TabModel Header on Sample Error

[icm-app]

I have an error in this code in sample

new TabModel { Header = new Tuple<View, object>(new HeaderView(), new { Title = "Tab 1" }), View = new Tuple<View, object>(new HelloView(), new { Message = "Tab Strip 1" }) }, Error Message : Severity Code Description Project File Line Suppression State Error CS0029 Cannot implicitly convert type 'System.Tuple<Xamarin.Forms.View, object>' to '(Xamarin.Forms.View View, object BindingContext)'

Please help.
