Hi, I'm not entirely sure about your contribution rules/guide so I've created an issue here:
https://issues.apache.org/jira/browse/LOG4NET-435 This contains patches to add support for iOS and Android on the xamarin platform. Additionally it includes a patch to add an appender for the built-in Android Debug log. Please let me know if I have missed something or if there is anything you want me improve on the patchset. Cheers, Isaac P.S. I've subscribed to the development list after I created the JIRA issue, so I can't reply to that email sorry.
