How to make Action blank in WCF service, as client need blank SoapAction=""?

I have a client they gave some WSDL, I generated some code from their WSDL using svcutil tool. [System.ServiceModel.OperationContractAttribute(Action="")] but it is not allowed in WCF. How I can make this Action a blank string?

Solution

  • The following worked for me: from here

    Download the Microsoft WCF examples. Add the following files to your project from WF_WCF_Samples\WCF\Extensibility\Interop\RouteByBody\CS\service

    DispatchByBodyOperationSelector.cs
DispatchByBodyBehaviorAttribute.cs

    Add the following attributes to your interface (next to your ServiceContract)

    XmlSerializerFormat
DispatchByBodyBehavior

    Add the following to your service interface

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

    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);
}
