Kevin,

I'm having issues downloading the Powerpoint presentation.  The file I get is labeled "A".

Thanks, Chris. Better testing, right? The presentation file name had spaces in it so I replaced them with hyphens. You can download the slides now.

~Completely unrelated, but since dependency injection is frequently used to permit testing, you might find the Google Testing blog interesting reading...

The current entry (http://googletesting.blogspot.com/2008/10/to-new-or-not-to-new.html) discusses how DI isn't appropriate everywhere, e.g. you wouldn't want to use DI to provide `string` constructor parameters, or `int` parameters, etc., so it's useful to formally distinguish between types which should be used with dependency injection and those which shouldn't.

Very true, Jonathan. When you hear people say, "Every class is an service," it's OK to be a bit nervous about that. Those are your instincts speaking. We sort of implicitly know that classes represent contracts but that they aren't appropriately exposed as services using an IoC container or, worse still, an SOA framework like WCF. I like the "to new or not to new" phrase. That's cool. Thanks for the links.
