I am trying to write a simple wrapper around log4net for my team, but I cannot get rid of the log4net configuration errors I am getting.
Can someone assist me?

Answered this in my blog http://mperlstein.blogspot.com/2012/04/log4net-configuration-trouble.html
The gist is that log4net uses reflection to update attributes, and Threshold does not exist as a writable property/attribute on the object in question.
Never again
