I have a WCF service that send queries to a database using stored procedure. The WCF services are called with a WPF application where role-based authorization is implemented with IIdentity and IPrincipal. I want to use this role-based security to protect the WCF services, but I don't know how to proceed.
It's a bit of a mess in my head :) I read about Membership, RoleProvider... but don't really understand the difference and in what case to use these.
