Remarks

Classes such as TransformPatternIdentifiers are the identifiers for the Windows Runtime implementation of a common provider pattern for Microsoft UI Automation. You might use these identifiers if you are implementing a Windows Runtime custom automation peer that reports support for ITransformProvider in its GetPattern implementation. These identifiers are needed for the RaisePropertyChangedEvent calls that you make from control code that references your own peer, or for FindItemByProperty in an items container peer.

This same pattern is usually exposed to clients in a different way, depending on which technology they use to implement the client and examine the Microsoft UI Automation tree. ITransformProvider is also presented as a Component Object Model (COM) interface.
