title: Binding BarBackgroundColorProperty in Xamarin.Forms
body: <p>I'm relatively new to C# and the idea of data binding (that is, I'm not sure I completely understand it). I am looking to try to bind NavigationPage's BarBackgroundColorProperty for sake of being able to change my root page's bar background color multiple times for a theme feature I'm trying to implement. I've searched around for examples of binding this property and haven't had much luck. Could someone point me in the right direction? If anything is unclear, please let me know. Thanks guys!</p>
