public interface IWpfKeyboardTrackingService

The IWpfKeyboardTrackingService type exposes the following members.

Public methodBeginTrackingKeyboardStarts tracking the keyboard.
Public methodEndTrackingKeyboardStops tracking the keyboard.

Keyboard tracking is necessary because some hosts, such as VisualStudio, do their own keyboard handling, causing inconsistent behavior with WPF elements even when they have keyboard focus. By tracking the keyboard, all keyboard events will be routed to WPF first, giving focused WPF controls a chance to handle keyboard events in a consistent manner.
