How can I confirm HttpClient is Native when I use Xamarin.Form?

As I know, when I create a Xamarin.Android project and use HttpClient with AndroidClientHandler, so AndroidClientHandler is the new handler that delegates to native Java/OS code instead of implementing everything in managed code. This is the recommended option.

But when I use Xamarin.Forms, How can I confirm HttpClient is Native or How can I use AndroidClientHandler?
