was created by IBM Computer Scientists in the 1970s and was adopted as a standard by the American National Standards Institute (ANSI) in 1986 and the International Organization for Standardization (ISO) in 1987.

SQL is the industry standard for communicating with Relational Database Systems. SQL is the Standard Database Language used by all Relational Database Management Systems (RDMS) such as MySQL, MS Access, Oracle, Sybase, Informix, Postgres, and SQL Server.

Data is everything nowadays. To comprehend this, you must be familiar with data management. SQL is a language that can be used to understand databases. SQL (Structured Query Language) is the name given to a language used to communicate with databases. The SQL language can be used to edit, pull, and add information to a database. SQL is the foundation of relational databases. More information is available in our SQL online job support.

SQL is widely used because it provides the following benefits:

Users can

  • access data stored in relational database management systems.
  • describe the data.
  • define and manipulate data in a database.
  • create and delete databases and tables.
  • create views, stored procedures, and functions in a database.
  • assign permissions to tables, procedures, and views.
  • embed SQL modules, libraries, and pre-compilers within other languages.

Stored Procedure in SQL Server

  • A stored procedure is a precompiled and stored database object that contains a set of SQL statements and procedural logic that can be executed as a single unit. It can be used in a database management system to simplify complex queries and database operations. It is a prepared SQL code that you can save, so the code can be reused over and over again. Stored procedures help improve performance and security, as well as simplify the code.

Here’s a basic example of a stored procedure that accepts two input parameters and returns the sum of those two numbers:

CREATE PROCEDURE AddNumbers
@n1 INT,
@n2 INT
AS
BEGIN
SET NOCOUNT ON;
SELECT @n1 + @n2 AS ‘Sum’;
END  

In this example, CREATE PROCEDURE is used to define the name of the procedure (AddNumbers) and its input parameters (@n1 and @n2). The AS keyword is used to begin the code block for the stored procedure.

SET NOCOUNT ON is used to prevent the count of the number of rows affected by the stored procedure from being returned.

The code block then calculates the sum of the two input parameters and returns the result using the SELECT statement.

Once the stored procedure is defined, it can be executed by calling its name:

EXEC AddNumbers 2, 3;

This will return the result 5 as the sum of 2 and 3.

Stored Procedure in a Basic CRUD Operation

Now, let us have an idea about using stored procedure in a basic CRUD operation sample.

Let us create a database as follows:

Create database Company

Then create a table in the corresponding database.

CREATE TABLE Employee(
EmpCode int,
EmpName nchar(100),
EmpAge int,
EmpSal int)

Inserting data into a table: This stored procedure inserts a new employee record into a table named Employee:

CREATE PROCEDURE AddEmployee
@EmpCode int,
@EmpName nchar(100),
@EmpAge int,
@EmpSal int
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO Employee(EmpCode, EmpName, EmpAge, EmpSal)
VALUES (@EmpCode, @EmpName, @EmpAge, @EmpSal);
END

On executing the above snippet, a stored procedure to add the details in the table will be created.

Now, by calling the below query, the table will get added the following 5 datas.

EXEC AddEmployee 1, ‘TOM’, 25, 30000
EXEC AddEmployee 2, ‘RAM’, 25, 30000
EXEC AddEmployee 3, ‘RAJA’, 26, 32000
EXEC AddEmployee 4, ‘SIVA’, 26, 32000
EXEC AddEmployee 5, ‘GOPI’, 25, 30000

Retrieving data from a table: This stored procedure retrieves all the rows from a table named Employee:

CREATE PROCEDURE GetEmployees
AS
BEGIN
SET NOCOUNT ON;
SELECT * FROM Employee;
END

On executing the above snippet, a stored procedure to get the employee details from the table will be created.

Then by simply calling the below query, the datas stored in the table can be retrieved.

EXEC GetEmployees

Updating data in a table: This stored procedure updates an existing employee record in a table named Employee:

CREATE PROCEDURE UpdateEmployee
@EmpCode int,
@EmpName nchar(100),
@EmpAge int,
@EmpSal int
AS
BEGIN
SET NOCOUNT ON;
UPDATE Employee SET
EmpName = @EmpName,
EmpAge = @EmpAge,
EmpSal = @EmpSal
WHERE EmpCode = @EmpCode;
END

On executing the above snippet, a stored procedure to update the details in the table will be created.

Now, by calling the below query, the data with “EmpCode =1” in the table can be updated with new data as follows.

EXEC UpdateEmployee 1, ‘Jerry’, 26, 32000

Deleting data from a table: This stored procedure deletes an existing employee record from a table named Employee:

CREATE PROCEDURE DeleteEmployee
@EmpCode int
AS
BEGIN
SET NOCOUNT ON;
DELETE FROM Employee
WHERE EmpCode = @EmpCode;
END

On executing the above snippet, a stored procedure to delete the details in the table will be created.

Now, by calling the below query, the data with “EmpCode=1” in the table can be deleted

EXEC DeleteEmployee 1

These are just a few examples, and there are many more possibilities for what you can do with stored procedures.

SQL & C# Dot Net – Online Training in India:

SQL and DOT NET Technologies:

SQL and DOT NET are two distinct technologies that are frequently used in software development. SQL is an abbreviation for Structured Query Language, a programming language used to manage and manipulate relational databases. DOT NET is a software development framework that allows you to create and run applications on a variety of platforms, including Windows, macOS, and Linux.

SQL is widely used in relational databases such as MySQL, Oracle, and Microsoft SQL Server to manage data. SQL allows developers to use a standardised syntax to create, modify, and query databases. SQL allows for a wide range of operations, such as data insertion, deletion, modification, and retrieval. SQL is also used to analyse data, report on it, and gather business intelligence.

DOT NET is a well-known software development framework that is used to create desktop, web, and mobile applications. DOT NET provides a set of libraries, tools, and runtime environments that simplify the development, testing, and deployment of applications. DOT NET supports a variety of programming languages, including C#, F#, and Visual Basic, and it can be used to create applications for a variety of platforms, including Windows, macOS, Linux, and mobile devices.

SQL and DOT NET, when used together, can provide powerful solutions for managing and manipulating data in applications. For example, a DOT NET application can use SQL to manage its data in a relational database, making it easier to store and retrieve data. Furthermore, DOT NET includes a set of libraries and tools that make it easier to integrate with SQL databases, allowing developers to create applications that can handle large amounts of data while also supporting complex data analysis and reporting.

Future of DOT NET:

Dot Net has a broad scope, and its future appears bright. Dot net is the future of Windows and other operating systems development.

“c++” is the result of the evolution of “c.” C++’s evolution continues. C# is a modern, dependable, and robust programming language. C#.net works with the Microsoft.NET framework. Delegates, Interface, and Abstraction are just a few of the cool features that have propelled C#.net to the top of the world. C# has inherited the best characteristics of its forefathers, including C, C++, and Java. Because of their best features, C# continues to be the solution provider for various hypothetical problems. C#.net was derived from various object-oriented programming extracts.

OOPs Concepts

OOPs Concepts:

It is a programming paradigm that focuses on the use of objects to represent data and behaviors in software applications.

It is based on the concept of “classes” and “objects”.

The main principles of OOPs are Encapsulation, Inheritance, Polymorphism & Abstraction

Classes:
A class is a blueprint for creating objects. It defines the properties and methods that an object of that class will have. For example, a class called “Person” might have properties such as “name”, “age”, and “gender”, and methods such as “walk” and “talk”.

In C#, classes are a fundamental building block of object-oriented programming (OOP). A class is a blueprint or a template that defines the structure and behaviour of a particular type of object.

