WSDL first WCF server where client does not send SOAPAction

Question

I am implementing a WCF web service which interacts with a client whose code I do not control. The WSDL was supplied by the client.

I generated C# files from the WSD

Answer 1

The following worked for me (based on this thread):

1. Download the Microsoft WCF examples.
2. Add the following files to your project from WF_WCF_Samples\WCF\Extensibility\Interop\RouteByBody\CS\service
   • DispatchByBodyOperationSelector.cs
   • DispatchByBodyBehaviorAttribute.cs
3. Add the following attributes to your interface (next to your ServiceContract)
   • XmlSerializerFormat
   • DispatchByBodyBehavior

4. Add the following to your service interface

   [OperationContract(Action = "")]
   public void DoNothing()
   {
   }
   

5. For my service the WrapperName and Wrappernamespace are null for all messages. I had to go into DispatchByBodyBehaviorAttribute and edit ApplyDispatchBehavior() to add the following lines to check for this:

    if (qname.IsEmpty) {
        qname = new XmlQualifiedName(operationDescription.Messages[0].Body.Parts[0].Name, operationDescription.Messages[0].Body.Parts[0].Namespace);
    }
