Hello, It seems that it is almost impossible to add any logging with Hangfire (Net40). It is very confusing, which versions to use to configure the logger as per the help article [http://docs.hangfire.io/en/latest/deployment-to-production/adding-logging.html](http://docs.hangfire.io/en/latest/deployment-to-production/adding-logging.html). I am using the Hangfire (.net4) which uses the Common.Logging (2.2.0) which Nlog and Nlog adapters should i use? We are using the Log4Net and it would be nice if I know which version of Log4Net are compatible. Log4Net adapters are using the Common.Logging \> = 2.3.1 and getting compile error… Have anyone configured it? ---

.NET 4.0 is not officially supported by Hangfire yet. Those packages on NuGet are made by [@phillcampbell](https://github.com/phillcampbell). Hangfire 1.3.0 will use another library for logging purposes, but I don’t know whether Phill will release a new version, it is hard to merge it. ---
