Почему возникает исключение инициализатора типа Moq.Proxy.CastleProxyFactory при использовании NET40-NoCastle?

Итак, я скопировал пример кода с домашней страницы Moq практически дословно и получаю исключение прокси замка.

Вот мой код (как консольное приложение для более простой пример)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Moq;

namespace MoqTestConsole
{
    public interface ILoveThisFramework
    {
        bool DownloadExists(string s);
    }

    class Program
    {
        static void Main(string[] args)
        {
            Mock mock = new Mock();

            // WOW! No record/replay weirdness?! :)
            mock.Setup(framework => framework.DownloadExists("2.0.0.0")).Returns(true);

            // Hand mock.Object as a collaborator and exercise it, 
            // like calling methods on it...
            ILoveThisFramework lovable = mock.Object;
            bool download = lovable.DownloadExists("2.0.0.0");

            // Verify that the given method was indeed called with the expected value
            mock.Verify(framework => framework.DownloadExists("2.0.0.0"));
        }
    }
}

Все компилируется хорошо, но когда он вызывает mock.Object Выдается следующее исключение.

Таким образом, похоже, что компонент Castle Proxy отсутствует, но я имею в виду двоичный файл из каталога NET40-NoCastle .

Последняя версия Moq (Moq.4.0.10827)

И я новичок в Moq, поэтому я могу делать что-то чрезвычайно сложное.
