Sending abstract class with DomainService WCF service to Silverlight

Question

I was using a simple WCF service with silverlight but I wanted to validate data with annotations and I didn't want to write a whole new layer in silverlight project. So I decided to switch to using a DomainService, created through generating code in the silverlight project.

Now comes the trouble. I have a parent class and about 10 derived classes. Through WCF, I was able to just use the base class. Now I am trying to use a DomainService with the base class decorated with the KnownType attribute. The problem is now those attributes get replicated in silverlight client and a compilation error is thrown. Anybody know how to use DomainService with inheritance? I want to deliver only the information from the base class.

我并没有完全理解您的问题所在，但这是一个很好的教程 ，说明如何在Silverlight中使用域服务，并且该示例包括所有实体的抽象基类，类似于我认为的做法。
