XML : WCF WebHttp service for both XML and JSON choose serializer based on endpoint address

I'm trying to make a WCF RESTful web service which will return both XML and JSON. The problem is that it's working but for XML serialization it's ignoring the XML attributes.

As you can see in the endpoint configuration I have two address like xml and json.

So I access the url like -

For XML -

  http://localhost:59310/TestService.svc/xml/GetResponse    

For JSON -

  http://localhost:59310/TestService.svc/json/GetResponse    

Now I would want to use the DataContractFormat when I access the JSON url and use XmlSerializerFormat for XML url. How can I achieve this. Please help.

This is the response class with XML attributes.

  namespace WCFMultiFormatTest  {      [XmlRoot(ElementName = "RESPONSE")]      public class Response      {          [XmlAttribute(AttributeName = "MESSAGE")]          public string Message { get; set; }      }        [XmlRoot(ElementName = "TEST")]      public class Root      {          [XmlElement(ElementName = "RESPONSE")]          public List<Response> Response { get; set; }      }  }    

This is the service implementation class(svc).

  namespace WCFMultiFormatTest  {      [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Multiple)]      [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]      public class TestService : ITestService      {          public Root GetResponse()          {              Root r = new Root();                r.Response = new List<Response>();                Response r1 = new Response()              {                  Message = "Hello"              };                Response r2 = new Response()              {                  Message = "World"              };                r.Response.Add(r1);              r.Response.Add(r2);                return r;          }      }  }    

This is the service contract interface.

  namespace WCFMultiFormatTest  {      [ServiceContract]      public interface ITestService      {          [OperationContract]                  [WebInvoke(Method = "GET", UriTemplate = "/GetResponse")]          Root GetResponse();      }  }    

This is the service configuration in web.config.

  <system.serviceModel>      <bindings>        <webHttpBinding>          <binding name="WebHttpBinding_TestService" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" useDefaultWebProxy="true">            <readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>            <security mode="None">              <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>            </security>          </binding>        </webHttpBinding>      </bindings>      <behaviors>        <endpointBehaviors>          <behavior name="JSONRestBehavior">            <webHttp defaultOutgoingResponseFormat="Json" />          </behavior>          <behavior name="XMLRestBehavior">            <webHttp defaultOutgoingResponseFormat="Xml" />          </behavior>        </endpointBehaviors>        <serviceBehaviors>          <behavior>            <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />            <serviceDebug includeExceptionDetailInFaults="false" />          </behavior>          <behavior name="TestServiceBehavior">            <serviceThrottling maxConcurrentCalls="300" maxConcurrentSessions="100" maxConcurrentInstances="2147483647" />            <serviceMetadata httpGetEnabled="true" />            <serviceDebug includeExceptionDetailInFaults="true" />          </behavior>        </serviceBehaviors>      </behaviors>      <services>        <service behaviorConfiguration="TestServiceBehavior" name="WCFMultiFormatTest.TestService">          <endpoint address="XML" binding="webHttpBinding" bindingConfiguration="WebHttpBinding_TestService" contract="WCFMultiFormatTest.ITestService" behaviorConfiguration="XMLRestBehavior"></endpoint>          <endpoint address="JSON" binding="webHttpBinding" bindingConfiguration="WebHttpBinding_TestService" contract="WCFMultiFormatTest.ITestService" behaviorConfiguration="JSONRestBehavior"></endpoint>        </service>      </services>      <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />    </system.serviceModel>
