When I see the samples here https://developer.samsung.com/galaxy-watch/develop/samples/companion/hello-net

Wearable sample is with .net c# but android samples are in Java. Is there any good sample with c#?

my question is should we handle peer connection in Android project or it is possible to do it net.standard project as well if my android application is xamarin.forms based? 

Another way of asking:

this article describes as if we can implement it in shared project but samsung.sap isnt recognized if i install from nuget.org https://developer.samsung.com/galaxy-watch/develop/creating-your-first-app/net-companion/interact

And this article implement on Android project level

https://developer.samsung.com/galaxy-watch/develop/creating-your-first-app/net-companion/use-accessory

Which one should we follow?
