Defining web user interfaces with Razor views

Let’s review how we can build the user interface of a web page in a modern ASP.NET Core MVC website.

There are multiple view engines that could be used to do this. The default view engine is called Razor, and it uses the @ symbol to indicate server-side code execution.

   @{
     ViewData["Title"] = "Home Page";
