State Machine Communication Sample

This sample demonstrates how to use events that are sent from the host application to set the state in a state machine workflow.

In the sample, a simple local service called EventService is used to send an event to the workflow called SetState. When the workflow starts, it immediately idles and listens for the SetState event by using a HandleExternalEventActivity activity. When the event is raised by the host, the workflow resumes execution, sets the state to the workflow's completed state, and exits.
