I just passed the 70-529 Distributed Application Development exam. Man, this was the hardest one yet.
Anyway, I am stoked, and I learned about some really amazing .NET technologies – WSE, .NET Messaging and .NET Remoting (which is NOT dead, by the way).
As an aside: if you thought I was zealous before… Now there really is no reason not to rewrite or re-engineer that humongous enterprise financial application. (I say 2-3 years and $3-4 million – make it up with the first sale or two)
