I've been playing with Beta 2 for a little bit and here is what I have noticed so far.  It seems to be pretty slow (although this may be because I have Nero burning stuff right now).  I tried to get the Alert system to work on it and typed datasets from 1.1 don't seem to get converted right (I noticed that in Beta 1 as well).  You keep getting an error about the namespace not being recognized when you try to compile.  So I then just made a reference to my 1.1 assembly and it was actually able to send a message but there was a problem with one of the callbacks being null (no idea why on that one) which caused the application to crash.  So far, it's been a bad time, but I'll continue to work with it.
