WPF XAML App.config Transformations - Slow Cheeta

I was really tired of commenting and un-commenting out my app.config for my wpf application.  When  deploying I would forget to switch my database connection from dev to test or production.

I am now using Slow Cheeta to transform my app.config by build configuration.  Tying a build configuration to each one of my environments.  It is super easy and works great.