Here’s an example of a class in C#:

public class Person

{

    public string Name { get; set; }

    public int Age { get; set; }

    public string Address { get; set; }

    public void PrintDetails()

    {

        Console.WriteLine($”Name: {Name}, Age: {Age}, Address: {Address}”);

    }

}

In this example, we have defined a class called Person that has three properties: Name, Age, and Address. These properties are defined using auto-implemented properties, which are shorthand for defining a private field and public getter/setter methods.

The PrintDetails method is a behaviour of the Person class. It is a public method that can be called on an instance of the Person class to print out the person’s details.

To create an instance of the Person class and set its properties, we can do the following:

Person person = new Person();

person.Name = “John”;

person.Age = 30;

person.Address = “123 Main St.”;

And to call the PrintDetails method on the person instance:

person.PrintDetails(); // Output: Name: John, Age: 30, Address: 123 Main St.

In this way, classes in C# allow us to define the structure and behaviour of our objects and create instances of those objects with specific properties and methods.

Objects:

An object is an instance of a class. It represents a specific instance of the class and has its own set of values for the properties defined by the class. For example, an object created from the “Person” class might have a name of “John”, an age of 25, and a gender of “Male”.

In C#, an object is an instance of a class. When we create an instance of a class using the new keyword, we are creating an object of that class.

Here’s an example of creating an object of the Person class we defined earlier:

Person person = new Person();

In this example, person is an object of the Person class. We can access its properties and call its methods using the dot notation:

person.Name = “John”;

person.Age = 30;

person.Address = “123 Main St.”;

person.PrintDetails(); // Output: Name: John, Age: 30, Address: 123 Main St.

Each object of a class has its own set of properties and can have different values for those properties. For example, we can create another object of the Person class with different values for its properties:

Person person2 = new Person();

person2.Name = “Jane”;

person2.Age = 25;

person2.Address = “456 Elm St.”;

person2.PrintDetails(); // Output: Name: Jane, Age: 25, Address: 456 Elm St.

In this way, objects in C# allow us to create multiple instances of a class, each with its own set of properties and values. We can use these objects to represent real-world entities or concepts in our programs and manipulate them by calling their methods and accessing their properties.

Encapsulation:

One of the key features of OOP is encapsulation, which is the concept of bundling data and methods that operate on that data within a single unit. This makes it easier to manage and maintain the code and helps to prevent the data from being accessed or modified by code outside of the class.

Encapsulation is one of the core principles of object-oriented programming (OOP) and refers to the practice of bundling data and the methods that operate on that data within a single unit, called a class, and restricting access to the inner workings of that class from the outside world.

In C#, encapsulation is achieved through access modifiers, which are keywords that determine the level of access that other code has to a particular class member (i.e., fields, properties, methods). C# provides four access modifiers:

public: The member is accessible from any code.

private: The member is accessible only within the same class.

protected: The member is accessible within the same class and any derived classes.

internal: The member is accessible within the same assembly.

Here’s an example of using encapsulation to hide the implementation details of a Person class:

public class Person

{

    private string name;

    private int age;

    private string address;

    public string Name

    {

        get { return name; }

        set { name = value; }

    }

    public int Age

    {

        get { return age; }

        set { age = value; }

    }

    public string Address

    {

        get { return address; }

        set { address = value; }

    }

    public void PrintDetails()

    {

        Console.WriteLine($”Name: {Name}, Age: {Age}, Address: {Address}”);

    }

}

In this example, the fields name, age, and address are marked as private, which means they can only be accessed from within the Person class. However, we’ve also defined public properties Name, Age, and Address that provide access to these fields from outside the class. By using properties, we can control the access to the fields and add logic to the getter/setter methods if necessary.

The PrintDetails method is also a public method that can be called from outside the class to print out the person’s details. However, it does not provide direct access to the internal fields.

By using encapsulation in this way, we can ensure that the internal state of a class is not accidentally or intentionally modified from outside the class, and that changes to the internal implementation of the class do not affect the external code that uses it.

Inheritance:

Inheritance allows a new class to be based on an existing class, inheriting its properties and methods. This can save time and effort in development, as the new class can reuse the code of the existing class.

Inheritance is another core principle of object-oriented programming (OOP) and refers to the ability of a class to inherit properties and behaviours from a parent class. In C#, inheritance is achieved through the : symbol followed by the name of the parent class.

Here’s an example of using inheritance to create a Student class that inherits from the Person class:

public class Student : Person

{

    public int GradeLevel { get; set; }

    public string SchoolName { get; set; }

    public void PrintSchoolInfo()

    {

        Console.WriteLine($”School: {SchoolName}, Grade: {GradeLevel}”);

    }

}

In this example, the Student class inherits from the Person class using the: symbol. This means that the Student class has access to all of the public and protected members of the Person class, including its fields, properties, and methods.

In addition to the inherited members, the Student class defines two new properties, GradeLevel and SchoolName, and a new method, PrintSchoolInfo.

We can create an object of the Student class and set its properties just like we did with the Person class:

Student student = new Student();

student.Name = “John”;

student.Age = 15;

student.Address = “123 Main St.”;

student.GradeLevel = 9;

student.SchoolName = “High School”;

And we can call methods from both the Person and Student classes on the student object:

student.PrintDetails(); // Output: Name: John, Age: 15, Address: 123 Main St.

student.PrintSchoolInfo(); // Output: School: High School, Grade: 9

By using inheritance in this way, we can reuse code from existing classes and create more specialized classes that add new properties and behaviours on top of the existing ones. It also allows us to create a hierarchy of related classes, where each class builds on the properties and behaviours of the classes above it in the hierarchy.

Polymorphism:

Polymorphism allows objects of different classes to be treated as if they are of the same class, by using a common interface. This makes it easier to write code that works with multiple objects, as the code can be written to work with the interface rather than the specific classes.

Polymorphism is another core principle of object-oriented programming (OOP) and refers to the ability of objects of different classes to be used interchangeably in the same context. In C#, polymorphism is achieved through inheritance and interfaces.

There are two main types of polymorphism in C#: compile-time polymorphism and runtime polymorphism.

Compile-time polymorphism, also known as method overloading, refers to the ability of a method to have multiple definitions with different parameter lists. The correct method to call is determined at compile time based on the number and types of arguments passed to the method.

Here’s an example of method overloading in C#:

public class Calculator

{

    public int Add(int x, int y)

    {

        return x + y;

    }

    public float Add(float x, float y)

    {

        return x + y;

    }

}

In this example, the Calculator class defines two Add methods with different parameter types (int and float). Depending on the arguments passed to the Add method, the compiler will choose the appropriate overload at compile time.

Runtime polymorphism, also known as method overriding, refers to the ability of a subclass to provide a different implementation of a method that is already defined in its parent class. The correct method to call is determined at runtime based on the type of the object that the method is called on.

Here’s an example of method overriding in C#:

public class Animal

{

    public virtual void MakeSound()

    {

        Console.WriteLine(“The animal makes a sound.”);

    }

}

public class Dog : Animal

{

    public override void MakeSound()

    {

        Console.WriteLine(“The dog barks.”);

    }

}

In this example, the Animal class defines a virtual MakeSound method that can be overridden by its subclasses. The Dog class overrides the MakeSound method and provides a different implementation that prints “The dog barks.” to the console.

We can create objects of both the Animal and Dog classes and call the MakeSound method on them:

Animal animal = new Animal();

Dog dog = new Dog();

animal.MakeSound(); // Output: The animal makes a sound.

dog.MakeSound(); // Output: The dog barks.

