Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Establishes the common events and also the event-related properties and methods for basic input processing by Windows Presentation Foundation (WPF) elements.

Remarks
Important
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.
