NHibernate doesn't have the concept of a pluggable logger. Can't you just put your changed FileAppender in its own assembly and use that? You'd probably have to copy and paste the code from log4net's FileAppender but that might save you from recompiling either library.

We're also using NHibernate 1.2 in one of our apps. It's compiled against log4net 1.2.10. I attempted to recompile 1.2.10 w/ my changes, but because of strong naming, the precompiled NHibernate will not use this new version of the log4net.dll. Is there any way around this besides recompiling NHibernate against the new log4net.dll ? Thanks, Steve
