TF31002, VS2008 and TFS2010

It’s funny (but not at the time) how easily you can find the answer to a question once you’ve already answered the question.

Last Friday I spent way too much time trying to figure out why I was getting the error TF31002 when trying to connect my Visual Studio 2008 instance to Team Foundation Server 2010. I knew you could do it. I have the configuration running at home. I have multiple co-workers with successful configurations. Yet, on these two machine, nothing but TF31002.

Today I can search and find all kind of solutions as long as I don’t include TF31002 in my search. Searching with the terms ‘VS2008 TFS2010’, returns the solution as the first hit. Search on TF31002 gets nothing useful. That’s why I put TF31002 in the title of this post.

The setup:

VS2008 with SP1 already installed.

We installed TFS2010.

We then installed Team Explorer for VS2008 and the Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 (Installer). I tried to get to the TFS2010 box and received the error TF31002. Oh. I was told that you’re supposed to include the url to the team project :

http://server:8080/tfs/collection

That got me an nice message about not allowing ‘http:’, ‘https:’ nor ‘/’ in the server name.

Sound familiar?

Sadly, the answer is in the sequence of the installs. Since I installed Team Explorer after installing VS2008 SP1, I had to reinstall SP1 and then the Forward Compatibility Update.
