Implementation Notes for the StylusInput APIs
The RealTimeStylus, GestureRecognizer, and DynamicRenderer classes are implemented as COM wrappers and are available only in managed code.
When the RealTimeStylus, GestureRecognizer, or DynamicRenderer object is added as a plug-in to a RealTimeStylus object, the underlying COM objects interact on the COM level. Therefore, directly calling the methods of the IStylusSyncPlugin or IStylusAsyncPlugin interfaces are not supported. Adding the RealTimeStylus, GestureRecognizer, or DynamicRenderer object to the RealTimeStylus object is the only way to access these features.
