All of the sudden, I'm no longer able to build a Solution without getting an error in VS 2010. A minute ago I was able to build, and now I can't.
The error is:
Unable to load referenced library 'C:\Program Files\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.DirectoryServices.dll': System Error &H8013110e&
I've checked and the .dll is there. I've re-booted and grabbed the latest version from Team Foundation Server.
Any ideas?
