That's a better explaination of the what's really going on :) I was under the impression that the binary distributions of log4net:
http://logging.apache.org/log4net/downloads.html are strongly named. FYI, if you download the source to log4net and try and build it you'll probably get a lot of build errors becuase the AssemblyInfo.cs file is looking for the .snk file. I comment out the following lines and I'm able to build: // [assembly: AssemblyDelaySign(false)] // [assembly: AssemblyKeyFile(@"..\..\..\log4net.snk")] Maybe you need to set the path to your generated log4net.snk file in order to build correctly. --- Ramaa Davanagere <[EMAIL PROTECTED]> wrote: > > Thank you for responding so quickly. > > After searching on internet for few days, I was able to get some help > with > COM + VB6 + log4net.
