https://developer.xamarin.com/samples/xamarin-forms/all/
The Microsoft Xamarin official website only has samples for how to use the UI.
In fact, most standard C# foundation can be used to Xamarin.Forms, just like the Socket.
But there is no samples for them.
Maybe there has some samples for use standard C# foundation in Xamarin.Forms, just I am not found.
Is there any official website for it?
