Description

Hi,

Note: this bug is in 2.0.12 even though I cannot select it here.

I got the log4net lib from nuget https://www.nuget.org/packages/log4net/ and it is working fine with 2.0.8, but switching to 2.0.12 prevents the creation of log files and also does not write to existing log files.

The config file is

<log4net>
<root>
<level value="ALL" />

<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="ErrorLogFileAppender" />
