What about MVC in .NET Core?

MVC in .NET Core

Model-View-Controller (MVC) in .NET Core is a design pattern and framework used for building web applications. It separates an application into three main components: Model, View, and Controller, which helps in achieving a clean separation of concerns. Here’s a detailed explanation of each component and how they interact within the .NET Core framework:

1. Model

  • Responsibilities: The Model represents the state of the application and any business logic or operations that should be performed. It encapsulates the data and the logic to manipulate that data. Models are responsible for data access and business rules.
  • Independence: The Model is independent of the View and Controller, which allows it to be built and tested separately from the user interface[1][3].

2. View

  • Responsibilities: The View is responsible for presenting the content through the user interface. It uses the Razor view engine to embed .NET code in HTML markup. Views should contain minimal logic, focusing mainly on displaying data provided by the Model.
  • Presentation Logic: If complex logic is needed to display data, it is recommended to use View Components, ViewModels, or view templates to simplify the View[1][3].

3. Controller

  • Responsibilities: The Controller handles user interaction, works with the Model, and selects the View to render. It acts as the intermediary between the Model and the View, processing incoming requests, performing operations on the Model, and returning the appropriate View.
  • Entry Point: The Controller is the initial entry point for user requests and is responsible for determining which Model types to work with and which View to render[1][3].

Key Features of MVC in .NET Core

  1. Separation of Concerns: MVC promotes a clear separation of concerns, making it easier to manage and scale applications. Each component (Model, View, Controller) has a distinct responsibility, which simplifies development, testing, and maintenance[1][3][8].

  2. Routing: ASP.NET Core MVC uses a powerful URL-mapping component that allows for defining comprehensible and searchable URLs. It supports both convention-based and attribute-based routing, enabling flexible URL patterns[1][3][8].

  3. Dependency Injection: ASP.NET Core MVC has built-in support for dependency injection, which helps in managing dependencies and promoting loose coupling. This makes the application more modular and easier to test[4][9][20].

  4. Testability: The framework is designed with testability in mind, supporting test-driven development (TDD). The separation of concerns and dependency injection make it easier to write unit tests for each component[1][3][8].

  5. Cross-Platform: ASP.NET Core MVC is cross-platform, allowing applications to run on Windows, macOS, and Linux. This provides flexibility in deployment and development environments[6][9][14].

  6. Performance: ASP.NET Core MVC is optimized for performance, often outperforming other popular frameworks. It is lightweight and designed to handle high traffic efficiently[6][9][14].

Example of MVC in .NET Core

Here is a simple example of how an MVC application is structured in .NET Core:

csharp Copy
// Model
public class Student
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string...
