New API

  • Device.GetNamedSize (NamedSize size, Type targetType); Same as Device.GetnamedSize (NamedSize size, Element element) but doesn't require an instance.

Bug Fixes

Core

  • ListView/TableView respect WidthRequest/HeightRequest again (regression in 1.3.0-pre2)
  • No longer crash when trying to download/access the same UriImageSource on hundreds of images (System.IOException).
  • XAML now properly supports referencing other StaticResources from an Application subclass.
  • Fix issue where Grid sometimes measured out taller than it should, especially in ListView/StackLayout. Grid now prefers to expand in the direction of a "defined" constraint, which tends to match expected behavior when measuring. If both constraints are Infinite, previous behavior is retained.
  • BindableObject.SetValue will now properly perform loss-less conversions on base types. e.g. Calling slider.SetValue (Slider.ValueProperty, 6.0f) will now work correctly.
  • Fix issue where StackLayout in a Horizontal orientation would return an incorrect MinimumHeight in GetSizeRequest.

iOS

  • ImageCell no longer flashes old image on cell re-use.
  • Slider now updates bindings correctly due to conversion fix.

Android

  • Label.FontSize = 18 no longer accidentally gives a font size of 14 on any devices.
  • Fix another case where ScrollView content could flow outside of bounds (yay).
  • Fix crash in WebView when being removed from the visual tree.
  • Map no longer re-centers on Layout.

WinPhone

  • Back button now closes ActionSheets and Alerts before attempting Navigation.
  • Picker no longer shows a bunch of blank entries.
  • ListView selection now properly shows up.
  • ListView allows selection of items multiple times in a row if the user calls SelectedItem = null. This behavior matches other platforms correctly now.
  • Label now reports the correct minimum width to match other platforms.
