Assembly: System.Windows (in System.Windows.dll)
This implementation does nothing more than calling GetAutomationIdCore.
In general, a UI Automation AutomationID is more relevant to automation scenarios, whereas a UI Automation Name is more relevant to accessibility scenarios.
In practical terms, the value of the UI Automation identifier is generally the AutomationId property. If that property is not set, the value is the Name property. However that behavior is not yet implemented at this level. See FrameworkElementAutomationPeer.GetAutomationIdCore.
