I recorded a few introductory ASP.NET AJAX Nuggets a couple of weeks ago and I'm pleased to see they've now gone live. Of course it's just my luck that the ASP.NET AJAX Beta was announced the day after I recorded these nuggets so things have changed a little bit. But if you want to find out what AJAX and Atlas are, what an ASP.NET AJAX application looks like or what the Update Panel can do for you, go take a look. Top tip - CTRL-SHIFT-G ups the playback speed to 1.4x which is still quite watchable.
Expect a bunch more of these to be coming out over the next few weeks (in fact if I wasn't suffering from the worst cold I've ever experienced I'd have another 6 in the bag by now...)
