C# WCF - communication tracing

In order to diagnostic WCF communication, you can log all WCF activities by using tracing mechanism in .NET application.
You can add the following section in your [app].config file.
After you collected the all trace message you can use a tool called "SvcTraceViewer.exe" to analyse data. This tool can be found the installed SDK tools directory(such as C:\Program Files\Microsoft SDKs\Windows\v6.0\Bin).

<system.diagnostics>
    <trace autoflush="true" />
    <sources>
            <source name="System.ServiceModel"
                    switchValue="Information, ActivityTracing"
                    propagateActivity="true">
            <listeners>
               <add name="sdt"
                   type="System.Diagnostics.XmlWriterTraceListener"
                   initializeData= "Application.e2e" />
            </listeners>
         </source>
    </sources>
</system.diagnostics>
