An item with the same key has already been added. IIS WCF Rest

I am hosting WCF Rest service with my Asp.net Application, and asp.net compatibility mode is on ,it is working fine when I run app from visual studio but when I in IIS7 I get error while accessing the End Point says "An item with the same key has already been added." MY Service Cod is.

  [ServiceContract]
    [AspNetCompatibilityRequirements
    (RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

    public class RestService
    {

        [OperationContract]
        [WebGet(UriTemplate = "Site/{Id}", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
        public Site GetSite(string Id)
        {
            return new Site(1);
        }
}

and global ASCX is

   protected void Application_Start ()
        {
            RouteTable.Routes.Add(new ServiceRoute("Rest", new WebServiceHostFactory(), typeof(RestService)));

       }

and web.config

     <system.serviceModel>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

        <standardEndpoints>
               <webHttpEndpoint>
                    <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="false"/>
               </webHttpEndpoint>


        </standardEndpoints>
      </system.serviceModel>

Note Every things working fine in VS2010 Mode but getting error in while Hosting IIS 7 and accessing http://example.com/rest/site/2 any Suggestion Please ?
