Gene,
Thanks for the detailed error report!

There are some VB.NET examples in the download. Not as many as we would
like!
Have a look at: examples\net\1.0\Tutorials\ConsoleApp\vb\src
> QUESTION/PROBLEM:
This issue is related to the way in which you are asking log4net to load
it's configuration. From looking at the trace I assume that you are calling
DOMConfigurator.Configure() from within your application. This method of
configuration loads the configuration element from the config file using the
System.Configuration.ConfigurationSettings class. For this to work correctly
you need to specify the log4net section handler in the .config file like
this:
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
You might ask why the examples set the section handler to
System.Configuration.IgnoreSectionHandler?
If you call the DOMConfigurator.Configure(FileInfo) or
DOMConfigurator.ConfigureAndWatch() methods then the configuration is loaded
from the specified file whether or not it is a .net .config file. Therefore
the <section> handler is irrelevant.
If you use the DOMConfiguratorAttribute to configure logging this uses the
DOMConfigurator.Configure(FileInfo) methods to initialise logging, therefore
the section handler is not used here either.
Rather than configuring log4net programmatically try adding this assembly
level attribute to your application:
<Assembly:log4net.Config.DOMConfigurator()>
Cheers,
Nicko
