In the previous post, we talked about the INotifyPropertyChanged, and I gave a small introduction about the MVVM architectural pattern, and how it will allow you to structure your code in a way that will make it easy to maintain, easy to scale and easy to reuse.

This post will be about the ICommand interface. If you have created Xamarin Forms applications before, this interface will help you replace all the event handlers you have in the code behind for button clicks (and other events) for code that you can now move over to your ViewModel.
