Web Programming 101/102
If you're new to web development or just need a refresher of some of the concepts behind it, I recommend you check out Jonas Stawski's series of webcasts on web programming, which is coming up on April in the MSDN Media Center (Spanish). I have personally had the chance of seeing Jonas in action at a few of the Florida Code Camps, and he's a very good presenter. Besides, he's also having a webcast about one of my favorite topics: WCF. You can register using the following links:
