This is a real newbie question:
If I create a simple project in .NET, lets say at c:\project\test,
and then change the directory name from project to say project2, when I try to open the .sln file my project will not open, I mean the .NET program opens and runs but nothing is there. If I change the directory name back to project, it still will not open the project. What is going on here?
Jorgen was right. It was a dumb question. Nothing disappeared. The answer is to find the moved project in the Solution Explorer and reload the project. Then everything works just fine.
