Answer 1

Further to Appetere's comment on the second answer:

Also note that if you're debugging (and haven't disabled the vshost process), then when your application stops, yourexecutable.vshost.exe.config will be replaced with yourexecutable.exe.config again.

So once again, you may not see any changes you made afterwards! (If you stop at a breakpoint whilst debugging and look in the file after making your modification and calling refresh section, you'll see your changes).

This is very confusing if you are debugging a program which looks for a setting and, if not present, writes it. Even if you're forewarned against expecting the the setting to be there the second time you run the program, one might expect it to be there AFTER the first run of the program and BEFORE the second run ... alas!

It's nothing to worry about since it all just works when the application is deployed or started directly from bin as others have already stated...

But it's possible to fall into a 'trap' though if you're debugging your program and decide to use Application Settings for the first time, and to avoid hand-writing the XML you decide you'll start from code and get the program to write a setting... to get all that stuff, then maybe add several more.
