This was a little cumbersome, but gave me an excellent opportunity to extend and play around with a concept I’ve been trying to perfect for a couple of years now. In a nutshell, what I wanted was the ability to just focus on implementing the specific functionality of a Web Service operation, yet reuse common validation, logging and exception handling. This required each web service to inherit from a common base class. Each request is a class which inherits from a base class also (containing properties which are required for every request).
