MVC (Model-View-Controller) is a design pattern in ASP.NET Core used to build scalable and maintainable web applications. It separates an application into three main components:
- Model: Represents application data and business logic.
- View: Handles UI and presentation.
- Controller: Processes requests, interacts with models, and selects views.
Key Features:
- Clear separation of concerns for easier maintenance
- Supports routing, validation, and dependency injection
- Integrates with Entity Framework for database operations
- Enables testable and modular application design
Example:
Controller action example to return a view:
public class HomeController : Controller
{
public IActionResult Index()
{
ViewData["Message"] = "Hello MVC World!";
return View();
}
}
Corresponding View (Index.cshtml):
<h1>@ViewData["Message"]</h1>
MVC in ASP.NET Core is widely used for enterprise-grade web applications due to its structure, testability, and flexibility.
