For those of you interested in doing some Indigo programming with WinFX Beta1 RC SDK (long name, I know!!), you must install these fixes: COM+ Hotfix for Indigo and MSMQ Hotfix for Indigo. I installed it yesterday just to make sure that I'm up to speed with the "Indigo kick". Andy Milligan has a great post that shows you how you can fix an existing SDK example to work with this patch. Take a look!
