I have been working on a WCF web service that I finally deployed to our staging server which runs over HTTPS. Everything seemed fine. I was able to hit it and generate the WSDL. However, when I tried running the svcutil.exe on it, I got the following error:
Error: Cannot add the transport element 'httpTransport'. Another transport eleme nt already exists in the binding 'System.ServiceModel.Configuration.HttpTranspor tElement, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken= b77a5c561934e089'. There can only be one transport element for each binding.
Upon investigation, I realized that when deploying a WCF web service over HTTPS, you must set the ‘Security’ mode to ‘Transport.’. Below are the steps to do this:
1. Add the following inside the
<bindings> <wsHttpBinding> <binding name="webBinding"> <security mode="Transport"></security> </binding> </wsHttpBinding> </bindings>
2. Add the following attribute to the
bindingConfiguration="webBinding"
That should be all.
Below is a sample
<system.serviceModel> <services> <service name="MyWebService" behaviorConfiguration="ServiceBehavior"> <!-- Service Endpoints --> <endpoint address="" binding="wsHttpBinding" bindingConfiguration="webBinding" contract="IMyWebService"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <bindings> <wsHttpBinding> <binding name="webBinding"> <security mode="Transport" /> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>
