Third Edit: I significantly altered my code towards the question's conclusion but left the original in case it was preferable........I'm having trouble figuring out how to use several one-to-one relationships in EF. I had already created a one-to-one link between two models, but when I tried to include a third model, things turned ugly. Second Edit...
The following is what I'm aiming to do:...public class class1
{
public int Id {get;set;}
[ForeignKey("Class2")]
public int Class2Id {get;set;}
public virtual Class2 Class2 {get;set;}
}
public class class2
{
public int Id { get; set;}
[Required]
public virtual int Class1Id {get;set;}
[Required]
[ForeignKey("Class...
Considering these classes:...public class A
{
public int Id {get; set;}
public int? BId {get; set;}
public B B {get; set;}
}
public class B
{
public int Id {get; set;}
public int? AId {get; set;}
public A A {get; set;}
}
...next, using Fluent API... modelBuilder.Entity<A>()
.HasOne(a => a.B)
...
