Wshttpbinding with silverlight5

i have a WCF service and using wsHttpBinding in web config.

create a test certificate from IIS7 and use it as https binding with website

Web config of Service as below

<system.serviceModel><behaviors><serviceBehaviors><behavior name="WsBehaviour"><serviceMetadata httpsGetEnabled="true"/><serviceDebug includeExceptionDetailInFaults="false"/></behavior></serviceBehaviors></behaviors><bindings><wsHttpBinding><binding name="WsBinding"><security mode="Transport"><transport clientCredentialType="None" proxyCredentialType="None" realm=""/><message clientCredentialType="None" algorithmSuite="Default" />        </security>            </binding></wsHttpBinding>    </bindings><services><service name="WsService.Service1" behaviorConfiguration ="WsBehaviour"><endpoint address="https://MachineName.DomainName:8087/WsService/Service1.svc"
      binding="wsHttpBinding" bindingConfiguration="WsBinding" contract="WsService.IService1" ><identity><dns value="localhost" /></identity></endpoint></service></services>  </system.serviceModel>

while open Url in browser it was working perfect, also work perfect in add Service referance to silverlight project . but while call service from application it will gives cross-domain error , i have also include clientaccesspolicy.xml and crossDomain.xml in project, but still face a problem

An error occurred while trying to make a request to URI
'https://MachineName.DomainName:8087/WsService/Service1.svc'. This
could be due to attempting to access a service in a cross-domain way
without a proper cross-domain policy in place, or a policy that is
unsuitable for SOAP services. You may need to contact the owner of the
service to publish a cross-domain policy file and to ensure it allows
SOAP-related HTTP headers to be sent. This error may also be caused by
using internal types in the web service proxy without using the
InternalsVisibleToAttribute attribute. Please see the inner exception
for more details.

Please guide me for any changes in app , also you can share any sample link for the same 

thanks in advance
