Is the BizObject class ever used? I notice some of the classes inherit from it but for what reason? It is an empty class in ThePhile finished project.

I am implementing ThePhile solution's framework in a project of mine and have a few common business logic functions that are used in all parts of the app. For instance, creating a NameValueCollection of state names from the db to generate dropdowns. I was thinking of creating a static method in the BizObject class which does this so I can use it easily in any page. So my question is... Is this what the BizObject class created for? Common global business logic?

Yes that's the idea. I'm sure that is expressed in the book.

It's up to you to figure what goes in there, just as it is your job to extend other base classes.

You'll find you don't need static/shared members in many cases.
