How to Turn on WCF Tracing in 2 steps

There are two steps to turn on WCF tracing.
First is to add a source as shown below inside 'Configuration' element

<system.diagnostics>

    <trace autoflush="true" />

    <sources>

      <source name="System.ServiceModel.MessageLogging">

        <listeners>

          <add

          name="messages"

          type="System.Diagnostics.XmlWriterTraceListener"

          initializeData="Messages.svclog" />

        listeners>

      source>

    sources>

  system.diagnostics>

 

And second is to put the following inside the 'System.ServiceModel' element to start tracing.

<diagnostics>

      <messageLogging

      logEntireMessage="true"

      logMalformedMessages="true"

      logMessagesAtServiceLevel="true"

      logMessagesAtTransportLevel="false"

      maxMessagesToLog="0x7fffffff"

      maxSizeOfMessageToLog="0x7fffffff"/>

diagnostics>

After that your messages will be logged into a file called Messages.svclog.
