＃1368 。解决方法是将联接表映射到实体：

This is tracked by #1368. The workaround is to map the join table to an entity:

class Photo
{
    public int Id { get; set; }
    public ICollection<PersonPhoto> PersonPhotos{ get; set; }
}

class PersonPhoto
{
    public int PhotoId { get; set; }
    public Photo Photo { get; set; }

    public int PersonId { get; set; }
    public Person Person { get; set; }
}

class Person
{
    public int Id { get; set; }
    public ICollection<PersonPhoto> PersonPhotos{ get; set; }
}

请务必配置 PersonPhoto 和组合键：

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<PersonPhoto>().HasKey(x => new { x.PhotoId, x.PersonId });
}

要导航，请使用Select：

To navigate, use a Select:

// person.Photos
var photos = person.PersonPhotos.Select(c => c.Photo);
