WCF and WinFS

Thank you for the help.

I’d like use winFS as database, creating new custom schemas, then I’d like do services in WCF to save my objects in database (winFS). Have somebody any idea of the architecture of my application with wcf and winfs

if I create a custom schema "student" inherance of System.Storage.Item, winfs create form the schema a mapping class with my define attributes an the atributtes of System.Storage.Item, then if I’d like use a service of wcf that return a collection of students, how I convert the classes in datacontracts (datamember)
