当KnownType类在另一个项目中时，接收从WCF服务继承的类吗？

Question

I need receive a class inherited through WCF Service.

<DataContract()>
<KnownType(GetType(A))>
Public class Base
...
End Class

<DataContract()>
Public Class A
Inherits Base
...
End Class

The problem is that A class is in my business logic project and it references Base class that is in another project (util project). Then i can't do:

<KnownType(GetType(A))>

In Base class because i would need add a reference to business logic project from util project to know class A, but its throws cyclic reference error.

And well, WCF project references business logic project to send data.

好吧，最后我在业务逻辑项目中创建了一个名为“ pack”的类，并扩展了util项目中的Base，然后“ pack class”可以知道业务逻辑项目中的类，而“ A class”则扩展了“ pack class”，并且“包装类”是通过WCF服务发送的包装类。
