.NET Multi-platform App UI (.NET MAUI) is a cross-platform framework for creating native mobile and desktop apps with C# and XAML.
Using .NET MAUI, you can develop apps that can run on Android, iOS, macOS, and Windows from a single shared code-base.
.NET MAUI is for developers who want to:
- Write cross-platform apps in XAML and C#, from a single shared code-base in Visual Studio.
- Share UI layout and design across platforms.
- Share code, tests, and business logic across platforms.
.NET MAUI unifies Android, iOS, macOS, and Windows APIs into a single API that allows a write-once run-anywhere developer experience, while additionally providing deep access to every aspect of each native platform.
