The following example shows how to use the WorkflowServiceHost class.
Console.WriteLine("Starting up..."); 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); Console.WriteLine("To terminate press ENTER"); Console.ReadLine(); } catch (Exception ex) { Console.WriteLine("Service terminated with exception {0}", ex.ToString()); } finally { host.Close(); }
