What's your [technical] opinion regarding a communications layer in a multi-tier environment?
-
Hi guys, I'm about re-planning a larger LOB application (an older version, created as a 2-tier solution is already existing and running for a couple of years). The plan is to go from 2-tier to 3-tier. We are not about to reuse code, so in this regard I'm totally free! Ah yes, it's not a web-application (so no ASP.NET or Silverlight)... Merely Winforms/WPF... What I am thinking about is whether or not to not make all service directly accessible via a WCF-Service (per class) or going to implement a single Service for communication (call it "CommService" which can send and receive serialized objects) to handle data exchange. The application relies on several different entities (so I definetly have to implement a couple of WCF-Services when using the one-service-per-entity approach). What would be the best approach in your opinion?
