ActiveItem — A property that indicates what item the conductor is currently tracking as active. The Conductor treats deactivation and closing synonymously.
The first thing to notice is that we are using a more Xaml-developer-friendly mechanism for declaring our ActionMessages. On the non-XF platforms this method has re-entry protection, the XF version did not.
Hopefully you can see some of the differences from a Conductor without a collection and understand why those differences are there.
