IExpectNavigatingToCallback.OnNavigatingTo happens too late, the binding process has already been completed

[mauroservienti]

The WinRT binding process starts as soon as the DataContext is set, even if the component has not yet been added to the visual tree of the hosting window, in this case during the navigation what happens is that the bindings are evaluated before the NavigatingTo "event" of the navigation service. Should be interesting to be able to ask to the view resolver to resolve a view and a viewModel without glueing them and attach them in the navigation service after the NavigatingTo event.
