Entity framework code-first null foreign key

Question

I have a User < Country model. A user belongs to a country, but may not belong to any (null foreign key).

How do I set this up? When I t

Answer 1

I prefer this (below):

public class User
{
    public int Id { get; set; }
    public int? CountryId { get; set; }
    [ForeignKey("CountryId")]
    public virtual Country Country { get; set; }
}

Because EF was creating 2 foreign keys in the database table: CountryId, and CountryId1, but the code above fixed that.
