As promised, you can get my decks and demos from www.publicsectordeveloper.com (direct link). The demos are "as-is" but feel free to let me know if something doesn't work anymore.
A more detailed explanation of the WPF deck and demos can be found here. If you are interested in WPF, then don't forget to check out the WPF Wiki.
UPDATE: I received an email from a few folks who were having trouble figuring out what to download for my Introduction to ASP.NET AJAX presentation. The direct link to the deck is here. The code is here.
