对于一些疑难杂症，我们无法根据经验去判断的时候，只能用日志来表述一切

 

下面看看对WCF 的日志配置

在Configuration中插入以下节点

 

 <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>
             <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>
         </sources>
         <sharedListeners>
             <add initializeData="app_messages.svclog"
               type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
               name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp">
                 <filter type="" />
             </add>
             <add initializeData="app_tracelog.svclog"
               type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
               name="ServiceModelTraceListener" traceOutputOptions="Timestamp">
                 <filter type="" />
             </add>
         </sharedListeners>
         <trace autoflush="true" />
     </system.diagnostics>

 

 

在System.serviceModel 中插入以下节点

 

 <diagnostics wmiProviderEnabled="true" performanceCounters="All">
   <messageLogging logMalformedMessages="true" logMessagesAtTransportLevel="true" />
  </diagnostics>

 

 

ok ， 当然还可以用配置管理器来配置  WCF 的日志记录。
