Since update from Xamarin.Android 6.1.2 to 7.x F# project won't compile.
I am getting these errors:
Error FS0039: The value or constructor 'isNull' is not defined (FS0039)
Error FS0039: The value, constructor, namespace or type 'sortByDescending' is not defined (FS0039)
Error FS0039: The value, constructor, namespace or type 'tryHead' is not defined (FS0039)
Looks like F# core version in Xamarin.Android is downgraded and is too old.
The issue can be fixed by installing FSharp.Core via NuGet package.
