RE: No output from l4n... OR Russell's an idiot...

[Nicko Cadell <ni...@neoworks.com>]

Russell,

Have you got a line of code like:

log4net.Config.XmlConfigurator.Configure();

Or an assembly attribute:

[assembly: log4net.Config.XmlConfigurator()]

If you don't have something like this then log4net won't start.
If you do, then could you post the output of the log4net internal debug?

Cheers,
Nicko
