Save method is not working on New Setting Property

Question

I have a big project with many sub projects. For a specific sub project, I want to create user settings at run time.

I have initialized the settings file with one dummy Setting.

Why the settings are not getting saved into the Settings file ?

Some articles suggest to Set User-Scope ? I have no idea how to do that.

Thank you

 

try
{
    if (!string.IsNullOrEmpty(Properties.Settings.Default["mySetting"].ToString()))
    {
        //Do something here
    }
}
catch (Exception)
{
    SettingsProperty AProperty = new SettingsProperty("mySetting");

    AProperty.PropertyType = typeof(bool);
    AProperty.IsReadOnly = false;
    AProperty.DefaultValue = false;
    Properties.Settings.Default.Properties.Add(AProperty);
    Properties.Settings.Default.Save();
    Properties.Settings.Default.Reload();
}
