Why should you care?

Choosing the right result type keeps APIs clean and browser flows correct.

See it live — copy this example

Create an MVC project (dotnet new mvc), add the code, and run dotnet run.

// FileResult — ShopNest.Mvc example
public class HomeController : Controller
{
    public IActionResult Index() => View();
}

Run Example »

Edit the code and click Run — like W3Schools Try it Yourself.

What happened?

• Study the example line by line.
• Each part connects to FileResult.
• Edit one line, save, and run dotnet run to see what changes.

Try it yourself

1. Find an action that returns this result type.
2. Call it from the browser or Postman.
3. Compare with other result types in the same controller.
4. Change text or labels in the example and run again — watch the browser update.
5. Break the code on purpose (remove a semicolon), read the error message, then fix it.

Remember

You learned what FileResult is and when to use it. Practice by changing the example yourself. Explain it in your own words before moving on.
