My buddy ET has been working with us on TFS for as long as I can remember...in fact I think he was able to install early builds of TFS before most of the rest of the team could figure it out.  So it struck me as a bit funny to hear that he hadn't used the MSSCCI provider that Brian talks about all the time until just recently.  So, if you're a big fan of TFS but are working on older projects, such as one based in VB6, please take a look...you'll be glad you did.
