Exposes HwndSource types to UI Automation.
Assembly: PresentationCore (in PresentationCore.dll)
is used as a peer for HwndSource when it contains the following tree:
Because only UIElement types have peers, and visuals are not UIElement types, a common parent does not exist in the UI Automation tree for the UIElement types. UI Automation expects a single root peer from the application; therefore, Microsoft .NET Framework creates a for the HwndSource in order to serve as a single root peer to parent peers for the two UIElement types.
Typically, the root peer is a WindowAutomationPeer.
