I just upgraded my development machine from Windows XP to Windows 7 Pro 64. On both OS's, I was using VS 2008 SP1.
For some reason, VS randomly complains about one of the dlls that gets built being in use by another process and that process is always VS (devenv.exe).
It's something like this, but I've tried lots of different fixes and nothing seems to work.
Sometimes I only get one build, sometimes I get 10 or 20. I have to restart VS to fix the problem.
This solution built fine when I was running XP. I don't really understand what could have changed. Has anyone had this happen?
