Пытаюсь понять как связаться через https
с объектом который захостил под IIS.
Мне нужна сквозная авторизация и защищенный канал связи.

пробую так

web.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.runtime.remoting>
    <application>
      <service>
        <wellknown mode="Singleton" type="Server.ServerProxy, Server" objectUri="Service.soap" />
      </service>
      <channels>
        <channel ref="http" useDefaultCredentials="true" />
      </channels>
    </application>
  </system.runtime.remoting>
  <system.web>
    <compilation>
      <assemblies>
        <add assembly="System.Runtime.Remoting, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
      </assemblies>
    </compilation>
    <identity impersonate="true"/>
    <authentication mode="Windows"/>
    <authorization>      
      <allow users="*" />
    </authorization>
  </system.web>
<system.net>
   <settings>
      <servicePointManager checkCertificateName="true" />
   </settings>
</system.net>
</configuration>

код вызова такой

            X509Certificate x509 = GetCert("testCert.cer");
            X509CertificateCollection xcol = new X509CertificateCollection();
            xcol.Add(x509);

            ISimpleObject iService = null;

            object remoteObject = null;
            try
            {
                remoteObject = RemotingServices.Connect(typeof(ISimpleObject),
                   "https://localhost/TIservice/Service.soap");

                iService = remoteObject as ISimpleObject;
                IDictionary dict = ChannelServices.GetChannelSinkProperties(remoteObject);
                dict["clientcertificates"] = xcol;
                dict["credentials"] = CredentialCache.DefaultCredentials;
                dict["connectiongroupname"] = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

                MessageBox.Show(iService).GetString();
            }
            catch (WebException we)
            {
                MessageBox.Show(we.Messae);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Messae);
            }

Получаю WebException
The underlying connection was closed: An unexpected error occurred on a send.
Authentication failed because the remote party has closed the transport strea.

Чего не хватает не пойму?
Искал решение долго но так и не нашел рабчего варианта.
