1) First and foremost where is the source code for the main page of the Silverlight Demos?
All I have on my drive is VB code. When I open the Examples_SL in my examples folder created in the installation there is no .CS or C# code, just VB.
On the Demo there is the control on the left. It looks like a Treeview, is it? Is there any examples of that usage? Is the entire app navigation app?
