Recently I had to add logging feature to the SharePoint project I’ve been developing. I had to use log4net. I followed my friend’s advice but for some reason it wouldn’t work in my case. I didn’t get any errors or exceptions. Simply nothing was logged to the file, which by the way would not be even created. All in all it looked like a problem with applying the configuration from log4net.config. Indeed, when I looked at the logger object if it’s been configured (log.Logger.Repository.Configured) and it said false.
It turned out the log4net.config was deployed in a wrong location. Apparently, it should be placed there: C:InetpubwwwrootwssVirtualDirectories80.
