But it's one thing to talk about them, another to design them, and yet another to implement them. What Patterns can you use to design the external interfaces of a Web Service, and keep it service-oriented? How do you avoid the tight-coupling in functionality and time of traditional RPC, and instead achieve the loose-coupling of functionality and response found in a document-centric web service? What Patterns can be used to design the internals of a web service, and keep it light-weight and flexible? In this session we'll analyze a service-oriented document-distribution system to learn what types of patterns you can use and how to take advantage of them. And you'll see a complete implementation in C#, which will demonstrate the versatility of the .NET Framework and the tools used to implement the service.
