Coming with Windows 10 are a lot of new features especially for XAML when creating a Universal Windows Platform application aka. UWP app. We can mention a few of them: new controls (as the RelativePanel, the SplitView and more); new tools for building responsive and adaptive UI (AdaptiveTrigger, Extension SDKs, etc.); and a new way to bind data to the UI, Compiled Binding.
You can find the original post explaining what Compiled Binding is and how it differs from classic DataBinding here : https://mcnextpost.com/2015/11/10/uwpxaml-compiled-binding-what-is-it/
