we are designing a application with WPF/WCF... where we had lot of business leaked into the client code so inorder to avoid and make it clear we want to use the Domain Driven design . But where exactly my domain model will Sit .. in Server or client.
Note :To explain more about architecture we have WPF with MVVM we are binding the business entities and the WCF uses the Percall instances.. so it does the operation in the stateless Operation.
