Answer 1

I had this issue in Windows 10 when I needed IIS instead of IIS Express. New Web Project failed with OP's error. Fix was

Control Panel > Turn Windows Features on or off > Internet Information Services > World Wide Web Services > Application Development Features

tick ASP.NET 4.7 (in my case)
