Trouble getting WCF to work with netTcpBinding

Question

Below is my app.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="Indexer">
        <endpoint address="net.tcp://localhost:8000/Indexer/" binding="netTcpBinding"
          bindingConfiguration="TransactionalTCP" contract="Me.IIndexer" />
      </service>
      <service name = "Indexer" behaviorConfiguration = "MEXGET">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8000/"/&gt;
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name = "MEXGET">
          <serviceMetadata httpGetEnabled = "true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <netTcpBinding>
        <binding name="TransactionalTCP"
           transactionFlow="true"
         />
      </netTcpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

For some reason, I cannot get to the WCF service on the machine where I run this. Can any one spot the error? I have netTcpBinding service up and running.

When I had the same running in HTTP it was working fine with the following .config file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="IndexerServiceBehavior">
          <serviceMetadata httpGetEnabled="true" httpGetUrl="http://localhost:8080/Indexer/"/&gt;
          <serviceDebug includeExceptionDetailInFaults="True" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="Indexer" behaviorConfiguration="IndexerServiceBehavior">
        <endpoint address="http://localhost:8080/Indexer/" binding="basicHttpBinding"
            bindingConfiguration="" name="HTTP" contract="IIndexer" />
        <endpoint address="http://localhost:8080/Indexer/MEX/" binding="mexHttpBinding"
            bindingConfiguration="" name="MEX" contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>
</configuration>

I can't really figure out what I'm doing wrong..

Answer 1

You may have to Enable the Net.TCP Port Sharing Service. Quote from MSDN:

Windows Communication Foundation (WCF) uses a Windows service called the Net.TCP Port Sharing Service to facilitate the sharing of TCP ports across multiple processes. This service is installed as part of WCF, but the service is not enabled by default as a security precaution and so must be manually enabled prior to first use. This topic describes how to configure the Net TCP Port Sharing Service using the Microsoft Management Console (MMC) snap-In.

Good luck!

You have, of course, opened up the firewall to let it listen?

If it's any use, here's the binding I successfully used not so long ago:

<services>

  <service name="MyService.MySearch" behaviorConfiguration="ServiceBehavior">
    <host>
      <baseAddresses>
        <add baseAddress="http://mypc:8003/MyService"/&gt;
      </baseAddresses>
    </host>
    <endpoint bindingConfiguration="Binding1"
              binding="netTcpBinding"
              contract="MyService.IMySearch"
              address="net.tcp://mypc:8004/MyService"  />
  </service>
</services>
<bindings>
  <netTcpBinding>
    <binding name="Binding1"
             hostNameComparisonMode="StrongWildcard"
             sendTimeout="00:10:00"
             maxReceivedMessageSize="65536"
             transferMode="Buffered"
             portSharingEnabled="false">
      <security mode="None">
        <transport clientCredentialType="None" />
        <message clientCredentialType="None" />
      </security>
    </binding>
  </netTcpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior">
      <serviceMetadata httpGetEnabled="true" httpGetUrl=""/>
    </behavior>
  </serviceBehaviors>
</behaviors>

There's no security on this binding.

Try using a different port numbers for http and net.tcp binding. Port sharing has a different purpose, to share the same net.tcp port among multiple processes.
