According to briankel, there's a new "hot" build of VS.NET 2005 CTP available that didn't make the attendee bag drop. Any TechEd attendee can pick a copy up at the Visual Studio booths in the Pavilion area.
Now...since I'm not at TechEd, when is this going to be available on MSDN?
Update: Michael notes that the May CTP is available for download. And in a very long time I'll have it.
