使用实体框架核心2在不同的受限上下文中存储对多个对象的引用

Question

I am trying design driven domain and am using entity framework core. From my understanding of design driven domain I should never reference objects in another bounded context, I can only reference their identifiers.

I have a class A in bounded context A which references many objects of type B in bounded context B like below were A should only store a reference to ids of the B objects.

public class A
{
    public int Id { get; private set; }
    public List<int> bIds { get; private set; }
    public int Name { get; private set; }
}

public class B
{
    public int Id { get; private set; }
    public int Name { get; private set; }
}

How do I describe that relationship configuration in the Fluent API? If I don't add any configuration then I get the error The property "'A.bIds' is of type 'List' which is not supported by current database provider. ".

Thanks

The important point is that these two are separate from each other Bounded Context(BC). If you want to use class B in Bounded Context(BC) A and in the aggregate where the class A is located, class B should be in this ValueObject`s role. And so if you want to communicate between two Bounded Context(BC), you can use Domain Events.
