Entity Framework Foreign Key as Primary Key Code First

Question

I have two code first models, Foo and FooState where Foo has an optional FooState.

public class Foo
{
    [Key]
    public int FooId { get; set; }

    public Fo         


        

Answer 1

I thought I'd give this a shot and it worked nicely.

public class FooState
{
    [Required]
    [Key]
    [ForeignKey("Foo")]
    public int FooStateId { get; set; }

    [Required]
    public int State { get; set; }

    public Foo Foo { get; set; }
}
