So I owe everyone two days of trading history, and will post it shortly. In the mean time Scott Gu just posted here that Visual Studio 2008 Beta 2 is available. Download it here, or the smaller express edition here.
It is important that you also apply this patch after install, as it will inadvertently place a .net 3.5 dependency on .net 2.0 ajax applications. I am 10% complete on my download, and am uninstalling Beta 1 now. I will keep you posted on the upgrade process.
