In this final step you create a user interface for interacting with the workflow service.
The following guides you through the basic housekeeping tasks required to get things started.
1. Open the TravelManagerWeb website in Solution Explorer.
Add a Service Reference to the TravelRequestService (right-click the project, Add Service Reference). Navigate to RequestTravel.xamlx or select Discover from the Add Service Reference dialog box. Name this reference TravelRequestSvc. This serves as the WCF proxy to your workflow.
2. Add a regular, project reference to the TravelDataLib. You need this to define the message data contract to send to the travel request service.
