      <service name ="WCFService.ServiceClass" behaviorConfiguration="metadataSupport">
        <endpoint contract ="WCFService.IServiceClass"
        name="NetTcpBinding_IServiceClass"
        binding ="netTcpBinding"
        address ="net.tcp://localhost:8000/TcpBinding"/>
        <endpoint address="net.tcp://localhost:8000/TcpBinding/tcpmex"
        binding="mexTcpBinding"
        contract="IMetadataExchange"/>
      </service>
    </services>
    <bindings>
      <netTcpBinding>
        <binding name ="NetTcpBinding_IServiceClass">
          <security mode="None"></security>
          </binding>
