           Summary: System.Configuration: Application Scope settings are
                    saved in user.config

Source code to reproduce problem.

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; pl;
rv:1.9.0.5) Gecko/2008120121 Firefox/3.0.5

When using System.Configuration.ApplicationSettingsBase.Save() it should save
ONLY User Scope settings (only keys that are in userSettings). Unfortunately,
it saves also Application Scope settings in userSettings section which raises
key duplication exception.
Microsoft .Net stores in user.config only user scope settings.


Reproducible: Always

Steps to Reproduce:
1. Compile sources.
2. Run them - it should work without problems (you need to press any key to
continue program execution).
3. Run it again and there will be a exception.
Actual Results:  
Unhandled Exception: System.Configuration.ConfigurationErrorsException: Failed
to load value for 'AppSetting2'. ---> System.ArgumentException: Key duplication
when adding: AppSetting2

Expected Results:  
Application Scope settings should not be saved in user.config file. Program
should run properly.
