Here we go !!
Jason Zander says,
Last week you saw Soma's announcement about Visual Studio "Orcas" Beta 1 shipping. I'm pleased to announce that we have made the stand alone redist of the .NET Framework 3.5 Beta 1 available on MSDN for immediate download here.
This redist is the same version that comes with the Visual Studio release, but can be separately installed from the tools with your application.
Please enjoy the release and send us your feedback! Now I'm off to Mix'07 for more announcement fun. I hope to see you there...
