6. C# (Xamarin/.NET MAUI) – The Microsoft Ecosystem Solution

C# is used with Xamarin and .NET MAUI (Multi-platform App UI) to develop cross-platform mobile applications. MAUI, which replaces Xamarin.Forms, provides a unified framework for building Android, iOS, macOS, and Windows apps with a single codebase.

Key Features:

  • Unified framework with .NET MAUI

  • Strong IDE support (Visual Studio)

  • Full access to native APIs

  • Shared UI and business logic

  • Backed by Microsoft
