           Summary: Saving custom user settings (from

Created an attachment (id=340485)
 --> (http://bugzilla.novell.com/attachment.cgi?id=340485)
sample app to reproduce the problem

Description of Problem:

When using a custom user config file derived from ApplicationsSettingsBase any
saving of the settings produces a user.config file which is invalid.

Attached is a sample app that demonstrates this issue and the output from the
app on both .net and mono.

A couple of observations:

1. The mono version of the .local user.config file is much larger and includes
the configSections
2. The AppConfig key/vals of AppName and AppID erroneously exist in the
userSettings section of the .local user.config file

Running the app more than once will cause app crashes as it finds duplicate
AppName:

Unhandled Exception: System.Configuration.ConfigurationErrorsException: Failed
to load value for 'AppName'. ---> System.ArgumentException: Key duplication
when adding: AppName
