The ARView control belongs in the .NET Standard project since it will be a part of both applications. It's a standard Xamarin.Forms control that inherits directly from Xamarin.Forms.View. It will not load any Extensible Application Markup Language (XAML) (so it will simply be a single class), nor will it contain any functionality other than simply being defined, so we can add it to the main grid.

Go over to Visual Studio and go through the following three steps to create an ARView control:

1. In the WhackABox project, add a folder called Controls.

using Xamarin.Forms;
 
namespace WhackABox.Controls
{
    public class ARView : View
    {
    }
}
