Hi,
You provide not enough information so that someone could help you finding out what's wrong. If you referenced the log4net DLL, configured the appenders properly and are writing some log messages but still nothing happens, it is always a good idea to enable log4net's internal logging to trace what's going on. All those steps should be covered in the FAQ section on the website.

It doesn't give me an error but I don't see the log file I made all the changes, imported all things but no success...
