Can a XAMARIN.IOS app project use CoreBluetooth? I cannot find example/tutorial/guide

I need my Xamarin.IOS app to communicate with our embedded BLE device.

Cannot find example or guide for Xamarin.IOS using CoreBluetooth.

Tried BLE plugins but all have build or run errors. (WOJ, ARITCHIE, XABRE)

Can my Xamarin.IOS app truly use CoreBluetooth, or should I use plugin BLE?
