static void CreateClientWorkflow()  
{  
   Variable<string> message = new Variable<string>("message", "Hello!");  
   Variable<string> result = new Variable<string> { Name = "result" };  

   Endpoint endpoint = new Endpoint  
   {  
      AddressUri = new Uri(Microsoft.Samples.WorkflowServicesSamples.Common.Constants.ServiceBaseAddress), Binding = new BasicHttpBinding(),  
   };  

   Send requestEcho = new Send  
   {  
      ServiceContractName = XName.Get("Echo", "http://tempuri.org/"),  
                Endpoint = endpoint,  
                OperationName = "Echo",  
      //parameters for send
