    Log4Net does not get that much attention any more. From my understanding it served as an alternative for Log4J, but today better and more modern solutions have been created. I migrated a codebase over to .NET Core a couple of years ago, and it seemed that Log4net had issues running on Linux because of kernel calls inside their codebase. If you look at the version history on NuGet, it had just 3 patch releases last year. As an alternative, I would suggest to check out NLog.
