Can't get netTcpBinding requests to show up in Fiddler

c# wcf fiddler nettcpbinding

I have a WCF service that has two endpoints. One with basicHttpBinding and one with netTcpBinding. Here is my config...

<services>
      <service name="SomeService.Service">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
          name="EndPointHttp" contract="SomeService.IService" />
        <endpoint address="" binding="netTcpBinding" bindingConfiguration=""
          name="EndPointTcp" contract="SomeService.IService" />
        </service>
</services>

However, when I consume the service I am trying to compare the difference between to two requests. So I am running fiddler to do this. I can see the basicHttpBinding requests in Fiddler but I can't get the net.tcp:// requests to show up. What can I do to see this traffic?

Fiddler is a HTTP proxy, so it will only capture requests which use HTTP protocol - it will not capture requests made using socket directly. You can use the Network Monitor or some other low-level capture tool to do that, but the interface is not as nice as the one you may be used to with Fiddler.

Also, as pointed out in another answer by Ladislav Mrnka, you'll be looking at the binary bytes for the .NET Message Framing and the binary XML encoding, so unless you're familiar with them most of the capture will look like gibberish.
