WorkflowService service = CreateService();
Uri address = new Uri(Constants.ServiceBaseAddress);
WorkflowServiceHost host = new WorkflowServiceHost(service, address);

try
{
    Console.WriteLine("Opening service...");
    host.Open();

    Console.WriteLine("Service is listening on {0}...", address);
