Log4net just stopped working, there was a reason, but I don’t know how to fix it

Question

My log4net worked, and I’m not sure exactly when it stops working, but today, when I put the application on the production server, I didn’t notice that no logs were produced, that’s why does anyone know how to fix this

Answer 1

One of the reasons this happens is when the assembly order is changed and you have a link to the log before your log4net configuration.

log4net ? , , log4net GetLogger. log4net .

XmlConfigurator.ConfigureAndWatch(new FileInfo("log4net.config"));
log = LogManager.GetLogger(...));
