Project could not be opened because Microsoft Visual C# 2008 compiler could not be created

 If you get an error message as appears in the post's title, you will probably get a recommendation "try to instal Visual Studio". So don't.


I found several techniques that may help solve this problem. Before you try anything (especially messing the registry), try the following command line:


devenv /ResetSkipPkgs


At least for now my problem is solved.
