This is the sample corresponding to the Commands tutorial.

Command is one of the important components of any MVVM (Model-View-ViewModel) application. MVVM architectures help with decoupling the components of an application to make the application easier to unit test, maintain and extend.

MVVM pattern can be implemented in NoesisGUI by using commands and a ViewModel class. The ViewModel is the class in charge of binding data to the XAML and implementing the delegate that will be invoked by the command.
