When I try to build my solution, I get the following error:
Visual Studio cannot start debugging because the debug target \'c:\\target\' is missing. P
Problem: The problem was I had bad nuget source configuration, so the solution could not start properly despite the fact it was build correctly because it still saw old dll references.
Solution: It was not enough to change nugget source url, I just had to remove entire nugget source and add it again with proper url. Clean solution and rebuild it.
