## What it is
Xamarin.Forms is a cross-platform UI framework for building native iOS, Android, Windows, and macOS apps entirely in C#. Support officially ended on May 1, 2024, and it has been succeeded by .NET MAUI.

## Use cases
- build cross-platform mobile apps in C#
- share UI code across iOS and Android
- maintain a legacy Xamarin.Forms application
- migrate a Xamarin app to .NET MAUI
- create native UIs from a single C# codebase

## When to choose
- you are maintaining an existing Xamarin.Forms codebase
- you need to reference the framework's source for a migration to .NET MAUI

## When to avoid
- starting any new project - use .NET MAUI instead
- you need long-term support or security updates
- you want an actively developed cross-platform framework

## Facets
- artifact type: framework
- maturity: abandoned
- function: mobile-framework, ui-components
- domain: mobile-development, cross-platform, web-development
- platform: cross-platform, windows, dotnet
- tags: xamarin, csharp, native-apps, deprecated, net-maui-successor, android, ios, macos
