+First you need to create a Xaml page in the folder /SamplePages/YourControl.  This will be the logical page used to by the app to navigate to the sample and contain code.
 
 If providing 'live' XAML, a .bind file is loaded and dynamically fed to the XamlReader.Load method to convert into actual controls.  This changes a few things about how samples need to be written (detailed below), but allows developers to actually change the sample and see the results live.

 ## 3. Have a *'Shallow Copy'* of your example in the sample page
 Even though the sample page content is ignored and the dynamic template injected, for the XamlReader to access some classes, a reference to the item is sometimes needed in the hosting app for it to be accessible.  (I assume it's an optimization thing.)  
 
-Therefore, for any new control/extension, you should still have a simplified snippet of it contained in the sample page compiled/loaded by the app.  You should remove names, events, and properties (unless extensions) from these so the namespace isn't accidently polluted.  If you re-use the same control, you don't have to include it twice.
