I am bit late to the party, however, if you don’t know yet, WinFX December CTP has been released for download (there is a separate downloads for SDK as usual). And the most interesting download available is Microsoft Visual Studio Code Name “Orcas” Community Technology Preview – WinFX™ Development Tools. Hint: note the keyword Orcas. AFAIK this is the first public appearance of Orcas. I can’t wait to install it. Ah, almost forgot that there is also a Pre-released WinFX Runtime Components Uninstall Tool. It didn’t work for me though (I got an exception) – I had to manually uninstall all previously WinFX installed parts.
