Desert Code Camp slides and source: ASP.NET AJAX (Atlas)
Last weekend I gave a presentation at Desert Code Camp on ASP.NET AJAX. I spent a lot of time on the server extensions (UpdatePanel, ScriptManager, etc.) and tried to cover as much as I could on the client-side stuff (Networking stack, JavaScript extensions, control toolkit ...). I also tried to cover some AJAX principles, guidelines an security. Unfortunately, you can only squeeze so much into an a little over an hour. Still, the basics got covered and overall it went pretty well. Below are links to the slides and source from the presentation. Included in the source is a sample rss reader which I didn't have a chance to demonstrate.
