My BizTalk 2002 project is finally winding down and needless to stay I'm excited.  It was a very successful project but at the same time it was very frustrating to be tied down to old technology.  Our team spent weeks upon weeks developing solutions that newer versions of BTS already fixed out of the box, it was a good exercise in self control.  Its a great time to get back into BizTalk 2004-06 and WF.  I just saw that the WinFX January CTP was released.  Get it here.  There seems to be significant changes from Beta 1 to 2 so grab up those bits and play around. 

On another note, just some new BizTalk 2006 webcasts to wet your whistle.
