Introduction

In this lesson, you will learn controllers and views in ASP.NET for beginners. These are the core parts of MVC that handle user requests and display data.

What is a Controller?

A controller handles user requests and returns responses.

public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}

What is a View?

A view is used to display data to the user using HTML.

<h1>Welcome to ASP.NET</h1>

Passing Data from Controller to View

public IActionResult Index()
{
    ViewBag.Message = "Hello User";
    return View();
}

<h2>@ViewBag.Message</h2>

How They Work Together

1. User sends request
2. Controller processes request
3. Data is sent to View
4. View displays output
