Apple Watch OS 2 App in a Xamarin.forms App.

Hi,

 I have an iphone app published using xamarin.forms. I want to add a apple watch component ( using apple watch OS 2) to this.  I have the following questions :-

1) I could not find any document on how to do a hello world "Apple watch app" from xamarin.forms. I would really appreciate it if some one could share
some documentation.

2) Is the "apple watch OS 2" bindings available ?. If not any idea when will they be available.

Thanks,
Vasu
