ASP.NET MVC filters

ASP.NET MVC filters are powerful tools that enable developers to include cross-cutting concerns in their applications. These concerns include logging, authentication, authorization, error handling, and others. Filters offer a simple and modular approach to adding functionality that can be applied globally, to specific controllers, or even to individual actions. In this article, we will look at the various types of filters available in ASP.NET MVC, as well as their use cases and how to effectively implement them.

Types of Filters in ASP.NET MVC:

ASP.NET MVC supports a variety of filters, each with a specific purpose, the types of filters in ASP.NET MVC are.

Authorization Filters

Action Filters

Result Filters

Exception Filters

Authorization Filters:

Purpose: Manage authorization logic, ensuring that users have permission to access certain resources.
Common Usage: Determine whether a user is authenticated or if they have specific roles or permissions.

Eg:

public class CustomAuthorizationFilter : AuthorizeAttribute

{

    protected override bool AuthorizeCore(HttpContextBase httpContext)

    {

        // Custom authorization logic

        return httpContext.User.Identity.IsAuthenticated;

    }

}

Action Filters:

Purpose: Run code before and after an action method is executed.
Common Usage: Logging, performance measurement, and input validation.

Eg:

public class LogActionFilter : ActionFilterAttribute

{

    public override void OnActionExecuting(ActionExecutingContext filterContext)

    {

        // Code to execute before the action runs

        Log("Action Method Executing");

    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)

    {

        // Code to execute after the action runs

        Log("Action Method Executed");

    }

    private void Log(string message)

    {

        // Logging logic

        Debug.WriteLine(message);

    }

}

Result Filters:

Purpose: Run code before and after the action result is executed.
Common usage: Modifying the result and logging.

Eg:

public class CustomResultFilter : ResultFilterAttribute

{

    public override void OnResultExecuting(ResultExecutingContext filterContext)

    {

        // Code to execute before the result runs

        Log("Result Executing");

    }

    public override void OnResultExecuted(ResultExecutedContext filterContext)

    {

        // Code to execute after the result runs

        Log("Result Executed");

    }

    private void Log(string message)

    {

        // Logging logic

        Debug.WriteLine(message);

    }

}

Exception Filters:

Purpose: Handle exceptions raised by action methods.
Common usage: Logging exceptions and returning custom error views or messages.

Eg:

public class CustomExceptionFilter : FilterAttribute, IExceptionFilter

{

    public void OnException(ExceptionContext filterContext)

    {

        // Handle the exception

        LogException(filterContext.Exception);

        // Optionally set the result to a custom error view

        filterContext.Result = new ViewResult

        {

            ViewName = "Error"

        };

        filterContext.ExceptionHandled = true;

    }

    private void LogException(Exception exception)

    {

        // Logging logic

        Debug.WriteLine(exception.Message);

    }

}

Applying Filters:

Filters can be applied in various ways:

Globally: Applied to all controllers and actions in the application.

public class FilterConfig

{

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)

    {

        filters.Add(new HandleErrorAttribute());

        filters.Add(new CustomAuthorizationFilter());

    }

}

Controller-Level: Applied to all actions within a specific controller.

[CustomAuthorizationFilter]

public class HomeController : Controller

{

    public ActionResult Index()

    {

        return View();

    }

}

Action-Level: Applied to a specific action method.

public class HomeController : Controller

{

    [LogActionFilter]

    public ActionResult Index()

    {

        return View();

    }

}

Custom Filters

Custom filters allow you to encapsulate specific behaviors that can be used throughout your application. To create a custom filter, either implement the filter interface or inherit from the base class.

Conclusion:

ASP.NET MVC filters are critical for handling cross-cutting concerns in a clean and maintainable manner. Understanding and utilizing the various types of filters can help you improve the functionality, security, and reliability of your applications. Filters, whether used globally, at the controller level, or on specific actions, provide a versatile way to intercept and process requests and responses, making them an essential tool in any ASP.NET MVC developer’s toolkit.

Understanding Encapsulation and Abstraction in C#

Two fundamental ideas in the field of object-oriented programming (OOP)—abstraction and encapsulation—are essential to creating reliable and maintainable software systems. Though they are not unique to C#, these ideas are central to the language’s architecture and are widely used in its framework and libraries. Let’s explore the meaning of abstraction and encapsulation in C# and how they help write cleaner code.

Encapsulation

A key component of object-oriented programming (OOP) in C# is encapsulation, which is the grouping of data and methods (or behaviours) that manipulate the data into a single unit called a class. Encapsulation provides controlled access to an object’s internal state through well-defined interfaces, like properties and methods, while shielding it from external manipulation and access.

Access Modifiers

Access modifiers in C# are used to manage a program’s types and members’ visibility and accessibility. By limiting the amount of access that other program components have to the encapsulated data and methods, these modifiers are essential to the encapsulation process.

• public: Any other code within the same assembly or another assembly that references it can access the member.
• private: Only members of the same class or struct may access this member.
• Protected: The member can be accessed by derived classes and by other members of the same class or struct.
• Internal: Only those in the same assembly can access the member.
• safe internal: The member can be accessed through derived classes or within the same assembly.

