Apache log4net

Apache log4net is the C# counterpart of Java's Log4J.

log4net works with both the .NET framework and the Mono project and can be used to add a logging, tracing, and debugging component to your .NET-based applications.

Inspired and closely modeled after the 1.x branch of the Log4J project, this toolkit will help developers add a multi-purpose logger to C# software and get insightful debug information for the code a programmer might be working on.

log4net supports outputting to various locations and formats, is easy to configure via XML files, comes with support for dynamic configurations that change themselves at runtime, and just like the original Log4J it can also be extended via plugins.

Performance is good and documentation is included with the standard package.
