External Data Event Args

Summary

Represents an event that is defined on a local service interface. An interface marked with ExternalDataExchangeAttribute must use an EventArgs type that derives from ExternalDataEventArgs in order to allow that event to be handled in workflow with a HandleExternalEventActivity.

If you are using StateWorkflows you will need to set the WaitForIdle property to true. Failing to do so can result in events getting lost or similar unpredictable event reception.
