Assembly: PresentationCore (in presentationcore.dll)
Although this interface is public, it is not intended to be implemented in application or framework-building scenarios. This interface is public because of the inheritance requirements for connecting the WPF core to the WPF framework. You can also use this interface as a casting mechanism to enforce that the input events and properties will come from either a FrameworkElement or FrameworkContentElement, which can be handled in the same input model. For more information, see WPF Architecture and also see Base Elements Overview.
