Example of Dynamic Proxy ViewModel in C#?

AModel.cs

using System;

namespace VMSandbox
{
    class AModel
    {
        public DateTime Date { get; set; } = DateTime.UtcNow;

        public int MyLifeForTheCodeDownloads { get; set; } = Int32.MaxValue;
    }
}

AModelViewModel.cs

namespace VMSandbox
{
    class AModelViewModel : ViewModelBase
    {
        private AModel _subject = new AModel();

        protected override object Subject
        {
            get
            {
                return _subject;
            }
        }

        public string Date
        {
            get { return _subject.Date.ToShortDateString(); }
        }        
    }
}

Program.cs

using System;

namespace VMSandbox
{
    class Program
    {
        static void Main(string[] args)
        {
            dynamic vm = new AModelViewModel();
            Console.WriteLine(vm.Date);
            Console.WriteLine(vm.MyLifeForTheCodeDownloads);
        }
    }
}

ViewModelBase.cs

using System.Dynamic;

namespace VMSandbox
{
    abstract class ViewModelBase : DynamicObject
    {
        abstract protected object Subject { get; }

        public override bool TryGetMember(GetMemberBinder binder, out object result)
        {
            result = null;
            var property = Subject.GetType().GetProperty(binder.Name);
            if (property == null)
                return false;

            result = property.GetValue(Subject).ToString();
            return true;
        }
    }
}
