如何为实体框架复杂类型添加导航属性 [英] How do I add a navigation property for a Entity Framework Complex Type
问题描述
我使用VS2010 Beta 2，我有一个名为地址的复合类型，具有以下属性：
I'm using VS2010 Beta 2, I have a Complex Type called Address with the following properties:
- 街道
- 城市
- CountryId
我的模型中定义了一个国家/地区实体，但我似乎找不到从复合类型的 CountryId 属性添加引用（导航属性）的方法到国家/地区实体的 ID 属性。
I have a Country Entity defined in my Model, but I can't seem to find a way to add a reference (Navigation Property) from the CountryId property of my Complex Type to the Id property of my Country entity.
我是以错误的方式进行的这个我不能与设计师做的事情...
I'm I going about this the wrong way or is this something that I can't do with the designer??...
另一个选项是创建一个Address实体，但它听起来不正确对我来说
Another option I have is just creating an Address entity, but it just doesn't sound right to me.
推荐答案
Ok，
实体框架版本不支持复杂类型中的导航属性或外键。
It seems like the current version of the Entity Framework doesn't support a Navigation Property or foreign key within a Complex Type.
另一个明智的选择是创建一个单独的地址实体，它将具有所需的所有外键，然后在所有其他实体中创建导航属性。
The other sensible option is to create a separate Address Entity, which will have all of the foreign keys it needs, and then create Navigation Properties within all my other entities.
