True - but remember, there's a bunch of teams building stuff. Most of Open Tech's and Azure's open code bases are on GitHub. TypeScript isn't the biggest MS project on GitHub and I just want to make sure that nobody is using this as a "CodePlex is dead!" data point.

Not to mention ASP.NET vNext and related projects:

https://github.com/aspnet/

And WinJS https://github.com/winjs/winjs

And the Reactive Extensions for all languages: https://github.com/Reactive-Extensions/

The Microsoft repo is pretty new. Expect more to show up here soon.
