Linq to Entities with WCF

Question

I have all my objects in a separate project in my edmx file, and I provide them to my client application using the WCF service.

This means that I do not need to provide my client application with a direct link to the project containing the edmx file. That would be bad because it associates an object with a query in the database.

But only the objects that my WCF service uses can be accessed from my client application. So, for example, because I have the following code in my service:

public MyClass GetMyClass()
{
     return new MyClass();
}

.. I can use MyClass access in my client application with something like:

myServiceInstance.MyClass cls = new  myServiceInstance.MyClass()

And if I have an object called MyClass2 in my edmx file that I want to use in my client application! How can I install it without providing my client with a direct link to the edmx file project or without using the useless method at my service level, which returns MyClass2

What are other people doing?

thanks a lot

Another way to handle this is to simply use svcutil (or "Add a service link ...", although svcutil works best for multiple service endpoints) to generate all the classes that the client will use instead of adding a link to the server project. Thus, the only classes your customer will ever see are those that are exposed by the service.
