Hi Vidas,

This sounds like a known issue we've fixed in Quarterly Update 1 service pack. If you haven't installed QU1 yet, there's a workaround you may want to try:

Just delete the TFS cache on the machine where your custom app is running and try again. The cache files would be located at:

C:\Users\<USER>\AppData\Local\Microsoft\Team Foundation\2.0\Cache

Feel free to follow up with me at hakane /at/ ms dot com.
