FluentNhibernate .CheckReference失败

Question

public class WorldEntity
{
    public WorldEntity()
    {
        Scenes = new List<SceneEntity>();
    }
    public virtual int Id { get; set; }
    public virtual string Name { get; set; }
    public virtual string Picture { get; set; }
    public virtual IList<SceneEntity> Scenes { get; set; }

}

public class WorldMap : ClassMap<WorldEntity>
{
    public WorldMap()
    {
        Table("Worlds");
        Id(x => x.Id).GeneratedBy.Identity();
        Map(x => x.Name);
        Map(x => x.Picture);
        HasMany(x => x.Scenes).KeyColumn("Id");
    }
}

public class SceneEntity
    {
        public virtual int Id { get; protected set; }
        public virtual string Name { get; set; }
        public virtual string Image { get; set; }
        //public virtual int WorldId { get; set; }
        public virtual WorldEntity World { get; set; }
        public virtual short NoExits { get; set; }
        public virtual string AnimatedIntroPath { get; set; }
    }

    public class SceneMap: ClassMap<SceneEntity>
    {
        public SceneMap()
        {
            Table("Scenes");
            Id(x => x.Id).GeneratedBy.Identity();
            Map(x => x.Name);
            Map(x => x.Image);
            Map(x => x.NoExits);
            Map(x => x.AnimatedIntroPath);
            //Map(x => x.WorldId).Not.Nullable();
            References(wrd => wrd.World, "WorldId");
        }
    }

[Test]
     new PersistenceSpecification<SceneEntity>(Session)
            .CheckProperty(x => x.Name, "Scene Name")
            .CheckProperty(x => x.Image, "path to image")
            //.CheckProperty(x=>x.WorldId,aa.Id)
            .CheckReference(x => x.World,aa )
            .VerifyTheMappings();

运行测试后我收到此错误：

System.ApplicationException：对于属性'World'预期的相同元素，但得到了'TwitQuestNet.DataDefinitions.OrmConfig.Entities.WorldEntity'类型的不同元素。 提示：覆盖类型上的ToString（）以找出差异。    在FluentNHibernate.Testing.Values.Property 2.CheckValue(Object target) at System.Collections.Generic.List 1.ForEach（Action 1 action) at FluentNHibernate.Testing.PersistenceSpecification 1.VerifyTheMappings（T first）    在SceneTest.cs中的TwitQuestNet.Test.EntityMapTests.SceneTest.scene_map_succsess（）：第23行

我在这里做错了什么？因为我被困了将近一天:(

排序。我必须添加EqualityComparer（），测试将通过
