Response is always null when send request to BizTalk WCF Service

Question

1. i have created on orchestration with 2 ports. 1st is request-response two way port which is receiving request from my web service. 2nd is request-response two way port which is forwarding that request to another web service to retrieve data.

2. then i have deployed the project in biztalk administration.

3. project is published as wcf service in IIS

4. i have added the reference of wcf service to my asp.net project.

Issue: when i am sending request from my asp.net project to biztalk wcf service it is working fine. forwarding that request to the next service and reeving data from there.

if i am writing data on disk in file in my port configuration its fine but in my response back to my request its always null.

please help me to solve this issue.

string strRequest = "Here is my xml"

using (OrchestrationRTA2_Port_App2Client btsSvc = new OrchestrationRTA2_Port_App2Client())
{

var result = btsSvc.Operation_1( new RequestRoot

                    {
                        RequestPacket = strRequest
                    });
                    string str = "";
                    if (result != null)
                        str = result.ToString();

                    btsSvc.Close();
                }

Answer 1

This issue can be caused if the Receive Pipeline on your BizTalk Two Way Receive port (the one created when you exposed your Orch as a WCF service) is set to Passthrough, instead of Xml. Can you check this?
