Yep, I passed 70-320 (Xml Webservices and Server Components with Visual C#) today. The exam wasn't too hard, but could have been simpler if I had studied for the right exam! After registering for the exam with Sylvan Prometric, I was under the impression that it was 70-310 (the VB.NET version of the same exam) and I never bothered to check twice.
So you can imagine my surprise when the pre-test questions asked me if Visual C# was my primary development language. Anyway, it's a good thing that the exam mostly covers the .NET framework, and no so much the syntax of C#. Besides, I do most of my home development in C#, so any damage was limited.
Anyway, I'm an MCAD now, but I'm going for MCSD .NET. Only need to pass 70-300 which every MCSD on the older platforms received a free voucher for.
