No logging output when using LogManager.GetCurrentClassLogger() about nlog HOT 4 CLOSED

When using LogManager.GetCurrentClassLogger() then NLog resolves the Logger-name by capturing StackTrace.

When using LogManager.GetCurrentClassLogger() together with minimal-API without namespace, then the Logger-name has no namespace. Trying to improve this with #5463 (Fallback to assembly-name as "namespace" prefix).

But your NLog.config-file says only loggers with the following names has target-output:

	<rules>
		<logger name="logdb" writeTo="log_database" />
		<logger name="logfile" writeTo="log_file" />
		<logger name="jsonFile" writeTo="json_File" />
		<logger name="logdbdevice" writeTo="log_databaseDevice" />
	</rules>

This means that LogManager.GetCurrentClassLogger() must return one of those Logger-names, else the Logger will have no output.

You can enable the NLog InternalLogger at internalLogLevel="Debug" and compare the output between NET6 and NET8. This might reveal the difference in behavior between NET6 / NET8.

I adjusted the rules section to

<logger name="*" writeTo="log_database,log_json,log_file" />

and LogManager.GetCurrentClassLogger() works fine ,
