在 EF Core 2.0.0 的Fluent Api中，没有任何方法需要 和具有可选，我有两个模型，人员和员工：

In Fluent Api at EF Core 2.0.0, there aren't any methods HasRequired and HasOptional, and i have tow Models, Person and Employee:

    public class Person
    {
        public int Id { get; set; }

        public int EmployeeId { get; set; }
        public virtual Employee Employee { get; set; } // Optional
    }

    public class Employee
    {
        public int Id { get; set; }

        public int PersonId { get; set; }
        public virtual Person Person {get; set; } // Required
    }

• 人员可能有员工：可选


• Employee 应该有个人： Required

• Person May to have Employee: Optional
• Employee Should have Person: Required
