Subject RE: Error using RemotingAppender: can't find assembly log4net
Date Fri, 10 Dec 2004 14:34:03 GMT
I think I'm narrowing down my problem. I believe it can't load the log4net assembly because
the version used by the code generating the event may be different from the version used by
the Remoting code handling the event.

I'll post again when this is solved, just in case someone in the future gets the same error.

>Not sure what you mean. The client is not even aware that Remoting is being used since
it is all done in log4net, which is a black box to the client. The client works with other
appendes, just not the RemotingAppender.
>In the stack trace there is a message "Cannot find the assembly log4net". Not sure where
that's coming from or why it would come up.
