Hi there,

Your web.config file seems to be missing the connection strings needed by your app, and by the Membership provider. Where did they go? You can take a look at the download that comes with the book to see how they should look.

If that doesn't help, can you to provide more information such as the chapter, page and exercise number you're working on?

Cheers,

Imar
