ExtremeTech has a review of the PDC Longhorn bits. [radio.weblogs.com/0001011/]

Don Box says it nicely: "XAML is just an XML-based way to wire up CLR types - no more no less."

John Carroll says it nicely, I think: "Longhorn will be the first operating system where ALL functionality is designed to be accessed through managed code. WIN32's reign as the Windows API has ended, replaced by managed .NET APIs. ... WIN32 will still exist for backwards compatibility, of course, and native access APIs will exist for those applications which need it... However, Microsoft intends to ensure that all Longhorn functionality is accessible from a 100% managed program." He goes on to say other things that I think are interesting for the Longhorn developers of the future to know.

In general, anyone interested in XAML/Avalon/Longhorn should just subscribe to Chris’s blog: http://www.simplegeek.com/blogxbrowsing.asmx/GetRss?

I'll be hanging out in the Longhorn newsgroups, as will MVPs and the product groups. Come on, come all!

"Chris Sells expands on his first installment of this series by showing you how to integrate an SDI application into a shell while providing support for double-click document opening, a custom document icon, and adding documents to the Start->Document menu in the shell."

Not all PDC sessions have slides and/or code yet, but most do. Enjoy!

Paul’s site has all kinds of Longhorn screenshots and videos from the PDC.
