I guess the discussions arise as a result of people not being sure if they should consider WCF like Web Services which has a loose coupling (generated client proxies) or like Remoting which often has a tighter coupling between the interacting participants (shared dll).
Until now I've mainly been a fan of the loose coupling because of three things:
- It's the easiest and fastest just click the right buttons in your VS and you're set! (yes, I can be quite lazy at times but remember that lazy developers often are the best)
- There's no dependency of a specific version dll between the client and the server. If the Server gets an update that breaks the service-convention the client just has to regenerate it's proxy and you're set.
- I havn't seen a clean and pretty alternate solution before. Mostly it's been messy.
