ASP.NET MVC (Model-View-Controller) is a web application framework developed by Microsoft. It is a part of the larger ASP.NET platform used for building dynamic and scalable web applications. MVC is based on the Model-View-Controller architectural pattern, which separates an application into three main components:
- Model: The model represents the data and business logic of the application. It handles data manipulation, validation, and storage. In an ASP.NET MVC application, models are typically represented by classes and can be used to interact with databases, files, or other data sources.
- View: The view is responsible for rendering the user interface. It presents the data to the user in a structured and visually appealing manner. In ASP.NET MVC, views are created using HTML, CSS, and other front-end technologies. Views are designed to be independent of the underlying data and application logic.
- Controller: The controller acts as an intermediary between the model and the view. It handles user input and processes requests from the client-side. Based on the user’s actions, the controller manipulates the model and determines which view to render. In ASP.NET MVC, controllers are responsible for receiving HTTP requests, processing the data, and returning an appropriate response, often in the form of a view.
Key features and benefits of using ASP.NET MVC include:
- Separation of Concerns: The MVC pattern promotes a clear separation between data, presentation, and application logic, making the code more maintainable and easier to test.
- Testability: The separation of concerns allows for unit testing of individual components, facilitating more robust and reliable code.
- Extensibility: ASP.NET MVC allows developers to extend and customize the framework to meet specific project requirements.
- Routing: ASP.NET MVC provides a flexible and powerful routing engine that allows developers to define custom URL patterns for their web application.
- Built-in support for Dependency Injection: Dependency Injection is an integral part of ASP.NET Core MVC, allowing for better code organization and testability.
- Razor View Engine: ASP.NET MVC uses the Razor view engine, which provides a concise and expressive syntax for creating views.
- Integrated with ASP.NET ecosystem: ASP.NET MVC integrates well with other components of the ASP.NET ecosystem, such as Web API and Entity Framework, allowing for seamless development of full-fledged web applications.
