EF 4.1 - Model Relationships

Question

I\'m trying to create a quick ASP.NET MVC 3 application using the RC version of EF 4.1. I have two models:

public class Race
{
    public int RaceId { get; s         


        

Answer 1

The problem here is 1:1 relation between Address and Race! You probably want to map it as 1:N so you need to modify address to:

public class Address
{
  public int AddressId { get; set; }
  public string Street { get; set; }
  public string StreetCont { get; set; }
  public string City { get; set; }
  public string State { get; set; }
  public string ZipCode { get; set; }

  public virtual ICollection Races { ... }
}

If you want to use 1:1 then you can't use AddressId in Race but AddressId in Address must be foreign key of Race because entity framework can achive 1:1 only be "sharing" primary key.
