Uno Platform
Uno Platform is an open-source UI framework that allows developers to build single-codebase applications that run natively on Windows, WebAssembly (Web), iOS, Android, macOS, and Linux. It uses C# and XAML, enabling developers to leverage existing .NET skills to create cross-platform applications with native performance and look-and-feel. The platform extends the Universal Windows Platform (UWP) API surface to other platforms, providing a consistent development experience.
Developers should learn Uno Platform when they need to build high-performance, native applications for multiple platforms (e.g., desktop, mobile, web) from a single C# and XAML codebase, reducing development time and maintenance costs. It is particularly useful for enterprises with existing .NET investments, as it allows reuse of UWP/WinUI code and skills, and for projects requiring WebAssembly support for web deployment without JavaScript. Use cases include business applications, line-of-business tools, and apps where consistent UI/UX across platforms is critical.