By using polymorphism in this way, we can write code that is more flexible and adaptable to different types of objects, without having to know the exact type of the object at compile time. This makes our code more modular and easier to maintain over time.

Abstraction:

Abstraction is the concept of hiding unnecessary details and complexity from the user, while still providing the necessary functionality. This can make the code easier to use and maintain, as well as improve performance.

Abstraction is a core principle of object-oriented programming (OOP) that refers to the ability to hide the implementation details of a class from the outside world and expose only the relevant features and behaviours through a simplified interface. In C#, abstraction is achieved using abstract classes and interfaces.

An abstract class is a class that cannot be instantiated directly and can only be used as a base class for other classes. It may contain abstract methods, which are declared but not implemented in the abstract class. The subclasses of an abstract class must implement all its abstract methods to be instantiated.

Here’s an example of an abstract class in C#:

public abstract class Shape

{

    public abstract float GetArea();

}

In this example, the Shape class is declared as abstract, which means that it cannot be instantiated directly. It contains an abstract GetArea method, which is declared but not implemented in the abstract class.

Subclasses of the Shape class must provide their own implementation of the GetArea method in order to be instantiated. Here’s an example of a Rectangle class that extends the Shape class and implements the GetArea method:

public class Rectangle : Shape

{

    public float Width { get; set; }

    public float Height { get; set; }

    public override float GetArea()

    {

        return Width * Height;

    }

}

In this example, the Rectangle class extends the Shape class and provides its own implementation of the GetArea method, which calculates the area of a rectangle based on its width and height.

An interface is a contract that specifies a set of methods and properties that a class must implement. It does not contain any implementation code, but rather defines a set of public members that must be implemented by any class that implements the interface.

Here’s an example of an interface in C#:

public interface IPlayable

{

    void Play();

    void Pause();

    void Stop();

}

In this example, the IPlayable interface defines three methods (Play, Pause, and Stop) that must be implemented by any class that implements the interface.

Classes that implement the IPlayable interface must provide their own implementation of these three methods. Here’s an example of a MediaPlayer class that implements the IPlayable interface:

public class MediaPlayer : IPlayable

{

    public void Play()

    {

        Console.WriteLine(“Playing…”);

    }

    public void Pause()

    {

        Console.WriteLine(“Paused.”);

    }

    public void Stop()

    {

        Console.WriteLine(“Stopped.”);

    }

}

In this example, the MediaPlayer class implements the IPlayable interface and provides its own implementation of the Play, Pause, and Stop methods. Any class that implements the IPlayable interface can be used interchangeably with the MediaPlayer class in any context that requires an IPlayable object.

By using abstraction in this way, we can create classes that are more flexible, modular, and easier to maintain over time. We can also create a hierarchy of related classes and interfaces that define a set of common behaviours and features that can be reused and extended in different contexts.

Select a project template (such as MVC, Web API, or Razor Pages) and click “Create.”
Step 2: Identity Framework Installation:

Following the creation of the ASP.NET Core web application, the Identity Framework must be installed. You can accomplish this by including the following package in your project:

Microsoft.AspNetCore.Identity.EntityFrameworkCore

You can install this package using the NuGet Package Manager or by adding the following line to your.csproj file:

<PackageReference Include=”Microsoft.AspNetCore.Identity.EntityFrameworkCore” Version=”2.2.0″ />

Step 3: Identity Framework Configuration:

The following step is to set up Identity Framework. You can accomplish this by including the following code in the Startup.cs file’s ConfigureServices method:

services.AddIdentity<IdentityUser, IdentityRole>()

    .AddEntityFrameworkStores<ApplicationDbContext>()

    .AddDefaultTokenProviders();

This code instructs Identity Framework to use the IdentityUser and IdentityRole classes as the user and role entities, respectively, as well as the ApplicationDbContext as the database context.

Step 4: Database Creation:

The database will be created next. You can do this by running the following command in the Package Manager Console:

Update-Database

This command will populate the database with the necessary tables.

Step 5: Implement of Authentication and Authorization

The final step is to put authentication and authorization in place. This is accomplished by appending the [Authorize] attribute to the controllers or actions that require authorization. Policies can also be used to implement more complex authorization requirements.

Identity Framework’s SignInManager and UserManager classes can be used to implement authentication.

In Conclusion, we have discussed how to use Identity Framework to secure your ASP.NET Core web application in this article. We went over the steps for developing an ASP.NET Core web application, installing and configuring the Identity Framework, creating the database, and implementing authentication and authorization. You can create a secure ASP.NET Core web application that protects your users’ data and privacy by following these steps.

Differences between ASP.NET Core and ASP.NET Framework

ASP.NET Core and ASP.NET Framework are both web application frameworks developed by Microsoft, but there are some significant differences between the two. Here are some of the key differences between ASP.NET Core and ASP.NET Framework:

  • Open-source and community-driven: ASP.NET Core is open-source and community-driven, with contributions from developers around the world. ASP.NET Framework is also open-source, but Microsoft is the primary contributor.
  • Cross-platform support: ASP.NET Core is designed to be cross-platform and can run on Windows, macOS, and Linux. ASP.NET Framework, on the other hand, is designed to run only on Windows.
  • Modular design: ASP.NET Core has a modular design, with a lightweight and customizable architecture that allows developers to choose only the components they need. ASP.NET Framework has a monolithic design and includes a large set of pre-built components, which can result in larger and slower applications.
  • Performance: ASP.NET Core is optimized for performance and can handle a larger number of requests per second than ASP.NET Framework. This is due to its lightweight design, which reduces overhead and allows it to run more efficiently.
  • Dependency Injection: ASP.NET Core includes built-in support for Dependency Injection, which makes it easier to manage dependencies and improve code maintainability. ASP.NET Framework does not include built-in support for Dependency Injection, although it is possible to implement it using third-party libraries.
  • Target platforms: ASP.NET Core is designed to target multiple platforms, including cloud, mobile, and desktop, while ASP.NET Framework is primarily targeted at web applications.

In summary, ASP.NET Core and ASP.NET Framework are both powerful web application frameworks, but they have some significant differences in terms of cross-platform support, open-source and community-driven development, modular design, performance, and target platforms. The choice between the two depends on the requirements of the project and the preferences of the developer.

Differences between ASP.NET Web Forms and ASP.NET MVC

ASP.NET Web Forms and ASP.NET MVC are two popular frameworks for building web applications in ASP.NET. Although both are built on the same platform and provide similar functionality, they have some key differences that set them apart. Here are some of the main differences between ASP.NET Web Forms and ASP.NET MVC:

  • Separation of Concerns: ASP.NET Web Forms allows mixing of markup (HTML) and code (C# or VB.NET) in the same file, which can make it difficult to maintain the code. ASP.NET MVC separates the markup and code into different files, which makes it easier to maintain the code.
  • Architecture: ASP.NET Web Forms uses a Page Controller architecture, where a single page contains all the code to handle the request and response. ASP.NET MVC, on the other hand, uses a Front Controller architecture, where a controller handles all the requests and responses for a group of pages.
  • Testability: ASP.NET MVC is more testable than ASP.NET Web Forms, as it separates the code and markup, making it easier to write automated tests.
  • URL Routing: ASP.NET Web Forms does not have built-in URL routing support, which can make it difficult to create search engine friendly URLs. ASP.NET MVC has built-in support for URL routing, which makes it easier to create clean and search engine friendly URLs.
  • View State: ASP.NET Web Forms uses View State to maintain the state of controls on the page. This can result in large amounts of data being sent back and forth between the server and client, which can impact the performance of the application. ASP.NET MVC does not use View State, which can improve the performance of the application.

