It will integrate with Team Foundation Server for source control, if that's what you mean? From memory, you will need to download and install the Team Foundation Server MSSCCI Provider files from Microsoft to make this work.
Does it work any better than it did for version 7 or is it still buggy?
I'm not sure, I'm afraid, as there is a different RH bug which means we haven't upgraded past RH6, so haven't really used RH7 or 8 very much. However, in my evaluation testing, the integration with TFS definitely works better than RH6 (fewer annoying popups and no need to hack the registry).
