I’m trying to get the Coordinate of current location of my device using “GeoCoordinateWatcher” Class and feed it to a weather API query. But after installation of System.Device.Location.Portable package, I have following build error:

C:WorkGitHubWeatherPanelMainWindow.xaml.cs(38,36,38,56): error CS0234: The type or namespace name 'GeoCoordinateWatcher' does not exist in the namespace 'System.Device.Location' (are you missing an assembly reference?)

warning:

 warning NU1701: Package 'System.Device.Location.Portable 1.0.0' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8, .NETFramework,Version=v4.8.1' instead of the project target framework 'net6.0-windows10.0.19041'. This package may not be fully compatible with your project.

How to resolve this build error, or is there any other Nuget package to install to make GeoCoordinateWatcher code work? thanks.