In summary, both ASP.NET Web Forms and ASP.NET MVC are powerful frameworks for building web applications in ASP.NET. The choice between them depends on the requirements of the project and the preferences of the developer. If you need more control over the markup and want to create search engine friendly URLs, ASP.NET MVC may be the better choice. If you need a rapid application development tool and are comfortable with the Page Controller architecture, then ASP.NET Web Forms may be the better choice.

ENTITY FRAMEWORK


What is Entity Framework?
We (developers) used to frequently write ADO.NET code or Enterprise Data Access Block in Dot NET 3.5 to save or retrieve application data from the underlying database. Microsoft has provided a framework called “Entity Framework” to automate all these database-related activities for your application. Entity Framework is a Microsoft-supported open-source ORM framework for.NET applications. It enables developers to work with data using objects of domain-specific classes without focusing on the underlying database tables and columns where this data is stored.

Entity Framework in C#:
In this article, we will see how to use Entity Framework in C# applications using Visual Studio. The examples in this and likely future articles will use C# under Win Forms, but as previously stated, this choice will not affect a different intended use that the developer may reasonably request.

ORM in C#:
Optical mark recognition (also called optical mark reading or OMR) is the process of using hardware, software, or both to capture fields, for example, marks on documents such as multiple-choice questions, questionnaires with true or false fields, and other document forms.


Types of ORM Fields:

There are numerous types of OMR fields, but this section will give an overview of some of the most common ones. There can be shapes like squares, circles, and ovals.

Why Entity Framework in .NET Applications?
 Entity Framework is an ORM tool, and ORM tools are primarily used to boost developer productivity by eliminating the redundant task of performing CRUD operations against a database in a.NET application.
 Entity Framework can generate the necessary database commands for doing the database CRUD operation, i.e., can generate select, insert, update, and delete commands for us.
 While working with Entity Framework, we can perform different types of operations on the domain objects (basically classes representing database tables) using LINQ to entities.
 Entity Framework will generate and execute the SQL command in the database and then store the results in the instances of your domain objects so that you can do different types of operations on the data.

Prerequisites to Learn Entity Framework:
To fully benefit from this Entity Framework Course, you should have a basic understanding of C# as well as any database such as SQL Server, Oracle, or MySQL. It is recommended that you install the.NET Framework, Visual Studio, and SQL Server on your computer.

Advantages of Entity Framework:
Productivity:
Entity Framework can take up to 35 percent of the entire application code. It makes the developer’s life easier than ever. Despite its limitations, the designer integrated into Visual Studio dramatically simplifies the mapping process.
Maintainability:
Since you have fewer lines of code to fetch data from the database, the fewer lines of code you have to maintain.
Performance:
The complexity of ORM introduces an obvious slowdown in performance. In the entity framework first request to fetch data is a little bit slow but after that is fast to fetch data from the database.
Transactions:
ORM does all possible automation as transactions while querying the data or storing the data periodically. We can also customize transaction management practices to make the most of it out of the entity framework.

ASP.NET Core:

ASP.NET Core – Introduction

ASP.NET Core is a free and open-source platform for creating high-performance online applications. It was meant to be lightweight, modular, and highly scalable, making it a popular choice for developers looking to construct online applications rapidly and effectively. In this post, we’ll look at ASP.NET Core and why it’s such a popular choice for developing online apps.

As the successor to the ASP.NET framework, ASP.NET Core was originally published in 2016. One of the key aims of ASP.NET Core was to build a cross-platform framework that could operate on Windows, Linux, and macOS. This was accomplished by building ASP.NET Core as a modular system, with various components that could be added or deleted as needed.

One of the most important characteristics of ASP.NET Core is its ability to operate on many platforms. The usage of.NET Core, a cross-platform version of the.NET runtime, enables this. This implies that developers may create web applications with the same codebase and run them on multiple operating platforms without changing anything.

Support for current web development approaches is another aspect of ASP.NET Core. ASP.NET Core has support for major client-side frameworks including Angular, React, and Vue. This enables developers to design complex, responsive web apps that deliver an excellent user experience.

ASP.NET Core also provides outstanding speed and scalability. The framework is intended to be quick and efficient, with low memory utilisation and quick startup times. It also has caching and load balancing features, making it simple to expand web applications to meet huge traffic.

ASP.NET Core includes a large ecosystem of tools and frameworks in addition to these functionalities. This includes Microsoft Visual Studio, a popular IDE for developing web applications, as well as a variety of open-source modules for everything from authentication to database access.

Overall, ASP.NET Core provides a strong framework for developing contemporary online apps. It is a popular choice among developers because to its support for cross-platform development, current web development methods, and good performance and scalability. If you want to develop online apps fast and effectively, ASP.NET Core is a great option.

Advantages on ASP.NET Core:

ASP.NET Core is a cutting-edge, cross-platform web development framework that has several benefits over other web development frameworks. In this post, we’ll look at some of the primary benefits of developing websites using ASP.NET Core.

Open-Source and Community-Driven:

ASP.NET Core is an open-source framework with a big and active development community. This implies that there are several libraries and tools available to assist developers in creating more efficient web apps. It also implies that there is an abundance of community assistance, such as online forums, blogs, and tutorials.

Cross-Platform Support:

One of the most significant advantages of ASP.NET Core is its ability to operate on different platforms, including Windows, Linux, and macOS. The usage of.NET Core, a cross-platform version of the.NET runtime, enables this. This enables developers to create web applications with the same codebase and run them on multiple operating systems with no modifications.

High Performance:

ASP.NET Core is intended to be quick and efficient, with low memory utilisation and quick startup times. It has a lightweight and modular design, allowing for increased performance and scalability. This makes it a good choice for developing online apps that must manage large traffic and respond quickly.

Modern Web Development Practices:

Modern web development approaches, such as client-side frameworks like Angular, React, and Vue, are embedded into ASP.NET Core. This enables developers to design responsive and dynamic web apps that deliver an excellent user experience. Tag helpers, which ease the process of creating HTML forms, and middleware, which provides a flexible and composable approach to handle requests, are also included in ASP.NET Core.

Security:

ASP.NET Core has a number of security capabilities that aid in the protection of online applications against typical threats like as cross-site scripting (XSS) and cross-site request forgery (CSRF). Built-in HTTPS support and the ability to encrypt sensitive data are among these features. It also contains login and authorisation tools that make controlling access to various portions of a web application simple.

In conclusion, ASP.NET Core provides several benefits for online development, including cross-platform compatibility, high performance, current web development standards, security features, and an active and friendly community. If you want to create contemporary, high-performance online apps, ASP.NET Core is a great option.

Microsoft SharePoint:

Microsoft SharePoint:

Microsoft SharePoint is a web-based collaboration system that enables corporate teams to collaborate using workflow applications, “list” databases, other web elements, and security features. SharePoint also enables the organisation using the platform to manage information access and streamline workflows between business units.

Microsoft SharePoint is a platform for document management and collaboration that aids a business in managing archives, documents, reports, and other content that is essential to its operational procedures. Enterprise content management features of SharePoint are beneficial to businesses in all sectors and in every division within a company.

SharePoint configuration is done through a web browser. It offers most of its features through web applications and a web user interface (UI). SharePoint is used to monitor analytics, create, and remove sites, enable, and disable product features, edit content, and site layout, and create and delete sites.

