WCF Service debuging technique from client

While implementing any WCF service in any client application, you may find lots of issue, here i share some experience how you can get to know whats going wrong at service end!




You just need to turn on Tracing and Messging on WCF server





As a result you see the following set of tags has been added in your web config file.

< system.diagnostics >
< sources >
< source name="System.ServiceModel" switchValue="Warning, ActivityTracing"
propagateActivity="true" >
< listeners >
< add type="System.Diagnostics.DefaultTraceListener" name="Default" >
< filter type="" / >
< /add >
< add name="ServiceModelTraceListener" >
< filter type="" / >
< /add >
< /listeners >
< /source >
< source name="System.ServiceModel.MessageLogging" switchValue="Warning, ActivityTracing" >
< listeners >
< add type="System.Diagnostics.DefaultTraceListener" name="Default" >
< filter type="" / >
< /add >
< add name="ServiceModelMessageLoggingListener" >
< filter type="" / >
< /add >
< /listeners >
< /source >
< /sources >
< sharedListeners >
< add initializeData="F:\MyWCFFolder\Web_tracelog.svclog"
type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
name="ServiceModelTraceListener" traceOutputOptions="Timestamp" >
< filter type="" / >
< /add >
< add initializeData="F:\MyWCFFolder\Web_messages.svclog"
type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp" >
< filter type="" / >
< /add >
< /sharedListeners >
< /system.diagnostics >
