Scott Guthrie has announced the release of the source code for the built-in ASP.NET 2.0 providers. This is going to be a great resource for those people that need to implement their own providers to interface to existing systems. Its also going to be useful for those people that might want to tweak exiting providers to return their own MembershipUser derived classes which contain more information (something that I’ve seen a need to do in the past).

Detailed documentation is available at the Provider Toolkit site.
