Next article about bugs in Xamarin will touch topic of Styles. Styles for all of controls not only Frame (and if you wondering why Frame you should check first two articles about Xamarin here and here).

    </Style>
  </ResourceDictionary>
</Application.Resources>

Issue can be observed when you bind BackgroundColor property of Frame control and something will trigger change of view model source property binded to background color. Continue reading “Xamarin Frame and disappearing Outline”
