Exercise 2: Create the Simple Order Form Application

In this exercise, you define an interface that is used to enable communication between the state machine workflow and the Simple Order Form application.

The OrderProcessingWorkflow state machine contains three states:

• The WaitingForOrder state is the workflow's InitialStateName property value. It is entered when the host application raises a predefined event. In this project, the event signifies a new order submission.

• The OrderProcessing state simulates the processing of an order by sending a status message back to the host application.

• The OrderCompleted state is the final state.
