The process is similar, so we are going to assume you are refactoring to use the Model-View-Controller architecture and call everything a controller.

The binding engine in WPF-based applications is powerful and hides a lot of the plumbing that is necessary to connect a view and view model. In day-to-day development, this is advantageous, but when trying to demonstrate how to refactor for a controller ...
