Error when trying to access Source Control with Team Explorer

The problem is as described in the title. This was in my case due to corrupted Visual Studio version control cached data.

I fixed it like this:

Run this in Visual Studio Comman Prompt:

devenv.exe /resetuserdata

Then navigate to your TFS data on HD, it should be around here:

c:\users\developer\appdata\local\microsoft\team foundation

There delete without mercy under the cache subfolder everything. Just be sure to backup the folder data before you do this, just in case.


Visual Studio 2010 Team Foundation Server problems after TFS upgrade

After a organization I know updated successfully their TFS 2010 to TFS 2012 all was OK except that when you tired to access a project from TFS nothing would appear and no apparent error. After looking at the Visual Studio output window I noticed that a file caused problem. For some reason the following VersionControl.config file was empty and Visual Studio could not write to this file. Well I chose a direct approach and deleted the file and rebooted Visual Studio.  Surprise surprise all is OK :). So if you encounter similar problem go to the following directory and delete your VersionControl.config file(notice mine was empty which indicated that something was wrong with the file): C:\Users\”your windows user name”\AppData\Local\Microsoft\Team Foundation\3.0\Cache
