A pull request was submitted last year that delegates finding log4net to .Net.
https://github.com/nhibernate/nhibernate-core/pull/15 It was not merged at the time because there was some compatibility concerns since if log4net was installed in the GAC, NHibernate would now suddenly find this. Someone mentioned delaying it until the next major version. Since we are now aiming for 3.3, perhaps we should try to make a decision on this. Since we are only trying to load log4net if no other logging framework has been configured, I think the proposed change would be ok. Also, before the introduction of the logging abstraction, log4net would always be loaded even when not configured. /Oskar
