Definition

Namespace:
System.Windows.Automation.Peers
Assembly:
PresentationCore.dll

Remarks

When UI Automation queries the root of a Windows Presentation Foundation (WPF) application about an element, the root returns the UI Automation peer for that element. The peer also responds to UI Automation queries about its corresponding element.
