Hi Guys, we are in the process of desigining a solution as : PL(Sliver Light) | SL(??wcf??) | BL(WWF) | DL(Entity Framework) during this process our thought is decouple the PL & SL ,so we thought of going with the XML based services Can u guys suggest what would be the better solution for desiging the SL(using WCF)which can do the transctions done through XML using WCF
