Entity Framework Table Splitting: not in the same type hierarchy / do not have a valid one to one foreign key relationship

I'm using Entity Framework 6 with a Code-First approach, and I want two entities to be put in the same table. What am I doing wrong?...[Table("Review")] public class Review { public int Id { get; set; } public PictureInfo PictureInfo { get; set; }...
