Hosting WCF Service with netTcpBinding on IIS7

 I hosted my wcf service with wsHttpBinding as well as netTcpbinding.While I hosted with netTcpBinding on IIS 7 follwing things I have considered, hope it will be useful for others also . 

Web.Config should have following configuration settinggs to hosting WCF service on IIS7(WAS):

    <bindings>
      <netTcpBinding>
        <binding name="tcpbinding" portSharingEnabled="true">
          <security mode="None"></security>
          <!--<security mode="Transport">
            <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign"/>
            <message clientCredentialType="Windows"/>
          </security>-->
        </binding>
       </netTcpBinding>
    </bindings>
