In this section you're going to modify the `HelloWorldController` class to use Razor view template files to cleanly encapsulate the process of generating HTML responses to a client.
|

|
You'll create a view template file using Razor. Razor-based view templates have a *.cshtml* file extension. They provide an elegant way to create HTML output using C#.

Currently the `Index` method returns a string with a message that is hard-coded in the controller class. In the `HelloWorldController` class, replace the `Index` method with the following code:

The `Index` method above returns a View object. It uses a view template to generate an HTML response to the browser. Controller methods (also known as action methods) such as the `Index` method above, generally return an `IActionResult` (or a class derived from `ActionResult`), not primitive types like string.
