Description

I'm using netstandard version of the logger which is constantly fails wit error:

System.MethodAccessException: Attempt by security transparent method 'log4net.Appender.RollingFileAppender.ActivateOptions()' to access security critical method 'System.Threading.Mutex..ctor(Boolean, System.String)' failed.

Assembly 'log4net, Version=2.0.8.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.
 at log4net.Appender.RollingFileAppender.ActivateOptions()
 at Log.CreateTimestampedFileAppender(LoggingSettings settings)
 at Log.InitForComponent(String componentName, LoggingSettings settings)
...

My logger assembly is a netstandard asembly which is using by .net framework console app.

Error disappears, when I'm replacing log4net netstandard1.3 version by net45-full
