Devleap.com, a site dedicated to Windows development for Italian developers, has added a new Longhorn section. Even though I can't read Italian, I like the idea of Longhorn articles in a language of romance. Read them with your sweetheart over a candle lit dinner. I know that's my plan. : )
Robert Wlodarczyk, a software engineer on the Avalon testing team, has posted a most excellent sample showing off the wide variety of effects you can apply to images in Avalon. Very cool.
Here. Brad Abrams, Lead PM on the .NET Framework team, is asking how you'd like to see Microsoft improve the WinFX documentation. Don't be shy; complaining now can improve your life later.
Here. Patrick Thompson, a PM on the WinFS team, talks about how types are defined in WinFS and how to extend them and create your own (although the extensibility of WinFS isn't enabled in the PDC bits).
In this chapter, Brent Rector provides his overview of WinFS, including the programming model and how to access items from the WinFS API and via SQL directly (the latter sounds a lot more fun that it is : ).
