INTRODUCTION

Windows Communication Foundation (WCF) does not have the functionality to send secured messages and then receive unsecured responses, or to send unsecured messages and receive secured responses. The hotfix that is described in this article adds a new enableUnsecuredResponse attribute. The default value of the enableUnsecuredResponse attribute is false. If you set the value of this attribute to true, the following new features are enabled in WCF:
  • WCF clients can accept unsecured responses even if the outgoing messages are secured by using the Secure Socket Layer (SSL) protocol to sign the message body.
  • WCF services can send unsecured responses that have no security header in SOAP envelopes even if the request is secured.
Note The enableUnsecuredResponse attribute only applies only to the CustomBinding type.

serviceSbe.EnableUnsecuredResponse = true;
serviceBec.Add(serviceSbe);
serviceBec.Add(new TextMessageEncodingBindingElement());
serviceBec.Add(new HttpTransportBindingElement());
Binding serviceBinding = new CustomBinding(serviceBec);

ServiceHost serviceHost = new ServiceHost(typeof(RequestReply));
…
serviceHost.Open();
Client
BindingElementCollection clientBec = new BindingElementCollection();
SecurityBindingElement clientSbe = SecurityBindingElement.CreateUserNameForCertificateBindingElement();
clientSbe.EnableUnsecuredResponse = true;
clientBec.Add(clientSbe);
clientBec.Add(new TextMessageEncodingBindingElement());
clientBec.Add(new HttpTransportBindingElement());
Binding clientBinding = new CustomBinding(clientBec);

IRequestReply channel = cf.CreateChannel();
