If this is just a data object being shared by two apps, i'd define a base class with the shared information and extend it where needed. If operations are needed as well (or the data structure is different), I'd define an interface of the shared information and use two different implementations of that interface on the client and the service.
Also not sure why you want to use CustomData as a member, it makes more sense to extend it. On Thursday, October 17, 2013 1:40:07 PM UTC+3, Richard Zhao wrote: > > It's a special case.
