Assembly: System.Windows (in System.Windows.dll)
The return value for this method in the FrameworkElementAutomationPeer implementation comes from an internal property store, and it returns an empty string. Specific subclasses generally override this method again and return the class name of the owner type for the automation peer. There are two general patterns: return a string that is coded into the implementation, for example "Button"; call Owner.GetType().Name. The latter approach is appropriate if your peer is otherwise suitable for use on subclasses of its primary owner control type. In this case the dynamic value for ClassName saves the control subclasser from having to re-implement that aspect of the automation peer.
