خطا در اتصال SOAP Client

سلام دوستان

به یک سرویس SOAP که میخواهیم متصل شویم ، خطاهای زیر رو دریافت می کنیم:

1- در حالت basicHttpBinding خطای version میگیریم که ظاهرا باید Soap12 تنظیم بشه.

System.ServiceModel.CommunicationException: 'Unrecognized message version.'

2- برای دادن ورژن ، تنظیم رو روی customBinding میزاریم و خطای زیر رو میگیریم :

System.ServiceModel.ProtocolException: 'The content type text/xml; charset=utf-8 of the response message does 
not match the content type of the binding (application/soap+xml; charset=utf-8). If using a custom encoder,
 be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response were:

تنظیمات App.config به این صورت هستند :

<system.serviceModel>

  <bindings>

    <basicHttpsBinding>
      <binding name="BasicHttpBinding_IManSVC" >
        <security mode="Transport" />
      </binding>
    </basicHttpsBinding>

   <customBinding>
    <binding name="CustomBinding_IManSVC" >
       <textMessageEncoding  messageVersion="Soap12"/>
       <httpTransport />
    </binding>
   </customBinding>

</bindings>

  <client>

    <endpoint address="https://xyz/ManSVC"
      binding="basicHttpsBinding" bindingConfiguration="BasicHttpBinding_IManSVC"
      contract="IManiSVC" name="BasicHttpBinding_IManSVC" />

    <endpoint address="http://xyzl/ManSVC"
              binding="customBinding" bindingConfiguration="CustomBinding_IManSVC"
              contract="IManSVC" name="CustomBinding_IManSVC" />

 </client>

</system.serviceModel>
