The Attachable property dock was not found in docklayout

[developer9969]

Hi This is a much needed functionality in xamarin forms.

Not really an issue because it still works but wondering if you have any idea how to make the message "The attachable property "Dock" was not found in type docklayout" not a static member.

when using the xampane:DockLayout.Dock="Right" etc...

thanks for your time
