Answer 1

try clearing your cache folder?

C:\Users\XXXX\AppData\Local\Microsoft\Team Foundation

TFS3 is VS2010, TFS4 is VS2012, TFS5 is VS2013

Stop all instances of Visual Studio.

Zip/Rar all the files as a backup, then delete all files except for the backup zip/rar.

Restart Visual Studio and it will recreate all the files and you should be able to connect as shown here:

Answer 2

I followed this steps to get rid of this issue:

1. Close all instances of Visual Studio.
2. Open the Task Manager and check if any TFS Services are running. Select each of them and click on End Process Tree.

3. Browse to the folder below and delete all the contents and folders in

   %LocalAppData%\Microsoft\Team Foundation\4.0\Cache 
   

   and in

   %LocalAppData%\Microsoft\Team Foundation\5.0\Cache
   

4. Restart Visual Studio and try triggering build.

5. If you are switching from one version of TFS to another, you may require repeating this solution again. If you are using older version of TFS, you may have to navigate to

%LocalAppData%\Microsoft\Team Foundation\ and find out the version folder instead of navigating directly. It would be TFS3 if using VS2010, TFS4 if using VS2012, TFS5 if using VS2013.
