WPF NotifyIcon

Browse Source 
--------------
CHG   DataContext now also set on ContextMenu property. Revamped DataContext handling, which
      now not only checks whether DataContext is not null, but also leaves DataContext of
      controls unchanged, if the DataContext is bound.
CHG   Some documentation changes and cleanup, added class diagram.
