This is sweet timing, I just got my old HDD (2.5") on a USB up today and over the weekend Whidbey Beta 2 was released on MSDN to download , how sweet is that? Make sure to uninstall any previous versions you might have of VS.NET 2005, Yukon, Emulators, .NET CLR 2.0 (including CF.NET), etc. I will be checking it out over the next few days and letting you know what I find.
If you see an error removing J# .NET Redistributable Package 2.0 from Add/Remove Programs, then run the following from a cmd window:
msiexec /x {9046F10C-F5E7-4871-BED9-8288F19C70DF}
If you see an error removing .NET Framework 2.0 from Add/Remove Programs, then run the following:
msiexec /x {71F8EFBF-09AF-418D-91F1-52707CDFA274}
