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>
