6. Hello Face: Windows 8.1 Apps and MVVM

Some people wants to see the world on fire, and most of them usually doesn’t care about simplicity. In example, for a simple app with a view and a button, they add an unnecessary infrastructure which really doesn’t add any value (my post about Scrum is not for beginners may be can explain this topic). So if we need to Upgrade my previous sample, to be used with an MVVM pattern, one solution can be these one.

First we need to create a Canvas Collection, and complete some face location information for each Canvas, like width and height. BTW, try to create a data binding for a Margin is almost impossible.

I added some transparency into the background color of the Canvas so it will be added in a cool way over each face, In the XAML file we add an ItemsControl and complete the Items Source property with our binding.

Done ¡!! We get a new Canvas in each detected face, similar to this one.
