A nice approach for a LOB WPF application

using System.Diagnostics;
using System.Windows.Input;

namespace Mainardi.ViewModels.CommandBase
{
    public abstract class CommandModel
    {
        private RoutedCommand _routedCommand;

        public CommandModel()
        {
            _routedCommand = new RoutedCommand();
        }

        public RoutedCommand Command
        {
            get { return _routedCommand; }
        }

        [DebuggerStepThrough]
        public virtual void CanExecute(object sender, CanExecuteRoutedEventArgs e)
        {
            e.CanExecute = true;
            e.Handled = true;
        }

        public abstract void Executed(object sender, ExecutedRoutedEventArgs e);
    }
}
