What is MVC in ASP.NET Core? Learn & See Example

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.
