Silverlight+WCF exception: Expecting application/soap+xml, received text/xml

Question

I have a Silverlight application in which I would like to call a WCF service. When calling the service I receive the following response from the server:

415 Cannot process the message because the content type 'text/xml; charset=utf-8' was not the expected type 'application/soap+xml; charset=utf-8

Has anyone experienced this problem before? Does anyone know which configuration settings I need to adjust? Any information on how to fix this would be appreciated.

Well, you could try using the "Silverlight-enabled WCF Service" template in VS2008, and comparing the differences? I expect that you need to use the basicHttpBinding and are using something more exotic.

For info, here is the web.config section for a default Silverlight/WCF service:

 <system.serviceModel>
  <behaviors>
   <serviceBehaviors>
    <behavior name="MySite.Service1Behavior">
     <serviceMetadata httpGetEnabled="true" />
     <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
  <services>
   <service behaviorConfiguration="MySite.Service1Behavior"
       name="MySite.Service1">
    <endpoint address="" binding="basicHttpBinding"
       contract="MySite.Service1" />
    <endpoint address="mex" binding="mexHttpBinding"
       contract="IMetadataExchange" />
   </service>
  </services>
 </system.serviceModel>
