The following example shows how to use a ReceiveReply activity. A Send activity is created and added to a Sequence. A ReceiveReply activity is then added to the Sequence to receive the reply from the Send activity.

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
      Content = new SendParametersContent
      {
         Parameters = 
            { 
               { "message", new InArgument<string>(message) }
            }
        }
    };
    workflow = new CorrelationScope
    {
       Body = new Sequence
       {
          Variables = { message, result },
                    Activities =
                    {
                        new WriteLine {
                            Text = new InArgument<string>("Client is ready!")
                        },
                        requestEcho,

                        new WriteLine {
                            Text = new InArgument<string>("Message sent: Hello!")
                        },

                        new ReceiveReply
                        {
                            Request = requestEcho,
                            //parameters for the reply
                            Content = new ReceiveParametersContent                            
                            {
                                Parameters = 
                                {
                                    { "echo", new OutArgument<string>(result) }
                                }
                            }
                        },                                                
                        new WriteLine {
                            Text = new InArgument<string>(env => "Message received: "+result.Get(env))
                        }
                    }
                }
            };
        }
