Today, I’ve passed the exam 70-561, ADO.NET Application Development, which completes my second MCTS certification. I must confess that this one was the most difficult so far, and took the most time to fulfill. I expected simple questions, but found monstrous ones, and found myself trying to figure out a single question for minutes.
However, I’ve only studied for a week (and have two years of experience building data-driven apps), so I might have been lucky to pass. As you could read it in the syllabus, the exam focused mostly on data modifying and querying, with a large percentage of synchronization-related questions. The Training Kit was useful for preparing, but you definitely need to dig through some MSDN articles, because there are serious white spots in the book.
All in all, the exam was though, and you should prepare for it more than a week, it won’t hurt your performance on it!
The next goal is the WCF exam, 70-503. I’ll start publishing posts as I review the topics, but first I’ll need to complete my university exams (you know, sociology), so there will be a slight delay, but I’ll take that one before the second shot offer expires (30th June).
And finally, some bad news: there won’t be any posts published about the Entity Framework. It’s a very useful feature, but I’m tired of trying to understand it wholly, sorry.
