Log Request/Response xml in WCF Service

In this post, I will explain you how to log the Request/Response xml of the WCF service.

At the Client end, which is consuming the WCF service, in its config file, add the following nodes:

<configuration>  

     <system.diagnostics>

        <sources>

           <source name="System.ServiceModel.MessageLogging"  switchValue="Warning,ActivityTracing">

              <listeners>

                 <add name="ServiceModelMessageLoggingListener">

                    <filter type="" />

                 </add>

              </listeners>

           </source>

        </sources>

        <sharedListeners>

           <add initializeData="c:\WCFClientLogs.svclog" 

                   type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0,                            Culture=neutral, PublicKeyToken=b77a5c561934e089"

                   name="ServiceModelMessageLoggingListener" 

                   traceOutputOptions="LogicalOperationStack, DateTime, Timestamp, 

                        ProcessId, ThreadId, Callstack">

              <filter type="" />

           </add>

        </sharedListeners>

     </system.diagnostics>

     <system.serviceModel>

        <behaviors configSource=".\Configuration\ServiceModeBehaviors.config" />

        <bindings configSource=".\Configuration\ServiceModelBindings.config" />

        <client configSource=".\Configuration\ServiceModelClient.config" />

        <diagnostics wmiProviderEnabled="true" performanceCounters="All">

           <messageLogging logEntireMessage="true" logMalformedMessages="true"

              logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" />

           <endToEndTracing propagateActivity="true" activityTracing="true"

            messageFlowTracing="true" />

        </diagnostics>

        <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

     </system.serviceModel>

</configuration>

This will log the information in the following location with name : C:\WCFClientLogs.svclog
