protobuf-net v2 r450继承

希望有人可以通过protobuf-net帮助我指出正确的方向。我能找到的所有示例代码似乎都表明我正在尝试的应该是可能的。

域名（我的最终域名将比这更复杂，但我甚至无法实现这一点）：

[ProtoContract]
public class GeographyData
{
    [ProtoMember(1)]
    public DateTime LastRefreshTime { get; set; }

    [ProtoMember(2, AsReference = true, IsRequired = true)]
    public GeographyItem Item { get; set; }
}

[ProtoContract]
[ProtoInclude(3, typeof(HotelData))]
public class GeographyItem
{
    [ProtoMember(1)]
    public Guid Id { get; set; }

    [ProtoMember(2)]
    public string Name { get; set; }
}

[ProtoContract]
public class HotelData : GeographyItem
{
}

测试

var geographyDataTest = new GeographyData();
geographyDataTest.LastRefreshTime = DateTime.Now;
geographyDataTest.Item = new HotelData
{
    Id = Guid.Empty,
    Name = "Test",
};

var test = ProtoBuf.Serializer.DeepClone(geographyDataTest);

例外：

无法将“Domain.Geography.GeographyItem”类型的对象强制转换为“Domain.Geography.HotelData”。

有人能给我一些指示吗？
