Remarks

The KeyboardDevice supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code.

For keyboard related input, use the Keyboard class. The Keyboard class represents the keyboard to an application and provides methods, properties, and events that reflect the state of the keyboard.

The Keyboard class delegates to the appropriate KeyboardDevice.

Each InputDevice object represents one particular input device. For example, if there are two mice, there will be two InputDevice objects.