SharePoint Online: There are numerous additional integration options available with other cloud services in the Microsoft Cloud version of SharePoint, called SharePoint Online. With an Office 365 or Microsoft 365 licence, it functions in combination with many of the other services Microsoft provides.
The most recent version of SharePoint is 2019. The version of SharePoint that is included with Office 365 is called SharePoint Online. For businesses who prefer to retain their data in-house for compliance or security concerns, Microsoft also provides an on-premises version.

SharePoint Server: SharePoint Server is a programme that runs on a local machine within a corporate network, such as an internal web server. It gives you more control over teams and groups, as well as additional site customization. If the intranet is hosted behind a local firewall, it may also provide additional security. Because SharePoint Server is hosted locally, it necessitates additional hardware, additional administration, and manual updates. As a result, SharePoint Server is typically used for enterprise applications that require more customization and security.

SharePoint App: Apps in Microsoft SharePoint are integrations that add features to the platform’s standard collaboration spaces. Some apps are included with the platform out of the box, but many others add features and options that are not included with the standard SharePoint platform. These can range from a library where users can store and share documents and files to calendar plug-ins and powerful workflow apps like Nintex, which make it easy to perform many repeatable logical actions in SharePoint.

Benefits of Using SharePoint:
SharePoint boosts the productivity and visibility of information workers in all industries, large and small. SharePoint’s features revolve around an intranet-based cross collaboration experience that enables secure sharing, content management, and workflow collaboration, among other things.
SharePoint is an easy-to-maintain website-based collaboration platform that business users can understand at a basic level. It is also infinitely customizable and massively scalable, so businesses can use it in a variety of ways to increase productivity and return on investment.

You can use Microsoft SharePoint on your PC, Mac, or mobile device to:

  • Create intranet sites, including pages, document libraries, and lists.

  • Add web parts to your content to make it more personalised.

  • Use a team or communication site to display important visuals, news, and updates.

  • Discover, follow, and search for sites, files, and people throughout your organisation.

  • Workflows, forms, and lists can help you manage your daily tasks.

  • Sync and save your files to the cloud so that anyone can securely collaborate with you.

  • With the mobile app, you can stay up to date on the latest news while on the go.

Partial View in MVC – ASP.NET

Partial View in MVC:

In ASP.NET MVC, a partial view is a special view that renders only a portion of the view content. It’s similar to a web form application’s user control. Partial can be reused in different views. It aids us in reducing code duplication. To put it another way, a partial view allows us to render a view within the parent view.

The partial view is implemented with its own copy of the parent view’s ViewDataDictionary object, so that the partial view can access the parent view’s data. The parent view’s data is unaffected if we change this data (ViewDataDictionary object). When related data that we want to render in a partial view is part of our model, we generally use the Partial rendering method of the view.

A partial view is a Razor markup file (.cshtml) without a @page directive that renders HTML output within the rendered output of another markup file.

When developing an MVC app, where markup files are called views, or a Razor Pages app, where markup files are called pages, the term partial view is used. This topic refers to MVC views and Razor Pages pages as markup files in general.

Difference between view and partial view in MVC: View is a complete markup that may include a master view (or master page) with all the design(s), whereas partial view is only a portion of the page or a small markup that does not include a master page. It is primarily used as a user control in mvc and can be applied to multiple views.

When to use partial views

Partial views are a useful technique when:

  • Large markup files should be divided into smaller parts. i.e. There is a benefit to working with each logical item separately in a partial view when working with a large, sophisticated markup file that is divided into numerous logical sections. Because the markup only provides references to partial views and the overall page structure, it is possible to handle the code in the markup file.
  • Reduce the amount of common markup content that is duplicated across markup files. i.e. When the same markup elements are used in multiple markup files, a partial view consolidates the markup content into a single partial view file. When the markup in the partial view is changed, the rendered output of the markup files that use the partial view is updated.

Note:

Partial views should not be used to keep common layout elements in place. _Layout.cshtml files should contain common layout elements.

When complex rendering logic or code execution is required to render the markup, do not use a partial view. Use a view component instead of a partial view in such cases.

How to Declare partial views

The names of partial views frequently begin with an underscore (_). This naming convention is optional, but it aids in visually distinguishing partial views from views and pages.

A partial view is a.cshtml markup file that is kept in the Views folder (MVC) or Pages folder(Razor Pages) but does not contain a @page directive

A controller’s ViewResult in ASP.NET Core MVC can return a full view or a partial view. A PageModel can return a partial view in Razor Pages that is represented as a PartialViewResult object. The Reference a partial view section goes over rendering and referencing partial views.

Stored Procedure – SQL

Stored Procedure:

A stored procedure is a collection of Structured Query Language (SQL) statements with a unique name that are stored as a group in a relational database management system (RDBMS) to be reused and shared by multiple programmes.

Stored procedures can access or modify data in a database, but they are not tied to a specific database or object, which provides several benefits.

So, if you have a SQL query that you write repeatedly, save it as a stored procedure and simply call it to execute it.

Additionally, you can send parameters to a stored procedure, allowing it to take action based on the value(s) of the passed parameters.

 

Advantages of Using Stored Procedures:

An essential layer of protection is added by a stored procedure between the user interface and the database. Because end users can add or modify data but not develop procedures, it enables security through data access controls. Since data is entered consistently while using a stored procedure, data integrity is maintained. Because statements in a stored method just need to be written once, productivity is increased.

Stored procedures are preferable to embedding queries in a graphical user interface (GUI). When a problem arises in an application, it is easier to troubleshoot because stored procedures are modular. Stored procedures are also tuneable, so there is no need to change the GUI source code to improve its performance. It is simpler to code stored procedures than it is to build a query using a GUI.

When using stored procedures, network traffic between clients and servers can be reduced Because commands are performed as a single batch of code. This implies that only the call to run the procedure—rather than each individual line of code—is delivered across a network.

 

Stored Procedure in SQL Server:

SQL Server stored procedures can accept input parameters and return multiple values of output parameters; stored procedures in SQL Server programme statements to perform database operations and return a status value to a calling procedure or batch.

Except when a read-only (resource database) is utilised, user-defined procedures can be created in user-defined databases or in all system databases. They are created using Microsoft’s T-SQL or Transact-SQL. There are two sorts of temporary procedures: local and global, both of which are kept in Temporary database. While global procedures are visible to any user once they are generated, local procedures are only available to the user connection that is active at the time. Physically, system procedures are kept in a hidden resource database that comes with SQL Server. They can be found in a user-defined database as well as each system’s SYS schema.

 

Stored Procedure Syntax in SQL:

Syntax To Create Stored Procedure:

CREATE PROCEDURE Procedurename
AS
SQL STATEMENT
GO;

Syntax To Execute Stored Procedure:

EXEC Procedurename;

 

Various types of stored procedures Server SQL:

 

System Defined Stored Procedure: SQL Server already has these stored procedures defined. These are physically stored in a hidden SQL Server Resource Database and logically appear in each user-defined and system-defined database’s sys schema. The sp_ prefix is used to begin this procedure. As a result, we avoid using this prefix when naming user-defined procedures.

Extended Procedure: Extended procedures interface with external programmes to perform various maintenance tasks. These extended procedures are stored in the Master database and begin with the xp_ prefix. Essentially, these are used to automatically call programmes on the server from a stored procedure or a trigger run by the server.

User-Defined Stored Procedure: The user creates these procedures for his or her own actions. Except for the Resource database, these can be created in any system database or in a user-defined database.

CLR Stored Procedure: CLR stored procedures are a type of procedure that is based on the.net framework’s CLR (Common Language Runtime). CLR procedure integration was introduced with SQL Server 2008, allowing procedures to be coded in.NET languages such as C#, Visual Basic, and F#. I’ll go over the CLR stored procedure later.

