Cant find using CoreLocation; using MapKit; using Foundation; with MAUI .net 9

[schnemart]

Hi
Visual Studio Preview 2022 .net 9 MAUI
Cant find using CoreLocation; using MapKit; using Foundation; so CLLocation(), MKLocalSearchRequest and MKCoordinateRegion() etc does not work
Any Idea ?
Thank you Martin

see code below
