Web Service and Namespace

[munim]

Hello Guys!

I am new to .NET Platform and very new to Web services.

I have been developing a system which is a Windows Application (which is 40% complete, and I have been working on it for a month). All my classes, base classes, DAL, BLL etc are in a Class Library (. DLL file) that are managed in different namespaces for example:

using Example.DAL;
using Example.BLL;
using Example.Objects;
using Example.Objects.Bases;
using Example.Objects.Collections;
using Example.Objects.Interfaces;
 

and a lot...

Now my project manager saying that, this project has to be a smart client. Meaning that Windows Application will communicate with a web service. Before there were a reference added to my Windows Application.
But, now

Anyway, I have added an ASP.NET Web Service to my current solution, and added a reference to the Class Library that I am working on it.

On the other hand in my Windows Application, I added a Web Reference to the Web Service that I have created.

Now my problem is, I want to have access to all the namespaces and classes inside those namespaces through the Web Service.

For just testing, I also tried to write the following code in the Service.cs under App_Code Folder

public Example.Objects.Interfaces.IAccountsController GetAccountsController()
{
      return new Example.BLL.GetAccountsController();
}

But when I try to add the Web reference to my Windows Application I get the following error:
Cannot serialize interface Example.Objects.Interfaces.IAccountsController

Thanks in advance
