6.5 requires Team Explorer 2008?

I am trying the upgrade to 6.5 from 5.1 and noticed the tfs VCS plugin still requires Team Explorer 2008 to be installed. Is it a requiremet even if connecting to TFS 2010 exclusively?


TeamCity requires Team Explorer 2008, 2005 or 2010. So, Team Explorer 2010 should work for you.


Unfortunately it did not happen, the builds wouldn't start and the error message was clear that they were requiring TeamExplorer 2008. Only once I installed it the builds would start again.


Do you mean TFS checkout on agent?


Nope, server. I haven't captured the screenshot on the web UI but there was a red message next to the build type on the dashboard saying that the build couln't start because the TFS plugin required TeamExplorer 2008.


I have VS 2010 installed locally (in includes Team Explorer) and it works for me. What version of Team Explorer 2010 have you installed on your server machine?


I had TeamExplorer only with SP1, no Visual Studio


Could you please check if you have:

System.Core, Version=


Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a

Do you have .NET 3.5 installed?

If versions does not match, please let me know versions you have.

I didn't until I installed TeamExplorer 2008, and now that you point it out it was complaining exactly about System.Core 3.5 missing. I did not have fx 3.5 installed before. It appears it is a requirement then?


I'll fix it in 6.5.2.

Does it work if you have .NET 3.5 installed?
