This document discusses updates and upcoming features for Xamarin developers. It summarizes that Xamarin allows building native mobile apps using C# with a shared codebase, and highlights improvements to the development experience including faster builds and debugging on devices. It also outlines new controls and features being added to Xamarin.Forms, and previews the future .NET MAUI framework for building cross-platform native UIs using a single codebase.
.NET North UG - What’s new & next for Xamarin developers
- 1. What’s New & Next for Xamarin Developers @JamesMontemagno
- 2. .NET C# C# Xamarin.Essentials C# Xamarin.Forms - UI Shared C# codebase • 100% native API access • High performance Shared C# Business Logic Delight Developers
- 5. Code faster Code further Code deeper Build & Deploy faster Startup faster Reduce app size Iterate faster
- 6. The New Xamarin Experience
- 8. Test changes made to your app, including multi-file code edits, resources, and references while using a much faster build and deploy cycle. With Hot Restart, debug your iOS app built with Xamarin.Forms on a device connected to your Windows machine allowing for a much faster inner development loop.
