Unable to start process dotnet.exe

Question

I am attempting to setup a new work space and transfer all of my projects from my old computer to the new one. However, I am getting this error when I try to run IIS Expres

Answer 1

In my case I have a few projects in one solution and none of them has been set up as startup project.

So, just right-click on project (not solution!) as choose Set as StartUp Project.
