How Do I Clear Visual Studio 2010 Web Cache?

On my Windows 7 machine, it's located in

%Temp%\VWDCache

and in

%LocalAppData%\Microsoft\WebsiteCache

From your additional information (team edition) this comes from Clear Client TFS Cache:

Clear Client TFS Cache

Visual Studio and Team Explorer provide a caching mechanism which can get out of sync. If I have multiple instances of a single TFS which can be connected to from a single Visual Studio client, that client can become confused.

To solve it..

For Windows Vista delete contents of this folder

%LocalAppData%\Microsoft\Team Foundation\1.0\Cache
