GenericRootAutomationPeer Class

Exposes HwndSource types to UI Automation.

Namespace:  System.Windows.Automation.Peers
Assembly:  PresentationCore (in PresentationCore.dll)

public class GenericRootAutomationPeer : UIElementAutomationPeer
You cannot directly create an instance of this class in XAML.

GenericRootAutomationPeer is used as a peer for HwndSource when it contains the following tree:

HwndSource->Visual->2 UIElement objects

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 GenericRootAutomationPeer 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.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
