I have to connect to a legacy web service.
In visual studio, if I do a Add Service Reference, then enter the url of the WSDL file on server. My service shows up, and I write the code against it. But when I run the code I get this error:
System.ServiceModel.CommunicationException: The envelope version of the incoming message (Soap12 (http://www.w3.org/2003/05/soap-envelope)) does not match that of the encoder (Soap11 (http://schemas.xmlsoap.org/soap/envelope/)). Make sure the binding is configured with the same version as the expected messages.
My app.config looks like this:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="LoginServiceSoap" />
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://server/Service.asmx" binding="basicHttpBinding"
bindingConfiguration="LoginServiceSoap" contract="Stuff.Login.LoginServiceSoap"
name="LoginServiceSoap" />
</client>
</system.serviceModel>
However, I am able to communicate with the service fine, if I add a 'Web Reference'. But my understanding is that I am supposed to use Service References now, instead of WebReferences. I am assuming I have something wrong in my above config.
Or am I forced to use a Web Reference, because of the type of service I am connecting to?
Sheamus,
You could (theoretically) add the version number to the binding definition.
With, of course, the right value for your service.
So it would look more like:
Hope this helps you do things your way.
