WCF trace file keeps getting corrupted?

.net, c#, iis, trace, wcf

Solution

Per John's answer, you can use Trace.AutoFlush to flush the file after every write. Something along the lines of this example ...

<system.diagnostics>
   <sources>
       <source name="UserTraceSource" switchValue="Warning, ActivityTracing" >
          <listeners>
              <add name="xml"
                 type="System.Diagnostics.XmlWriterTraceListener"
                 initializeData="C:\logs\UserTraces.svclog" />
          </listeners>
       </source>
   </sources>
   <trace autoflush="true" /> 
</system.diagnostics>

Problem

I enabled message tracing on a WCF service. it traces a couple of messages and then it stops, when I try to open the trace in TraceViwer it gives me an error on the last message that got logged, or doesn't even open the file duo to different error everytime. I can't even delete the corrupt file unless i run a resetiis since the file is being used! here is my trace config. ``` <system.diagnostics> <sources> <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="C:\Logs\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> <system.serviceModel> <diagnostics> <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" /> </diagnostics> </system.serviceModel> ```
