Paul,
Thanks for the response.
Each of the assemblies is configured via the following entries in the
AssemblyInfo.cs file:
[assembly: log4net.Config.Repository]
[assembly: log4net.Config.XmlConfigurator(ConfigFile =
"my-assembly-log4net.config")]
I've tried changing the "conversionPattern" to determine which appender
definition is being used. It is always using the application's appender
definition. All output is going to the output file defined there.
Any class that needs to log will have a static member like this:
private static readonly ILog DebugLog =
LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

How are you configuring? (programmatically, custom attribute, etc.) My guess
would be that the 'DebugAppender' is being added twice (once in two separate
repositories). You could use the same Repository for both assemblies. How are
you creating loggers in code?

Subject: Duplicate log entries with DLL/EXE combination
Hello,
We have a .NET executable and a DLL assembly that both use log4net. One of the
complications is that the DLL is also called from an unmanaged C++ application
and we want logging to work in that setting. Our current solution works, but I
get many duplicate log entries when I am running the .NET EXE with the .NET
DLL. The configurations are below. Any ideas for how to fix this? I have to
admit I don't really understand how it works now.
Thanks!