Selenium Automation Testing with C#

Automation Testing:
Due to the increasing demand for effective software products, each software development team must conduct several tests before to releasing the finished product onto the market. Before a software product is launched, test engineers work hard to find any flaws or bugs, yet deployed software is always flawed. Even with the best manual testing procedures, there is always a chance that the finished software product will have a flaw or won’t be able to satisfy the needs of the end user. The best approach to improve the efficacy, efficiency, and coverage of your software testing is through automation testing.
Automation testing employs specialised tools to automate the execution of manually designed test cases without the involvement of humans. Automation testing tools can access test data, control test execution, and compare actual results to expected results. As a result, detailed test reports of the system under test are generated.
Automation testing on an application includes both functional and performance tests.

Selenium:
Selenium is a vital automation testing tool because it supports a wide range of programming languages, including Java, Python, C#, Ruby, Perl, and PHP and to automate test scripts in a variety of browsers, including Google Chrome, Firefox, Safari, Internet Explorer, and Opera, on a variety of operating systems, including Windows, Mac, and Linux.
Selenium is a popular open-source Web UI (User Interface) automation testing suite.
Selenium can be used to automate functional tests and is compatible with automation testing tools like Maven, Jenkins, and Docker to achieve continuous testing. It can also be used in conjunction with tools like TestNG and JUnit to manage test cases and generate reports.

Selenium Tool Suite:
Selenium is a software suite, that supports automation testing in various ways and is not a single tool. It is made up of four major components, which are as follows:
• Selenium Integrated Development Environment (Selenium IDE)
• Selenium Remote Control (Selenium RC)
• WebDriver
• Selenium Grid

Selenium IDE:
Selenium IDE is a Firefox extension that allows test scripts to be recorded and played back. Testers can export recorded scripts in a variety of languages, including HTML, Java, Ruby, RSpec, Python, C#, JUnit, and TestNG. These exported scripts can be used in Selenium RC or Web driver.
The scope of the Selenium IDE is limited, and the generated test scripts are not very robust or portable.

Selenium RC:
The Selenium RC (officially deprecated by selenium) framework enables testers to create automated web application UI tests in any of the supported programming languages. It also includes an HTTP proxy server, which convinces the browser that the web application being tested is from the domain specified by the proxy server.
Selenium RC is comprised of two parts.
• RC Server for Selenium (acts as a HTTP proxy for web requests)
• Client for Selenium RC (library containing your programming language code)
Selenium RC was very effective for testing complex AJAX-based web user interfaces as part of a Continuous Integration System.

Web Driver:
The successor to Selenium RC, Selenium Web Driver (Selenium 2), is by far the most important component of the Selenium Suite. Selenium Web Driver offers a programming interface for creating and running test cases. Test scripts are written to identify web elements on web pages and then perform desired actions on those elements.
Selenium Web Driver is much faster than Selenium RC because it makes direct calls to web browsers. To interact with the web browser, RC requires the use of an RC server. Since WebDriver calls the methods of different browsers directly, we have a separate driver for each browser. Some of the most popular web drivers are:
• Mozilla Firefox Driver (Gecko Driver)
• Google Chrome Driver
• Internet Explorer Driver
• Opera Driver

Selenium Grid:
Selenium Grid is another important component of Selenium Suite that allows us to run our tests on multiple machines against multiple browsers at the same time. In other words, we can run our tests on multiple machines running different browsers and operating systems at the same time.
To achieve parallel execution of test scripts, Selenium Grid employs the Hub-Node Architecture. The Hub is the network’s master, while the nodes are its slaves. The Hub manages the execution of test scripts on various network nodes.

C# programming language:
C# is an object-oriented programming language that is pronounced C-sharp and runs on the.Net framework.
The CLR, or Common Language Runtime, is built to run the C# programming language.
C# is also known as a structured programming language since it allows us to segment programmes using functions.

The benefits of C# for automation testing are
C# is useful for automation testing because it allows the automation test engineer to create an application on the.Net framework using Visual Studio. As C# IDE is Visual Studio, it provides a faster development and debugging experience than Java’s Eclipse.
• C# is a programming language that supports Selenium binding, this language binding will also be updated in combination with the Java code.
• C# has many built-in functions that speed up development.

Our Basic Couse Module:

Software Testing

Testing:

The process of testing involves running a program to look for errors. The software must be error-free to function properly. The software will be free of all errors if testing is successful.

Guidelines for Testing:

  • The client requirements should be met by all testing.
  • software should be tested by a third party.
  • It is not possible to conduct elaborative testing. Because we need the least amount of testing possible based on the application’s risk assessment.
  • All tests should be planned before they are carried out.
  • Test small parts first, then progress to larger parts.

Types of testing:

  • Manual Testing
  • Automatic Testing

Manual Testing:

Manual testing is a method of software testing in which test cases are executed manually rather than using an automated tool. Manual testing is one of the most fundamental testing processes because it can trace both visible and hidden software defects. All test cases are manually executed by the tester from the perspective of the end user. Test case reports are manually created.

Types of Manual Testing

o          White Box Testing – Developers perform white box testing, which involves checking every line of code before passing it to the Test Engineer. Because the code is visible to the developer during testing, it is also known as white box testing.

o          Black Box Testing – The Test Engineer performs black box testing to ensure that an application or software meets the needs of the customer or client. The code is not visible while testing, which is why it is referred to as black-box testing.

o          Gray Box Testing – Gray box testing is a hybrid of white box and black box testing methods. It can be done by someone who is familiar with both coding and testing. Gray box testing is used when a single person performs both white box and black box testing for an application.

Why is Manual Testing preferred?

  • It doesn’t require any programming knowledge and easy to learn for new testers.
  • It ensures that the software is a hundred percent bug-free and a cost-effective method
  • It is used to test GUI designs that change dynamically
  • The Tester interacts with software as a real user

Drawbacks of Manual Testing:

  • It generally requires a large amount of human resources and a very time consuming method.
  • It does not test for all aspects of testing.

Automatic Testing

Automated testing is a technique in which the tester writes their own scripts and uses appropriate software or an automation tool to test the software.

It is a manual process that has been automated. It Allows repetitive tasks to be completed without the intervention of a Manual Tester.

Automation Testing Process:

Some Popular Automation Tools are Selenium, QTP, TestNG, etc

Advantages of Automation Testing:

  • Simplifies the execution of test cases
  • Increases the Reliability of Tests
  • Minimizes Human Interaction
  • It saves both time and money.
  • increases the number of tests covered

Selenium automation testing:

Selenium is a free (open source), popular automated web application testing framework. It is a browser-based automation framework that simulates and automates user actions. Selenium is a collection of tools that serve a variety of Selenium automation testing needs. Selenium automation testing is a test that is run using the Selenium framework.

Selenium Test Scripts can be written in a variety of programming languages, including Java, C#, and Python.

Selenium is simple to install on platforms such as Windows, Linux, Solaris, and Macintosh. Furthermore, it supports operating systems (OS) for mobile applications such as iOS, Windows Mobile, and Android.

Selenium supports Internet Explorer, Mozilla Firefox, Google Chrome, and Safari browsers.

Selenium can be used to automate functional tests and is compatible with automation testing tools like Maven, Jenkins, and Docker to achieve continuous testing. It can also be used in conjunction with tools like TestNG and JUnit to manage test cases and generate reports.

 

 

Negotiation in Project Management:

Negotiation in Project Management:

Negotiation is a process by which people get into an agreement by avoiding arguments. A good negotiator should always look for a Win – Win situation. Negotiation is the important management skill for any Project manager as they spent most of their time in communication with stakeholders.

