TFS Cache

If you changed schemas TFS client, will face many strange errors like {Item already exists, out of memory, cannot run query}
Cause:
Visual Studio and Team Explorer provide a caching mechanism which can get out of sync.
Solution:

C:\Users\{your account}\AppData\Local\Microsoft\Team Foundation\1.0\Cache
C:\Users\{your account}\AppData\Local\Microsoft\Team Foundation\2.0\Cache
For Windows Xp, 2003 delete contents of this folder
C:\Documents and Settings\{your account}\Local Settings\Application Data\Microsoft\Team Foundation\1.0\Cache
