The Team Foundation Server MSSCCI Provider (TFS MSSCCI) available now!. You can download it here (If you tried to get this on 4/7/2006 and it errored out, please try again). TFS MSSCCI allows applications and development environments that serve as MSSCCI hosts to access Team Foundation Server Source Control.
Other environments that support MSSCCI should work as well, but were not tested.
The TFS MSSCCI provider is unsupported and provided "as is". However, you can ask questions on our forum or by mail and we will do our best to help. We welcome and look forward to your feedback.
Special thanks to Ben Ryan, Michal Malecki, Pei Gu, Ted Chambers and Mario Rodriguez for making this release possible.