  4. Revision: This can include negotiating compromises prior to formalizing an agreement.

 

Achieving a Win-Win Outcome:

Almost all negotiations yield the best results when both parties leave with a positive feeling about achieving their objectives i.e., is a win-win outcome.

This ideal situation can be accomplished by the four keys:

  1. Avoid focusing your negotiation on a single issue.

SQL Server Joins

SQL JOIN

The statement JOIN is used to combine the rows of two or more tables based  on a common column.

The different types of JOIN statement used in SQL are

  • INNER JOIN or JOIN – combines the data that matches  in both tables.
  • LEFT JOIN or LEFT OUTER JOIN – combines all the datas of left table with the datas from right table that matches.
  • RIGHT JOIN or RIGHT OUTER JOIN – combines all the datas of right table with the datas from left table that matches.
  • FULL JOIN or FULL OUTER JOIN – combines all the datas either from left or right table whenever there is a match found.

Let us consider an example:

Create a database with a name “StudentResults”

create database  StudentResults

Create a table “studentdetails” with following snippet

CREATE TABLE studentdetails (

regno int,

LastName varchar(255),

FirstName varchar(255),

age int,

dummyno int

);

Let us consider the following datas in table “studentdetails”

Create another table “result” with the snippet

CREATE TABLE result (

dummyno int,

marks int,

result varchar(10)

);

Let us consider the following datas in table “result”

 

INNER JOIN:

Inner Join is the most simplest Join. When inner join keyword is used in two tables, it will create a resulting table with combining the rows of both the tables until the condition is satisfied

For the above considered example, when inner join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM result

INNER JOIN studentdetails

ON studentdetails.dummyno=result.dummyno;

The resulting table will be

LEFT JOIN:

 Left join is also called as Left outer join. When left join keyword is used in two tables, it will create a resulting table with combining all the datas of left table with the datas from right table that matches.

For the considered example, when left join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM studentdetails

LEFT JOIN result

ON studentdetails.dummyno=result.dummyno

ORDER BY studentdetails.regno;

The resulting table will be

RIGHT JOIN:

 Right join is also called as right outer join. When right join keyword is used in two tables, it will create a resulting table with combining all the datas of right table with the datas from left table that matches.

For the considered example, when right join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM studentdetails

RIGHT JOIN result

ON studentdetails.dummyno=result.dummyno

ORDER BY studentdetails.regno;

The resulting table will be

FULL JOIN:

 Full join is also called as Outer join. When full join keyword is used in two tables, it will create a resulting table with combining all the datas either from left or right table whenever there is a match found.

For the considered example, when full join statement is used as follows

SELECT studentdetails.regno, studentdetails.FirstName, studentdetails.LastName, studentdetails.age, result.marks, result.result

FROM studentdetails

FULL OUTER JOIN result

ON studentdetails.dummyno=result.dummyno

ORDER BY studentdetails.regno;

The resulting table will be

ASP.NET Vs ASP.NET Core

ASP.NET:

ASP.NET is a basic web development tool designed and developed by Microsoft, it is used to create windows applications, websites, and web services. There are around 60 programming languages available on the ASP.NET platform, among which VB.Net and C# are mostly used.

ASP.NET Core

ASP.NET Core is a new version of ASP.NET, which was also released by Microsoft. It is a free, open source, general-purpose development tool used to develop modern cloud-based software applications on Windows or Linux or mac operating systems. It was launched as a version of ASP.NET (i. e ASP.NET 5) and later it was renamed as ASP.NET Core.

Table: difference between ASP.NET and ASP.NET Core:

ASP.NET 

ASP.NET Core

Only some components of the ASP.NET Framework are open source.

ASP.NET Core is completely a free and open-source tool.

It runs only on ASP.NET Framework.

It runs on ASP.NET Core and ASP.NET Framework.

Performance is good.

Performance is very high than ASP.NET.

ASP.NET Framework is compatible only with the Windows operating system.

ASP.NET Core is compatible with various operating systems — Windows, Linux, and Mac OS.

It Supports Web-Forms, MVC and Web API.

It supports MVC, Web API and web pages of ASP.NET Core2.0. but does not support Web-Forms.

C#, VB, and many other languages can be used.

 C# and F# languages are only supportable.

All major versions supported.

Supports Visual Studio core from version 3 to current version.

Whenever we modify or update a code, we need to re-compile the program.

Whenever we modify or update a code, the Core Browser refresh will compile and execute the program itself, So no need to re-compile it again.

It is not suitable for any mobile application development. But used for the development of both desktop and web applications.

It is not suitable for desktop application development, but suits well for development of web, windows mobile and windows store.

In case of mobile applications, it can be used on devices which work on android and windows OS, Xamarin’s tools is used to configure such mobile applications.

It is installed as a single package for Windows OS.

As it is cross-platform, it is packaged and installed individually depending on the operating system used.

ASP.NET Framework is heavy for Command Line Interface (CLI).

ASP.NET core gives a lightweight CLI.

Code access security is available for security purposes.

No such security features available.

 

Summary:
If your application

  • is to be designed to run only on Windows
  • uses only the technologies of ASP.NET framework and if it does not support the technology of ASP.NET Core
  • is already running on ASP.NET Framework

Then it is better to choose ASP.NET Framework.

 If you are

  • developing a new application and have a choice to choose between ASP.NET Core or ASP.NET Framework
  • Targeting for microservices applications
  • in need of a tool with features such as cross-platform, high performance, and scalability

Then ASP.NET Core is best choice.

 The ASP.NET Core has the following advantages in comparison to ASP.NET Framework

  • Open Source
  • Cross-Platform
  • High Performance
  • Multiple development platform
  • Multi environmental modes

 

Subquery in SQL

Query: A query is a request for data or information from one or more tables of a database.

Sub Query: In SQL language, we can place a Query inside another Query. This Query which is placed inside another query is called as subquery, also known as Nested Query

Subqueries can be used with SELECT, UPDATE, INSERT, DELETE statements along with the equality operator or comparison operator such as =, >, =, <= and Like operator.

Subquery must be enclosed in parentheses.

An ORDER BY command cannot be used in a subquery, but the main query can use an ORDER BY. The GROUP BY command can be used instead of ORDER BY in a subquery.

 

Subquery – SELECT Statement

Consider a Query

Select * from StudentDetails

When this query when executed, selects all rows of the table

Now consider an example with subquery Select

Select * from StudentDetails

where ID in (Select ID from StudentDetails where Percentage > 90);

When this set of queries gets executed,

Always the subquery gets executed first, selects the ID from StudentDetails table whose percentage is greater than 90, And then the outer query gets executed later, selecting the ID equal to the result of subquey

 

Subquery – INSERT Statement

Now consider an example with subquery Insert

Insert into StudentDetails_new

Select * from StudentDetails where ID in (Select ID from StudentDetails );

Here a new table with StudentDetails_new is created with the same structure as StudentDetails table, now to copy the datas of StudentDetails table to StudentDetails_new table , insert  statement can be used.

 

Subquery – UPDATE Statement

Now consider an example with subquery update

update StudentDetails

Set mark = mark + 5

Where mark in (Select mark from StudentDetails where mark >= 91);

Here in the table StudentDetails, the mark can be updated with a bonus of 5 marks for those who have scored mark of 91 and above using this update statement.

 

Subquery – DELETE Statement

Now consider an example with subquery delete

Delete from StudentDetails

Where mark in (Select mark from StudentDetails where mark < 50);

Here in the table StudentDetails, the datas with marks less than 50 can be removed using delete statement.

