Behavior of INotifyPropertyChanged inside Config.NET

[coolfarmer]

Hi,

I'm trying to implement INotifyPropertyChanged, but I don't think I fully understand the concept when using it with Config.NET. What is it supposed to do? Is it supposed to update the UI when a configuration value changes?

I'm trying to implement it with Prism, but I'm sure I am missing something.

public interface IMyConfiguration : INotifyPropertyChanged
{
    string Name { get; set; }
}

public class MainWindowViewModel : BindableBase
{
    public ICommand TestClickButtonCommand { get; private set; }
    public IMyConfiguration config;

    private string title;

    public string Title {
        get => title;
        set => SetProperty(ref title, value);
    }

    public MainWindowViewModel()
    {
        TestClickButtonCommand = new DelegateCommand(TestClickBtn);
        Title = "Hi!";

        config = new ConfigurationBuilder<IMyConfiguration>()
           .UseJsonFile("AppSettingsTest.json")
           .Build();

        config.PropertyChanged += (sender, e) =>
        {
            Trace.WriteLine(e.PropertyName); // Log "Name" when button is clicked
        };
    }

    private void TestClickBtn()
    {
        Trace.WriteLine("Button clicked...");
        config.Name = "Hello World";
    }
}

Now that "Name" is logged at the line "config.PropertyChanged += ()", what should I do? Is there a way to automatically update my UI with the updated Title property?

I'm sure I'm missing something.

Thanks for help.
