Code snippets can be a huge topic, but in this post, I will list some of the XAML and C# code snippets useful when developing Xamarin.Forms mobile applications.

I recently added a sample to Prism’s samples library on how to use cross-platform EventAggregator using Prism.Forms in a Xamarin.Forms app.
