custom classes as parameters in a web service

Hi!

I want to create some web service functions which take some custom classes as parameters. These classes are in a seperate assembly (myClasses.dll). When I create a new project to consume the web service, I notice that VS creates proxy classes not only for the web service classes but also for all custom classes used as parameters by the web service.

Since the client project has a direct reference to myClasses.dll I want to use classes from this dll but ofcourse I get a cast exception.

Is it possible for VS not to create proxy classes for the types used as parameters in the web service

Thanks,

Dimitris
