Trying to upgrade to Epi 11 and got a conflict between the CommonFramework, which uses an old NHibernate and is stuck on log4net 1.2 and the Episerver.Logging.Log4net which uses log4net > 2.
The advice in the previous topic (https://world.episerver.com/forum/developer-forum/Problems-and-bugs/Thread-Container/2016/1/could-not-load-file-or-assembly-39log4net-version1-2-10-0/), to downgrade the logging doesn't work because that version is only valid for Epi 10. Can't ditch the CommonFramework because the site is using Community.
