title: Enterprise Library Fluent API and Rolling Log Files Not Rolling
body: <p>I am using the Fluent API to handle various configuration options for Logging using EntLib.</p>
  
  <p>I am building up the loggingConfiguration section manually in code. It seems to work great except that the RollingFlatFileTraceListener doesn't actually Roll the file. It will respect the size limit and cap the amount of data it writes to the file appropriately, but it doesn't not actually create a new file and continue the logs.</p>
  
  <p>I've tested it with a sample app and the app.config and it seems to work. So I'm guess that I am missing something although every config option that seems like it needs is there.</p>
  
  <p>Here is the basics of the code (with hard-coded values to show a config that doesn't seem to be working):
          //Create the config builder for the Fluent API
                  var configBuilder = new ConfigurationSourceBuilder(); </p>
  
  <pre><code>            //Start building the logging config section                 
              var logginConfigurationSection = new LoggingSettings("loggingConfiguration", true, "General");                 
              logginConfigurationSection.RevertImpersonation = false;
              var _rollingFileListener = new RollingFlatFileTraceListenerData("Rolling Flat File Trace Listener", "C:\\tracelog.log", "----------------------", "",
                              10, "MM/dd/yyyy", RollFileExistsBehavior.Increment,
                              RollInterval.Day, TraceOptions.None,
                              "Text Formatter", SourceLevels.All);
  
  
              _rollingFileListener.MaxArchivedFiles = 2;
  
              //Add trace listener to current config
              logginConfigurationSection.TraceListeners.Add(_rollingFileListener);
  
              //Configure the category source section of config for flat file
              var _rollingFileCategorySource = new TraceSourceData("General", SourceLevels.All);
  
              //Must be named exactly the same as the flat file trace listener above.
              _rollingFileCategorySource.TraceListeners.Add(new TraceListenerReferenceData("Rolling Flat File Trace Listener"));
  
              //Add category source information to current config
              logginConfigurationSection.TraceSources.Add(_rollingFileCategorySource);          
  
              //Add the loggingConfiguration section to the config.
              configBuilder.AddSection("loggingConfiguration", logginConfigurationSection);
  
              //Required code to update the EntLib Configuration with settings set above.
              var configSource = new DictionaryConfigurationSource();
              configBuilder.UpdateConfigurationWithReplace(configSource);
  
              //Set the Enterprise Library Container for the inner workings of EntLib to use when logging
              EnterpriseLibraryContainer.Current = EnterpriseLibraryContainer.CreateDefaultContainer(configSource);
  </code></pre>
  
  <p>Any help would be appreciated!</p>
