Have you tried an assembly rebind to force resolution to 2.0.9?

Hi Davyd,
The weird thing is everything had been working fine with same
configuration, framework version 4.6, etc. and all I did was update the
nuget package for log4net from 2.0.8 to 2.0.9. After that IIS w3wp process
along with perfmon.dll process on the deployment server crashed when the
application was launched. No error logs were reported even when I set the
internal debug to true, nothing. But then, if I revert the nuget package
back to 2.0.8, everything is normal again including the logs with the
internal debugging turned on. So, it makes me think that maybe the 2.0.9
version is missing a dependency library or something but I couldn't find
anything online to that effect.

Subject: RE: issues with log4net 2.0.9 under IIS for projects using .net
framework 4.5+
Hi Joseph
I've performed a (rather belated) upgrade to log4net 2.0.9 on a work
project targeting net462 and, apart from having to perform some assembly
rebinds to handle dependencies which expect log4net 2.0.8, it's working
fine with an ado.net appender and a rolling log file appender, so I'd
really like to know more about your environment & configuration.
