Let's start our journey together to build beautiful native cross-platform apps with .NET, Xamarin, and Visual Studio! In this blog I am going to guide you through the entire process and describe everything that is in File -> New for Xamarin. If you are a more visual learner, I have a full video that you can watch:
Let's set some groundwork first by answering some frequent questions.
What is .NET?
What is Xamarin?
.NET has a series of frameworks that are built for it that enable unique scenarios for developer for specific platforms. For example, ASP.NET Core and Blazor are frameworks built for .NET for web development. WPF and UWP are frameworks built for .NET for desktop development. Xamarin is a framework and tooling that enables apps to be built for iOS, Android, and macOS. It also contains several libraries that enable cross-platform development across iOS, Android, macOS, and Windows including Xamarin.Forms for cross-platform user interface and Xamarin.Essentials for accessing native platform features cross-platform.
What programming languages can I use?
.NET supports several languages including C#, F#, and Visual Basic. You can use any of these programming languages to build apps with Xamarin, however I am a C# developer, and it is the primary language for app development. However, there are some fantastic frameworks for F# such as Fabulous for functional development.
XAML is another "language" that will be used to build user interface with Xamarin. XAML has been used for a long time to build Windows applications with WPF and UWP and has some great features including easy to read markup, Hot Reload technology, and advanced data binding to make UI development a breeze.
What tools can I use?
.NET enables developers to use a wide range of tools including command line, code editors such as Visual Studio Code, and full IDEs (Integrated Development Environment) with Visual Studio 2019 and Visual Studio 2019 for Mac. To develop mobile apps with Xamarin we will need to use either Visual Studio 2019 or Visual Studio 2019 for Mac as they have the full features to build apps.
So, let's get started building our first mobile apps with Xamarin!
