ASP.NET Core MVC Overview

ASP.NET Core MVC is a modern, cross-platform, and high-performance framework for building web applications with C# and .NET. It follows the Model-View-Controller (MVC) architectural pattern, which separates application concerns into three interconnected components.

The MVC Pattern

The MVC pattern is designed to promote the separation of concerns:

• Model: Represents the application's data and business logic. It is responsible for managing data, validating it, and responding to requests for manipulation.
• View: Responsible for presenting the data from the Model to the user. Views are typically HTML files with embedded C# code (Razor syntax) that dynamically generate content.
• Controller: Acts as an intermediary between the Model and the View. It handles incoming requests, interacts with the Model to retrieve or update data, and then selects the appropriate View to render the response.

Key Features of ASP.NET Core MVC

• Cross-Platform: Run your applications on Windows, macOS, and Linux.
• High Performance: Built on ASP.NET Core, which is known for its speed and efficiency.
• Unified MVC and Web API: A single programming model for creating web UIs and web APIs.
• Testability: The design encourages unit testing and integration testing.
• Tag Helpers: Server-side HTML generation using C# for a more productive development experience.
• Dependency Injection: Built-in support for dependency injection, making your code more modular and maintainable.
• Routing: A powerful and flexible routing system to map URLs to controller actions.
• Model Binding: Automatically maps incoming request data (form values, route data, query strings) to model properties.
• Validation: Built-in support for data validation.

How MVC Works in ASP.NET Core

When a user makes a request to an ASP.NET Core MVC application:

1. The request first hits the ASP.NET Core pipeline.
2. The routing engine determines which Controller and Action Method should handle the request based on the URL.
3. The Controller receives the request, interacts with the Model to fetch or update data if necessary.
4. The Controller selects the appropriate View.
5. The View uses Razor syntax to render dynamic HTML content, often using data passed from the Controller.
6. The generated HTML is sent back to the browser.

dotnet new mvc -o MyMvcApp
cd MyMvcApp
dotnet run

Benefits of Using MVC

The MVC pattern offers significant advantages for web development, including improved code organization, easier maintenance, enhanced testability, and better collaboration among development teams. By separating concerns, developers can focus on specific parts of the application without impacting others.
