When creating a custom control, you’ll want to choose as a base class whichever one of these classes has only the features that you want.  The core functionality for these three classes is:

    • Responding to user input (input events, command bindings)
    • Managing focus
    • Raising and responding to routed events
  • FrameworkElement adds
    • Alignment-related and Margin properties
    • Animation support
    • Data binding
    • Data templates
    • Styles
    • Defaults Focusable to false
  • Control adds

    • Background, Foreground
