Subject RE: Log4net not working as expected
Date Mon, 18 Dec 2006 14:58:27 GMT
I think I figured it out. I think there were 2 versions of the log4net DLL.
One in the GAC, and one in the same directory as the exe. The exe was using
one version while everything else was using another. I removed the dll from
the GAC made some changes and so far it seems to be working. Thanks to those
who responded.

Just a thought, since you are declaring the log member in the dll class as
static, it might be getting instantiated before the configuration has run.
Why not either make it property 

protected static log4net.ILog log

    return log4net.LogManager.GetLogger("EngineTasksFactory");

or just declare it locally in the method.

I have applications that have multiple assemblies all working as you would

I have an issue with log4net that I was sure was not an issue before. I have
a project which is made up of a few other projects. There's an exe and 4
other dlls. Logging from the exe works while logging from the dlls does not.
Like I say, I know this has worked before. I've read thru the documentation
and everything looks identical. Does anyone see what I might be doing wrong
here or know what the cause may be? Thanks.
