Today we released the source code for the built-in ASP.NET 2.0 Membership, Role Management, Site Navigation, Session State, Profile, Web Events, and Web Part Personalization providers (basically all of the built-in providers that ship in the .NET 2.0 Framework Redist). You can download them here, and learn more about the ASP.NET 2.0 Provider Model from this site here.
