Implementing .Net RIA Services with Silverlight3 using only existing code/classes? [closed]

As my latest questions have stated, i am in a process of researching on Silverlight 3 and its application as a suitable RIA solution to a pre-built project a client of ours wishes to webify. And my experience in .Net and silverlight is about 3 - 4 weeks.

I have now become aware of .Net RIA Services. I require to use an existing VB class; which was created as a quick wrapper class to emulate a small piece of the client's application code. This is used as a proof of concept. It contains one function which uses the client's DLL files to return a simple data type This class has already been used successfully with Flex/Weborb combination. I unfortunately do not have enough knowledge or experience in Silverlight/RIA Services to grasp what it is i have to do to get t开发者_高级运维he file working. All the examples I find online only specify the method where you use a database as dataSource etc.

Question Then: Could you please inform me how i would go about implementing RIA Services with Silverlight 3, using existing code/classes with no DB? Or could you point me in a direction for further research on the matter?

Thank you in advance.

I think a good place to start is Nikhil Kothari's Linq to Bing example. In that example he creates a DomainService (which is what you need to create) that makes calls to Bing. You could start there to figure out how to wrap the calls to your application code instead.
