The nice thing about .Net 3.0 is that it will work on XP, SP2 and Windows Server 2003. I've played a bit with WPF and less with WCF.

>Installing it this week, have been putting it off for a bit, well until Sql Server SP2. I can't procrastinate any more on it, lol. 3 develoment machines to upgrade to Vista, fun fun fun. Thanks for the heads up, I have downloaded the march ctp already, hopefully i can have a total nerd weekend playing with it.
