Since the original answer is now obsolete, here is the new method:

using System.Windows.Input;

public partial class MyControlExample : ContentView
{
    // BindableProperty implementation
    public static readonly BindableProperty CommandProperty = 
        BindableProperty.Create(nameof(Command), typeof(ICommand), typeof(MyControlExample), null);

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    // Helper method for invoking commands safely
    public static void Execute(ICommand command)
    {
        if (command == null) return;
        if (command.CanExecute(null))
        {
            command.Execute(null);
        }
    }

    public MyControlExample()
    {
        InitializeComponent();
    }

    // this is the command that gets bound by the control in the view
    // (ie. a Button, TapRecognizer, or MR.Gestures)
    public Command OnTap => new Command(() => Execute(Command));
}
