Common.Logging.Core has been deprecated

I use the latest version of Common.Logging in my project. When I added your great package to my project, I got a lot of errors because the latest versions of Common.Logging and Common.Logging.Core define essentially the same types. It can be worked around, though, by definig an alias for Common.Logging.Core. Removing the dependency on Common.Logging.Core is a much cleaner approach IMO.
