It can be done this way too using Properties Dictionary for storing data: Application.Current.Properties [“id”] = someClass.ID; for fetching data: if (Application.Current.Properties.ContainsKey(“id”)) { var id = Application.Current.Properties [“id”] as int; // do something with id } ref: https://developer.xamarin.com/guides/xamarin-forms/working-with/application-class/#Properties_Dictionary

You can try this Application.Current.MainPage.Width in my case this worked and i am able to find the device width in portable project itself.
You might try using BoxView // sl is a StackLayout sl.Children.Add(new BoxView() { Color = Color.Black, WidthRequest = 100, HeightRequest = 2 }); although in my test, the width request is not being followed. This may be a bug, or other settings might be interfering with it.
