If the same issue was posted here 5 months ago and did not get any answers, would it even make sense to post it again?

  • Nothing comes easy for that kind of issues, as they involve too many files and configuration settings. Start a new project and see if it works, and then migrate useful pieces from the old project to this new one. – Lex Li Nov 26 '21 at 13:33

If you're using .net core (or .net 5), in your .csproj file, make sure the Project property is <Project Sdk="Microsoft.NET.Sdk.Web"> and not <Project Sdk="Microsoft.NET.Sdk">.

You need to open Visual Studio Installer and click on modify for "Visual Studio 2019", then in the Web Development, Make sure to check "Development Time IIS Support" Like the image below:

This should fix your problem.

Recreating the project from scratch resolved the issue.

Double check your startup project - when I had this issue it turns out I'd inadvertently switched it to the test project.

Remove your project from the Solution and add again. It will solve your problem.
