Migrated Xamarin.Android project to AndroidX and had to update some packages. Now I am unable to build my project and getting following error messages:

Please advice how it can be fixed or how can I change the [Register] attribute and where it needs to be done. I cannot remove those packages, other packages depend on them.
After the migration , we'll need to make some manual namespace changes for scenarios the tool doesn't cover.
AndroidX replaces the Android support libraries , and so any references to Android support library types must be replaced with references to AndroidX types.
The following table shows the namespace changes
| Android support library namespace | AndroidX namespace |
|---|---|
| Android.Support.V4.App | AndroidX.Core.App |
| Android.Support.V4.Content | AndroidX.Core.Content |
| Android.Support.V4.App | AndroidX.Fragment.App |
| Android.Support.V7.App | AndroidX.AppCompat.App |
| Android.Support.V7.Widget | AndroidX.AppCompat.Widget |

Delete all the packages and re-add them in projects.
