    I highly recommend log4net.

    An application log records whatever you tell it to record. One big advantage is that you can choose what information to record, so you can log system state, current user, and other parameters of your choosing. The event log is not as flexible. Logging frameworks typically let you record events that happen at different levels, but it’s up to you to define what those levels mean in your code. The log level is set through configuration, so it is DEBUG on our dev system and WARN on our prod system. These are my definitions for the log4net levels:

    DEBUG - Tracing, etc., use at will
INFO - System state info, important/useful info that you don't care to see in the production log
WARN - Handled exceptions, rare events, unusual code branches taken
ERROR - Caught but unhandled exceptions
FATAL - Only used in global handler
