readonly CLR properties (with no change notification support)

The WebBrowser control also has readonly CLR properties like CanGoBack. When we get the value of this property, the control looks at its navigation list and determines if there are any pages in the list and returns true if there are some navigable pages or false otherwise. Like any other web browser, our web browser needs to support backward navigation, if possible. For this purpose, we want to include a Back button on the interface. It seems like this would be easy to implement using the CanGoBack property. We could use this property in CanExecute of ICommand and use an instance of the command for this button. The only issue is that CanGoBack is readonly and does not support change notifications.

namespace UsingNonMVVMElements.Command
{
    using System;
    using System.Windows.Input;
    using System.Windows.Controls;
 
    class GoBackCommand : ICommand
    {
        public bool CanExecute(object parameter)
        {   ...
