IMessageDispatcherCreateDispatchTarget Method

version: 7.2.1.27

Creates a IDispatchTarget instance to be used in the Subscribe(IDispatchTarget, Int32, Object) and Unsubscribe(IDispatchTarget, Int32, Object) methods.

Note: Client applications must keep IDispatchTarget object references accessible if they want to Unsubscribe from the given IMessageDispatcher, and remove already added Topic subscriptions. IDispatchTarget internal object ID constitutes a unique key. Forgetting to keep a reference to IDispatchTarget objects make subsequent Unsubscribe(IDispatchTarget, Int32, Object) calls impossible.
