Hi Volker, > How can I achieve that B also uses the log4net-config-file of A (for > definition of levels etc.)?
You could create a configuration file C that contains the definitions you need in A and B and reference C in A and B. I.e.: C / \ A B Literally said: A depends C B depends C What you should not do is create a cycle in the dependencies, i.e.: A / \ \ / B Literally said: A depends B B depends A Cheers
