I have two separate xml files I use for configuring log4Net. One is to log to a file, the other is to log just to the console. I control which file gets read in my Global.asax.cs file in the Application_Start() method:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
//Initialize Log4Net
XmlConfigurator.Configure(new System.IO.FileInfo("C:\\temp2\\DataTables_Examples\\DataTables_Examples\\Console.config"));
log.Info("Initializing Log4Net...");
Debug.WriteLine("MvcApplication - Initializing Log4Net...");
}
When I run my webapp using the xml file configured to write to a file, it works perfectly fine giving me the following output:
2014-10-01 13:34:56,596 [6] ERROR CSED.Database

This is just fine. I've deliberately changed the password on the connection string in web.config so that this exception would be thrown. Then I tried to configure log4Net to log to the console and I expected the same output. NOT!
My configuration file for the console looks like this:
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<!-- ConsoleAppender uses PatternLayout -->
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d [%t] %-5p %c %m%n" />
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="ConsoleAppender" />
</root>
</log4net>
</configuration>
Nothing unusual there.
For comparison, this is the config for logging to a file. This works:
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<log4net>
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender" >
<file value="C:\\temp2\\DataTables_Examples\\DataTables_Examples\\log.txt"/>
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d [%t] %-5p %c %m%n" />
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="LogFileAppender" />
</root>
</log4net>
</configuration>
And yet when I run my webapp I get the following:

A first chance exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll
The Console.config file is definitely being read in by log4Net. So why isn't it printing out to console the same as it does when logging to a file? The conversionPattern is the same for both. All I'm getting is the one line at the bottom of the console. I'm missing something somewhere.