Properties

In C#, properties provide regulated access to a class’s private fields by encapsulating them. They guarantee data integrity by enabling data validation and manipulation prior to access or modification.

public class Person

{

    private string name;

    public string Name

    {

        get { return name; }

        set

        {

            if (!string.IsNullOrEmpty(value))

            {

                name = value;

            }

            else

            {

                throw new ArgumentException("Name cannot be empty");

            }

        }

    }

}

Methods

Methods contain an object’s behaviour. They have the ability to act or perform operations on the internal state of the object and return results.

public class Calculator

{

    public int Add(int a, int b)

    {

        return a + b;

    }

}

Advantages of Encapsulation

• Data Hiding: Encapsulation ensures data integrity by preventing unauthorized manipulation and concealing an object’s internal state from external access.
• Abstraction: By encapsulating an object, developers can concentrate on its behaviour’s key components rather than worrying about the intricacies of its internal implementation.
• Modularity: By combining related data and methods into a single unit, encapsulation encourages modularity and makes the codebase simpler to comprehend and manage.
• Code Reusability: Encapsulation makes code reuse easier by offering clearly defined interfaces that let objects be used in various contexts without needing to be modified.

To summarize, encapsulation in C# is a powerful mechanism for developing robust and maintainable software systems by hiding objects’ internal complexity and providing controlled access to their state and behaviour via well-defined interfaces. It encourages code organization, reuse, and dependability, making it a critical concept in modern software development.

Abstraction

A key component of object-oriented programming (OOP) in C# is abstraction, which is displaying only an object’s essential features while concealing the intricate implementation details of a system. It enables developers to concentrate on an object’s functionality rather than its implementation. Creating a blueprint for objects with shared traits and behaviours can be accomplished through abstraction, all without having to define each object’s precise implementation.

Abstract Classes and Methods

Abstract classes and methods are commonly utilized in C# to accomplish abstraction. A class that lacks the ability to be instantiated directly and that might include one or more abstract methods that are declared but not implemented is known as an abstract class. Specific functionality is meant to be implemented by derived classes through the use of abstract methods.

public abstract class Shape

{

    public abstract void Draw(); // Abstract method

}

public class Circle : Shape

{

    public override void Draw()

    {

        // Implementation for drawing a circle

    }

}

public class Rectangle : Shape

{

    public override void Draw()

    {

        // Implementation for drawing a rectangle

    }

}

Interfaces

Interfaces are another tool in C#’s toolkit for achieving abstraction. A contract that classes can implement is defined by an interface. It has no implementation details and only method signatures, properties, events, or indexers. All of the members defined in an interface must have implementations available in any class that implements that interface.

public interface IShape

{

    void Draw(); // Method signature

}

public class Circle : IShape

{

    public void Draw()

    {

        // Implementation for drawing a circle

    }

}

public class Rectangle : IShape

{

    public void Draw()

    {

        // Implementation for drawing a rectangle

    }

}

Benefits of Abstraction

• Flexibility: By defining common interfaces and behaviors that multiple classes can implement, abstraction makes it possible to write extensible and flexible code.
• Code Reusability: Developers can promote code reusability by defining abstract classes or interfaces, which allow code to be reused across various application components.
• Maintenance: By enabling modifications to be made to the underlying implementation without impacting the external interface accessible to other areas of the codebase, abstraction makes maintenance easier.
• Encapsulation: Since encapsulation exposes only the functionalities that are absolutely necessary while hiding the internal workings of an object, abstraction and encapsulation frequently go hand in hand.

In conclusion, abstraction in C# offers a strong tool for encouraging code reuse, controlling complexity, and creating modular, maintainable software systems. By delegating the specific implementation details to the individual classes that inherit from abstract classes or implement interfaces, it allows developers to concentrate on creating concise and clear interfaces.

Benefits of Abstraction and Encapsulation

• Modularity: Objects can be treated as black boxes, allowing changes to be made to one part of the system without affecting others.
• Code Reusability: Abstraction enables the creation of generic components that can be reused across different parts of the application.
• Security: Encapsulation prevents unauthorized access to sensitive data and provides a controlled interface for interacting with it.
• Maintainability: By hiding implementation details, abstraction and encapsulation make code easier to understand, debug, and maintain.

In conclusion, abstraction and encapsulation are essential principles in C# programming that promote code organization, flexibility, and reliability. By properly abstracting functionality and encapsulating data, developers can create robust and scalable software systems that are easier to understand, maintain, and extend.

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.

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.

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:

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

Insert some records as well using the syntax shown below.

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

Create a view using the syntax shown below.

Using a View:

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

With reference to the given example,

Updating a View:

You can use the ALTER VIEW statement to update views:

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:

Dropping a View:                

The DROP VIEW statement is used to remove a view:

Thinking back to the earlier illustration:

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.

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

Check it out with the following select query:

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

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:

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.

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:

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.

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.

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 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 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:

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”.

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.

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

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.

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

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.

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.

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.

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.

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.

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.

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

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.

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:

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:

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:

Then create a table in the corresponding database.

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

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.

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

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.

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

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.

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

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

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.

It is a comprehensive framework for developing large enterprise-scale and scalable software applications.

Dot Net is a modern, flexible, fast, and secure technology that integrates well with other technologies.
