What is the proper way of implementing a requirement like this to the watchOS with Xamarin? The user should have a simple one button solution (like the Amazon App on the watch) and upon the user request a custom web API should be called and the response displayed. This should work without the requirement of an unlocked phone or an open app (as a WCSession requires). I'm relativly new to the mobile development and this is my first step into the watch implementations. I can't find any good resource on the web on how to implement stuff like that. From the Xamarin examples and the Xamarin documentation I only found solutions for a open focused parent app - and that is not what I want.
