ASP.NET logging to Apache error_log

Grr, who designed the structure for the ASP.NET documentation? I have been scratching my head for nearly an hour trying to figure out how to place a message in the apache log file.

When you search you come up with 100 line solutions written by M$'s Most Valuable Pricks that show you how to write to windows event logs, send errors as email messages and send them as messages in a bottle. All of them seem to ignore this simple trivial one line solution.
