Questions tagged [log4net-appender]

In log4net, an appender is an output destination for a log such as a file, the console, a database or even e-mail.

An appender looks something like this:

<appender name="console" type="log4net.Appender.ConsoleAppender">
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date %level %logger - %message%newline" />
  </layout>
</appender>

This will output any log message you write via the log4net-Logger to the console attached to your application.
