Folks, not much of this is new. Both Entity Framework and ASP.NET MVC were already open source for quite some time [0][1]. All the other repos are nearly empty.
The only real news here is that, indeed, ASP.NET vNext is going to be developed in the open, or at least to some extent. But right now, not a lot of code seems to be released that wasn't already out there (although I did not go through all the repos).
I don't think you should expect to find many current/legacy parts of ASP.NET that aren't open yet: this seems to be mostly for new stuff.
Finally, don't forget that "ASP.NET" doesn't seem to mean a lot (anymore): it's basically Microsoft actively shipping the org chart. Anything that's web related and from MS appears to get tacked "ASP.NET" on front of it. Cause really, what does ASP.NET MVC, basically a pretty uninspired Rails port to C# (and just an open source library like any other), have to do with "active server pages"?
