Windows will stop windows phone.
Then what's will happen for Xamarin ?
Its pretty much inadvertently happened already. The default templates no longer include WinRT and WindowsPhone by default and VS2017 doesn't support them all together.
Its probably important to note, Windows phone devices are 90% of the time still covered by the universal windows platform (UWP), as there are very few phones which are locked on 8.0 and 8.1 without options to update.
