          <baseAddresses>
            <add baseAddress="net.tcp://192.168.200.1/myservice"/>
          </baseAddresses>
        </host>
        <endpoint address="" binding="netTcpBinding" contract="WcfService.IService" bindingConfiguration="noSecurity"/>
        <endpoint address="mex" binding ="mexTcpBinding" contract="IMetadataExchange"></endpoint>
