Assembly: PresentationCore (in PresentationCore.dll)
If your class matches one of the known control types, override the method to return that ControlType. Note that although the existing ControlType values are generally associated with 2D controls, the ControlType indicates a control's functionality, not its appearance. So if your UIElement3D invokes an action when the user clicks it, you probably want GetHelpTextCore to return ControlType.Button.
