No log file is created about microsoft.extensions.logging.log4net.aspnetcore HOT 3 CLOSED

Solution given by @pfx via StackOverflow:

Assuming the configuration gets hooked up; use the log4net.Appender.FileAppender instead of the log4net.Appender.DebugAppender; the DebugAppender doesn't write to file.

This means that the log4net.config needs to change like so:

  <?xml version="1.0" encoding="utf-8" ?>
  <log4net>
	<appender name="FileAppender" type="log4net.Appender.FileAppender" >
	  <file value="C:\path\to\your\logfile.log" />
	  <layout type="log4net.Layout.PatternLayout">
		<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
	  </layout>
	</appender>
	<root>
	  <level value="ALL"/>
	  <appender-ref ref="FileAppender" />
	</root>
  </log4net>

And also, loggerFactory.AddLog4Net(); doesn't seem to automatically go find log4net.config (as it might be understood from the project's documentation). Instead, you must specify loggerFactory.AddLog4Net("log4net.config");.
