At work we use P4 which is very SVN like. I do find the visual studio integration for Git (at least the official one that runs off the TF browser) to be a bit bare bones but it seems good enough. I ended up creating the repository using BitBucket’s desktop UI (SourceTree) which is very snazzy. The VS plugin is good enough for visual cues adding/modifying files and then pushing/pulling.
Well anyways, enjoy. Be sure to report any bugs on the issue tracker (I know there must be a lot lurking in the math library). If something looks incomplete though, it probably is. Not quite yet at the point where everything will work out of the box like XNA with minimal effort.
