Jeff Prosise on the ASP.NET Provider Model

Jeff has written a series of articles for Microsoft on the Provider Model in ASP.NET. He links to them at the Wintellect Wintellog. They are posted at MSDN. This is the parent article. They are quite helpful. I looked so far at the membership provider. He provides a simple, somewhat crippled (readonly) sample that uses an XML file datastore.

[UPDATE]
Dino Esposito has an excellent (as usual) article in the December MSDN Magazine on the new provider for the ASP.NET Membership and Profile API.
