How to set up debugging in visual studio 2019? Community?

Question

C++ / C#

I created a controller in which I made the List function, using the html page template I wanted to display it on my host in order to check the ability to work, but when I start debugging it says "InvalidOperationException: The view" List" was not found The following locations were searched: / View/my method/List.cshtml I tried to specify the full path to the method in the search bar, I wrote in the services "serveces. UseMvc(option => option. Enable...), tried on 2.1,2.2,3.1 versions. Net Core, nothing helps
