This book is written for ASP.Net 3.5 and I have created the site with ASP.Net 4.0. I am having difficulty with the Roles and Membership Mgmt section in that it returns an error. "cannont find the location" for the account authorization. Any ideals?

I have seen your post and I only have one question. What do you mean by "any ideals"?

you can not create an instance of IMessagingService, it was declared as an interface. Since EmailService inherits the IMessagingService interface the private member variable can hold an instance of an EmailService. Interfaces are a contract for other classes to fullfill through inheritance they do not contain concrete code and can't be instantiated.
