Hello, 

I am getting errors when the view containing the component loads, here is the view, please note I am setting the bindingContext programatically, and the instance of the ViewModel of the example you publish is exactly the same, but it is a property of the ContentPage, the others elements in the XAML view are accusing the context ok, and also, I does´nt get error regarding binding context property with the component, here is the XAML, and following the errors, then the .cs code of the view.
