I'm going to dip my foot into WCF. That's more than a toe but less than a headlong dive. Of the four books listed in our library, I have found two. Here are some quotes from the intros:
...you might instinctively treat WCF as just another API. Resist this temptation... WCF is not just a wrapper around existing functionality or just another whiz-bang API. WCF is the evidence that a tectonic shift has occurred in distributed software development.
Justin Smith, Inside Windows Communication Foundation
Tectonic shift!? Wow! Equally as eye-opening is this one:
To me, WCF is simply the next development platform, which to a large extent subsumes raw .NET programming.
Juval Lowy, Programming WCF Services
This could be fun...
