dispatchOperation.Formatter NULL when call soap service - wcf

Question

I have IDispatchMessageFormatter implementation
class ServerMessageFormatter : IDispatchMessageFormatter
{
private IDispatchMessageFormatter Formatter;
public ServerMessageFormatter(IDispatchMessageFormatter formatter)
{
this.Formatter = formatter;
}
public void DeserializeRequest(System.ServiceModel.Channels.Message message, object[] parameters)
{
Formatter.DeserializeRequest(message, parameters);
}
}
and in OperationBegavior
public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation)
{
ServerMessageFormatter Formatter = new ServerMessageFormatter(dispatchOperation.Formatter);
dispatchOperation.Formatter = Formatter;
}
and call soap service
GetInfoRequest message = CheckedFields;
string soap = #"<?xml version=""1.0"" encoding=""utf-8""?>
<soap12:Envelope xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">
<soap12:Header>
<Action soap12:mustUnderstand=""1"" xmlns=""http://www.w3.org/2005/08/addressing"">ServiceModel/IService/GetSoapData</Action>
</soap12:Header>
<soap12:Body>
<GetInfoRequest xmlns=""ServiceModel"">
<Data xmlns:d4p1=""http://schemas.microsoft.com/2003/10/Serialization/Arrays"" xmlns:i=""http://www.w3.org/2001/XMLSchema-instance""/>
</GetInfoRequest>
</soap12:Body>
</soap12:Envelope>";
XmlSerializer serializer = new XmlSerializer(typeof(GetInfoRequest));
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://dev.add.renault.com/Service.svc/soap");
MemoryStream stream1 = new MemoryStream();
serializer.Serialize(stream1, message);
stream1.Position = 0;
StreamReader sr = new StreamReader(stream1);
string t = sr.ReadToEnd();
t = t.Remove(0, 22).Trim();
t = string.Format(soap, t);
ASCIIEncoding encoding = new ASCIIEncoding();
request.Timeout = 99999999;
request.ContentLength = t.Length;
request.Method = "POST";
request.ContentType = "application/soap+xml; charset=utf-8";
request.Accept = "application/soap+xml; charset=utf-8";
using (Stream stm = request.GetRequestStream())
{
using (StreamWriter stmw = new StreamWriter(stm))
{
stmw.Write(t);
}
}
var response = (HttpWebResponse)request.GetResponse();
var abc = new StreamReader(response.GetResponseStream());
Problem is that when I call my REST service and set breakpoint in DeserializeRequest I see that Formatter has set value from Operation Behavior. But when call soap service my Formatter has null value and deserialization was aborted. Why when calling soap I have that problem? Any idea?
Unfortunatelly I can not fire breakpoint in Operaration Behavior and see what value have dispatchOperation...

You don't show how you configure your service to add your custom IDispatchMessageFormatter extension. So just taking a guess here, you may be adding it only to the webHttpBinding endpoint and not to the soap based binding endpoint. If you are using the WebHttpBehavior methods (GetRequestDispatchFormatter & GetReplyDispatchFormatter) then this won't apply to your soap endpoints. This blog post has a good overview of how to use IDispatchMessageFormatter with webHttpBinding and basicHttpBinding.
EDIT:
The specific code in the article that shows how to add the a custom message formatter to the basicHttpBinding is below. Just prior to that section, he explains why this approach is necessary.
//--- snipped ---//
string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));
ServiceEndpoint endpoint = host.AddServiceEndpoint(typeof(ITest), new BasicHttpBinding(), "");
endpoint.Contract.Operations.Find("Add").Behaviors.Add(new MyOperationBehaviorAttribute());
host.Open();
