I'm buggering around with the extended help. I'm making some progress in a kinda-sorta, hack-n-slash machete code way, but I'm running into a lack of decent reference material. Most of it is geared towards WPF controls/forms, which is what the extended help format *isn't*. A lot of what is presented doesn't work in the extended help context and really relies on it being part of a WPF "project" in Visual Studio to automate references, intellisense, and so on. Even the AutoDesk blogs only have a brief reference regarding the 2009 release.
Anybody have some reference material for constructing extended help XAML material?
