Saving data for related Tables with foreign key - Entity Framework

Question

I am having trouble saving my entities to the database using EntityFramework. I have to tables, Player and Address. The Player table has a reference to the Address table by means of an AddressId foreign key relationship. So Player.AddressId points to Address.AddressId.

Now when calling the following code, I get an error that says: "A dependent property in a ReferentialConstraint is mapped to a storage-generated column"

public override int CreatePlayer(BizObjects.Player player)
{
    var entity = new EntityFramework.Player();

    entity.PlayerId = player.PlayerId;
    entity.FirstName = player.FirstName;
    entity.LastName = player.LastName;
    entity.Gender = player.Gender;
    entity.BirthDate = player.BirthDate;
    entity.DisplayAge = player.DisplayAge;
    entity.Level = player.Level;
    entity.PlayingHand = player.PlayingHand;
    entity.BackhandType = player.BackhandType;
    entity.PlayingStyle = player.PlayingStyle;
    entity.Description = player.Description;
    entity.UserId = player.UserId;
    entity.Address = new Address();
    entity.Address.AddressId = player.Address.AddressId;
    entity.Address.Line1 = player.Address.Line1;
    entity.Address.Line2 = player.Address.Line2;
    entity.Address.City = player.Address.City;
    entity.Address.State = player.Address.State;
    entity.Address.ZipCode = player.Address.ZipCode;

    _entities.AddToPlayer(entity);
    _entities.SaveChanges();

    return entity.PlayerId;
}

I am new to using EF. Any pointers is greatly appreciated.

Are you using EF 1.0?

Mapping entity properties to FK columns in EF 1.0 is not supported, you have to use a relationship and navigation properties.
