Lab Web Applications "Summator"

I need help with that exercise as it does not work the way it is described in the book.

Creating the project with Visual Studio Community 2019 looks very different.

I selected Language: C#, Platform: Windows, Project: Web, and. then ASP.NET Core Web Application.

From the next window, I selected Web Application (Model-View-Controller) as it is is the only choice that mentions MVC.

After creating the project, the file index.cshtml (that we are supposed to edit) is nowhere to be found (not in the solution explorer, nor in the directory on the hard disk where all files related to that project are found).

Can anybody help?

Thanks,
