在EF-core代码中建立一元关系的正确方式是什么？

public class EntityA
{
    public int Id { get; set; }
    public string Name { get; set; }

    public EntityB EntityB { get; set; } // 导航属性
}

public class EntityB
{
    public int Id { get; set; }
    public string Name { get; set; }

    public int EntityAId { get; set; } // 外键属性
    public EntityA EntityA { get; set; } // 导航属性
}

public class MyDbContext : DbContext
{
    public DbSet<EntityA> EntityAs { get; set; }
    public DbSet<EntityB> EntityBs { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<EntityA>()
            .HasOne(a => a.EntityB)
            .WithOne(b => b.EntityA)
            .HasForeignKey<EntityB>(b => b.EntityAId);
    }
}

using (var context = new MyDbContext())
{
    var entityA = new EntityA { Name = "EntityA" };
    var entityB = new EntityB { Name = "EntityB", EntityA = entityA };

    context.EntityAs.Add(entityA);
    context.EntityBs.Add(entityB);
    context.SaveChanges();
}
