Is There A Current 2.0 Web Services Exam

[Mark Bondurant]

I'm studying for the 70-503 exam, which uses the new WCF architecture.
This is fine, but I also need to know about how things were done prior to
this. Can anyone recommend an exam that isn't going obsolete next March?

By the way, the book for this exam - Microsoft .NET Framework 3.5-Windows
Communication Foundation - really stinks. I guess this pretty much goes
for all MS Press books though. I wish a WRITER would write a book for
it. Something that doesn't wallow in minutia and detail, with
explanations of prickly subjects like "why", "how", and the "big
picture". Grump.
