Did you actually add the Xamarin.Forms NuGet package to your workbook?

haaanz commented 5 years ago

yes, after creating new iOS Xamarin Form workbook there is Xamarin.Forms package added automatically. I even try to delete it and add it again. Both with same error.

haaanz commented 5 years ago

One more think, same workbook works for Android.
