Thanks to Brad Adams for?posting the Longhorn Architecture Diagram and the WinFX Namespace Poster (PDF / JPG). Ofcourse, the details are as we know now (ie: post PDC 2003)?and are subject to change in the coming months/years. But its all a good preview of what’s under the hood.
Apparently, there’s a Longhorn Tweak Guide already out there. And a book titled Introducing Longhorn for Developers is in works. Sam Gentile introduces?on Writing Your First Longhorn Application.
