Answer 1

Fairly simple, you will have to create platform specific implementations.

The Interface

public interface ISettingsHelper
{
    void OpenAppSettings();
}

iOS

public void OpenAppSettings()
{
    var url = new NSUrl($"app-settings:{app_bundle_id}");
    UIApplication.SharedApplication.OpenUrl(url);
}

Android

public void OpenAppSettings()
{
    var intent = new Intent(Android.Provider.Settings.ActionApplicationDetailsSettings);
    intent.AddFlags(ActivityFlags.NewTask);
    var uri = Android.Net.Uri.FromParts("package", package_name, null);
    intent.SetData(uri);
    Application.Context.StartActivity(intent);
}

From Xamarin.Forms project you could simple call OpenAppSettings();.

P.S.: Please keep in mind that this solution requires tweaking if you would like it to work on older devices.

Answer 2

Try Device.OpenUri(new Uri("app-settings:"));

If this doesn't work (I think it has a while ago), you probably have to do this in your platform specific parts and use e.g. the dependency service. For IOS then use UIApplication.SharedApplication.OpenUrl(new NSUrl("app-settings:"));

Edit: @EvZ's answer is the one with platform specific code and the abstraction, if you also need UWP you can call await Windows.System.Launcher.LaunchUriAsync(new Uri("ms-settings:privacy-location"));
