Code snippets are a hidden gem in Visual Studio that most of us do not pay much attention to. Utilizing them correctly can increase productivity when we have a lot to code. In Visual Studio, code snippets are available for multiple programming languages e.g. C#, F#, XML, HTML, CSS, Python, etc. They are extremely useful when we have a bunch of boiler plate code for our properties, constructors, bindable properties, etc.
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.
In this post,
- Creating Code Snippets
- C# Examples
- XAML Examples
- Export Templates
In this post, we will learn how to create a card view with child views using custom layouts. Creating a custom card unifies the experience for the user, gives us more control on the design of the app and speeds up the cross-platform UI/UX workflows. It is easy to get a simple, yet flexible, card introduced in your app.
When using a container for dependency injection in your Xamarin.Forms app, you may find yourself trying to use a plugin or library that is
static that you want to register with your container. Having
statics in our code makes it hard to test and causes coupling. In this post, I will demonstrate using Prism.Forms how to inject a
static plugin or library that may or may not expose an abstraction.
If you are building a Xamarin.Forms app, it should be a no-brainer that you use MVVM pattern for your code base. It should also be a no-brainer that you give Prism.Forms a try. It makes development fast and code easy to maintain with its plethora of built-in services such for navigation, dependency injection, alerts, events, etc.
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.
