>>NHibernate is doing the loading of log4net so as long as it has a reference to log4net your application doesn't have to worry about it. When you compile your app you will see the log4net dll copied over to your application's bin directory.

Factory loading...

You use a provider interface to code against in your application and it then needs the actual classes only if they are actually loaded and required.

I do this same thing with things like data providers that I'm not using like Oracle or Vista Db - they only get pulled in once I enable the support. This can be done in code (if you have interfaces) or if you're lazy with compiler switches (which is not a runtime solution obviously).
