Почему я получаю отсутствующую конфигурацию карты типа или ошибку неподдерживаемого сопоставления в automapper?

Код:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using AutoMapper;

namespace TestAutomapper
{
  class Program
  {
    static void Main(string[] args)
    {

      var config = new MapperConfiguration(cfg => cfg.CreateMap<MyClassSource, MyClassDestination>());


      var mapper = config.CreateMapper();

      var source = new MyClassSource { DateTimeValue = null };

      var mapped = mapper.Map<MyClassSource, MyClassDestination>(source);
    }

  }

  public class MyClassSource
  {
    public object DateTimeValue { get; set; }
  }

  public class MyClassDestination
  {
    public DateTime? DateTimeValue { get; set; }
  }
}

Я думал, что эта ошибка устранена (https://github.com/AutoMapper/AutoMapper/issues/1095< /а>). Я использую Automapper 5.1.1.

cfg.CreateMap<object, DateTime?>().ConstructUsing(src => src.ToDate());
