Only exposing interfaces from the server
-
I have an IIS-managed server object, exposed to clients using a service/wellknown web.config entry. But I don't want clients to have to know the type of the object (currently defined in a shared library) -- rather I want them to just query for the interfaces they require. This would theoretically allow me to change the underlying type on the server without code changes on the client. To achieve this I wanted to expose the type as System.Object, but does not seem to be allowed by the remoting system. Have I made a design mistake? If so, what should I be doing?

You'll have to expose the object as atleast its interface.
public IMyInterface GetIt() { return (IMyInterface)myObj; }where myObj is an object of any class that implements the IMyInterface interface -

You might be able to use internal on all other classes except your facades/interfaces. That should 'hide' those classes from all outside calls.
