App Config File not saving

Question

I am using the below code lifted from MSDN, but its not updating my app.config file. Am I missing something? Please help.

private void button1_Click(object sender, EventArgs e)
{
    Properties.Settings.Default.reliefPath = "reliefPath";
    Properties.Settings.Default.Save();
}

I am targeting .NET 2.0.

Answer 1

The app.config itself is never updated. Instead a copy is created in the isolated storage for your application. I believe it's under your profile's AppData\Roaming directory. That file is then loaded next time you run your application

Answer 2

The settings may be saved in your App Data folder, in a user.config file: Properties.Settings.Default.Save(); -> Where is that file
