"Git repos are now fully supported on Team Foundation Service and that Microsoft has released Visual Studio Tools for Git. You can now choose which source control system you prefer, either the centralized version control provided by Team Foundation Version Control (TFVC) or the distributed version control provided by Git"
Microsoft embraces open-source Git for development tools @ infoworld
The implementation is based on original libget2 library
so Microsoft is officially using, selling, and supporting code written by Linus Torvalds himself!
Next step: embedded Linux VM in Windows :)
And why not, Android VM for Windows and Windows Phone.
For now, Windows Azure can run Linux, as well as Java.
That is Open Microsoft 2.0
