Problem with Xamarin.Forms 4.4

The SqueakyApp sample stops working form Xamarin.iOS project after upgrading the nuget to use Xamarin.Forms (4.4)

/Users/sameer/temp/FSharp/SqueakyApp/SqueakyApp.iOS/MTOUCH: Error MT2101: Can't resolve the reference 'System.Void Xamarin.Forms.ItemsView::set_ItemSizingStrategy(Xamarin.Forms.ItemSizingStrategy)', referenced from the method 'System.Void Fabulous.XamarinForms.ViewBuilders::UpdateItemsView(Microsoft.FSharp.Core.FSharpValueOption1<Fabulous.ViewElement>,Fabulous.ViewElement,Xamarin.Forms.ItemsView)' in 'Xamarin.Forms.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null'.

For bigger updates (4.3 -> 4.4) we have to update FabulousXamarinForms so we can support the latest features.
This is currently in progress: #644 and the support should be there with the next release of Fabulous.

Closing it since #641 (with PR #644) already tracks XF 4.4 update.
