Best Development Frameworks for C#

.NET Multi-platform App UI (.NET MAUI) is a framework for building modern, multi-platform, natively compiled iOS, Android, macOS, and Windows apps using C# and XAML in a single codebase. .NET MAUI uses the latest, modern technologies for building native apps on Android, iOS, macOS, and Windows abstracting them into one common framework built on .NET 6. Native apps look and feel like the operating system on which they belong by default and layouts are fully adapted to each device automatically with no additional code. Platform APIs are available directly from C# to access over 60 platform features from a single cross-platform API including access to things like isolated storage, sensors, geolocation, camera, and a whole lot more with no compromises.

The Windows UI Library (WinUI) is a native user experience (UX) framework for both Windows desktop and UWP applications. By incorporating the Fluent Design System into all experiences, controls, and styles, WinUI provides consistent, intuitive, and accessible experiences using the latest user interface (UI) patterns. With support for both desktop and UWP apps, you can build with WinUI from the ground up, or gradually migrate your existing MFC, WinForms, or WPF apps using familiar languages such as C++, C#, Visual Basic, and Javascript (via React Native for Windows).