 

SQL Constraints

SQL Constraints

Constraints are the rules that can be applied on the type of data in a table. i.e, it can be used to limit the type of data that can go into a table.

Constraints can be used either when the table is created, or after the table is created.

It can be either applied to a column in a table or to the whole table.

The constraints used in SQL are:

  • NOT NULL
  • UNIQUE
  • PRIMARY KEY
  • FOREIGN KEY
  • CHECK
  • DEFAULT
  • CREATE INDEX

 

NOT NULL: if this constraint is used in any column, then it will not allow NULL values in that particular column anymore.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL

);

In this command, all the columns are specified with NULL Constraint, so all the columns will allow NULL data in it.

 

UNIQUE: if this constraint is used in any column, then it does not allow to repeat any data or value inn that particular column anymore.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL UNIQUE,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL

);

In this command, all the ID column is specified with UNIQUE Constraint, so that the ID cannot be repeated with same data.

 

PRIMARY KEY: This constraint uniquely identifies each record in a table or column and also does  not allow NULL data in  it.

Eg:

CREATE TABLE StudentDetail (

    ID int,

    Name varchar(250) ,

    Branch varchar(250),

PRIMARY KEY (ID)

);

In this command, the PRIMARY KEY Constraint is specified for ID, so that the ID cannot be repeated with same data, also ID cannot be NULL data.

 

FOREIGN KEY: The FOREIGN KEY Constraint references a row in another table, here, the table with the foreign key Constraint is called as the child table, and the table with the primary key is called the parent table.

Eg:

Parent Table::

CREATE TABLE StudentDetail (

    ID int,

    Name varchar(250) ,

    Branch varchar(250),

PRIMARY KEY (ID)

);

Child Table::

CREATE TABLE Marks (

    Mark int NOT NULL,

    Subcode int NOT NULL,

    ID int,

    PRIMARY KEY (Mark),

    FOREIGN KEY (ID) REFERENCES StudentDetail(ID)

);

Here the “Mark” of a student in the “Table Marks” refers to the “ID”  of the student in the “Table StudentDetail”.

 

CHECK: The CHECK Constraint validates condition for new value.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL,

CHECK (Branch=’CSE’)

);

In this command, the CHECK Constraints, allows only the CSE as Branch.

 

DEFAULT: This Constraint is used to set a default value for any particular column, if any value is not specified.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) DEFAULT ‘CSE’,

);

In this command, the DEFAULT Constraints, fills the Branch as CSE in default when Branch is not specified.

 

CREATE INDEX: This Constraint is used to speed-up the process, i.e it can create and retrieve any data from the database more quickly.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL

);

CREATE INDEX ix_Branch

ON StudentDetail (Branch);

Here, in the table StudentDetail, the CREATE INDEX command creates an index ix_Branch using the Branch column.

 

SQL – Programming language

Database:

A database is an organized collection of structured information stored electronically in a computer system. It is controlled by a database management system (DBMS). A database most often contains one or more tables. Each table is identified by a name, the tables contain records with data.

SQL

SQL stands for Structured Query Language.

SQL is a standard language for relational database management system. Unlike Excel, SQL can handle over one million fields of data easily. SQL queries are more flexible than MS Excel formulas.

SQL is widely used in data science and analytics. SQL can be used in all modern relational database management systems like SQL Server, Oracle, mysql, etc.

SQL allows to

  • Create new databases, tables and stored procedures.
  • Insert, update, delete or retrieve any data from databases.
  • Execute queries in a database.

SQL commands is classified as below:

  • DDL Commands
  • DML Commands
  • DQL Commands
  • TCL Commands
  • DCL Commands

DDL Commands (Data Definition language) – used to define the database schemas, i.e. to create / modify / delete database structures.

  • Create – Command is used to create database, tables, and views.
  • Drop – Used to drop databases.
  • Alter – It is used to alter the structure of the table and databases
  • Truncate – It is used to completely remove all records from a table
  • Comment – used to add comment in data dictionary
  • Rename – used to rename an existing object in database

DML Commands (Data Manipulation Language) – used to manipulate the data present in database.

  • Insert: used to insert data into a table
  • Update: it updates existing data within a table
  • Delete: it deletes all records from a table

DQL Commands (Data Query Language) – used to perform queries on data within scheme objects.

  • Select: used to retrieve the data from the database

TCL commands (Transaction Control Language) – Used to maintain consistency of the database and to manage the transactions made by the DML commands.

  • Commit: used to permanently save any transaction into the database.
  • Rollback: it restores the database to last saved state.
  • Savepoint: used to temporarily save a transaction

DCL Commands (Data Control Language) – Used to control access to data stored in a database.

  • Grant: allows to perform specified tasks by specified users.
  • Revoke: cancels the previously granted or denied permissions.

Consume Web api Http service in MVC solution

Document by Vairavan – ganesanva@hotmail.com – + 919042710472

Create a MVC solution using Code First Approach MVC Entity framework.
Add a Web Api Controller Class as below,

Look on the WebApiConfig.cs how the Routes are made.

The API URL can be routed as both API/Controller/Id and Api/Controller/Action/Id by registering the Routes in Web api config.
Add the Below code in Api Controller(Used for CRUD),

private UsersContext db = new UsersContext();
// GET api/values
public IEnumerable<StudentDetails> GetallStudents()
{
return db.StudentDbset.ToList();
}
// GET api/values/5
public StudentDetails GetStudents(int id)
{
StudentDetails studentdetails = db.StudentDbset.Find(id);
return studentdetails;
}
[HttpPost]
[ActionName(“Delete”)]
// Post api/values/Delete/5
public string DeleteStudents(int id)
{
StudentDetails studentdetails = db.StudentDbset.Find(id);
db.StudentDbset.Remove(studentdetails);
db.SaveChanges();
return “Deleted”;
}
// POST api/values
[HttpPost]
[ActionName(“Post”)]
public void Post([FromBody]string value)
{
}
// PUT api/values/5
public void Put(int id, [FromBody]string value)
{
}
// DELETE api/values/5
public void Delete(int id)
{
}


Screen clipping taken: 02-09-2016 18:44
The Above Api methods can be accessed using below URL,
http://localhost:16842/api/Values
http://localhost:16842/api/Values/5
http://localhost:16842/api/Values/Delete/5
The data can be returned as JSON,Xml or any other format depends on the attribute.

Create a new HTML page in the Solution as index.html

Put below code in Index.html,

<!DOCTYPE html>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<title>Product App</title>
</head>
<body>
<div>
<h2>All Products</h2>
<ul id=”products” />
</div>
<div>
<h2>Search by ID</h2>
<input type=”text” id=”prodId” size=”5″ />
<input type=”button” value=”Search” onclick=”find();” />
<p id=”product” />
</div>
<script src=”http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.0.3.min.js”></script>
<script>
var uri = ‘/api/values’;
$(document).ready(function () {
// Send an AJAX request
$.getJSON(uri)
.done(function (data) {
// On success, ‘data’ contains a list of products.
$.each(data, function (key, item) {
// Add a list item for the product.
$(‘<li>’, { text: formatItem(item) }).appendTo($(‘#products’));
});
});
});
function formatItem(item) {
return item.studentName + ‘: $’ + item.Age;
}
function find() {
var id = $(‘#prodId’).val();
$.getJSON(uri + ‘/’ + id)
.done(function (data) {
$(‘#product’).text(formatItem(data));
})
.fail(function (jqXHR, textStatus, err) {
$(‘#product’).text(‘Error: ‘ + err);
});
}
</script>
</body>
</html>

Now the MVC Application Works with Controller web api repository and a HTML page.
