The Web/Live team in Developer & Platform Evangelism has been working on building some new labs, demos, and videos for various web technologies such as the Ajax extensions, RSS, Virtual Earth, and Media Center.  This content is available on the Mix University site:  http://www.visitmix.com/university

 

One of the coolest things about this content is that several of the labs use the DinnerNow.net sample application.   For example, the RSS lab available here shows you how to build an RSS feed using ASP.NET.   This lab consists for five exercises:

    1. Create a simple list feed
    2. Add auto discover tags to an RSS feed
    3. Add Embedded HTML to the feed
    4. Create an RSS feed with a simple list extension
    5. Embed a web bug in an RSS feed

Here's a screenshot of the feed after you go through this lab.
