May be applicable for iPAD split view scenarios too (not sure)
I have a ScrollView inside a ContentPage that fills the ContentPage with a margin of 25 on all sides.
The ContentPage occupies 100% of main app window.
In my ContentPage I have subscribed to "SizeChanged" event which get notification correctly.
When I drag the right window edge, I expect the scrollview to honor the right margin.
How do I resize the ScrollView to match the new window size? ForceLayout on ScrollView/ContentPage does not work.
