This section contains documents that explain some more advanced cross-platform application features and concepts.
Version 5 of C# introduced two new keywords to express asynchronous operations: async and await. These keywords let you write simple code that utilizes the Task Parallel Library to execute long running operations (such as network access) in another thread and easily access the results on completion. The latest versions of Xamarin.iOS and Xamarin.Android support async and await - this document provides explanations and an example of using the new syntax with Xamarin.
The latest version of the C# language – version 6 – continues to evolve the language to have less boilerplate, improved clarity, and more consistency. Cleaner initialization syntax, the ability to use
catch/finally blocks, and the null-conditional
? operator are especially useful.
Building mobile apps with F# and Xamarin.
Visual Studio supports the creation of Portable Class Libraries using Visual Basic.NET which can then be incorporated into Xamarin applications. This article shows how to create a new Visual Basic PCL and then use it in a sample Xamarin.iOS, Xamarin.Android and Windows Phone application.
