I tried this solution (https://stackoverflow.com/a/3163050/766964) to use two versions of log4net (1.2.10.0 and 1.2.13.0), and it did get me past the File Not Found exception, but then nothing is actually logged.
UPDATE: I got it to log by specifying the full type information:
<!--<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>-->
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821" />
But does this work? Because shouldn't it use 1.2.13.0 section handler for that one? Is there a way to specify both handlers and two separate sections with the same name?
