Ron,
The reason you're getting these compiler warnings is because you have your config file open when you build your project--if you close it, those errors will go away...it's actually Visual Studio's attempt at validating the config file--the section specified is valid--Visual Studio is just doing a bad job at validation--at any rate, you can simply ignore the warnings.
