Uno Platform lets you write an application once in XAML and C#, and deploy it to any target platform.
Uno Platform applications run on Web (via WebAssembly), Windows, Linux, macOS, iOS, Android and Tizen. Check supported platform versions.
Yes - Uno Platform taps into the native UI frameworks on most supported platforms, so your final product is a native app. Read more about how Uno works.
Yes. Unless you specify otherwise, your application's UI renders exactly the same on all targeted platforms, to the pixel. Uno achieves this by taking low-level control of the native visual primitives on the targeted platform. Read more about how Uno works.
First, Uno Platform is available in production today to build single-codebase, pixel-perfect applications for Web, Desktop and Mobile. .NET MAUI is successor to Xamarin.Forms.
Second, Uno Platform can target additional platforms like Linux and the Web.
Third, Uno Platform aligns with WinUI, which uses a flavor of XAML most Windows developers are familiar with. It also allows you to tap in WinUI's rich styling engine to create pixel-perfect applications.
Finally, by extending the reach of WinUI across all supported platforms, it also allows you to leverage the rich 1st and 3rd party ecosystem and bring rich controls everywhere like DataGrid, TreeView, TabView, NavigationView and many others.
At the practical level, we suggest you try both and see which works the best for your skillset and scenario.
Uno Platform applications are cross-platform, running on the web as well as mobile and desktop, equally, from a single codebase. Blazor is a feature of ASP.NET for primarily building web applications.
Uno Platform applications are written in C# and XAML markup, whereas Blazor applications are written in 'Razor' syntax, a hybrid of HTML/CSS and C#.
Uno Platform and Blazor both make use of .NET's WebAssembly support to run natively in the browser.
Uno Platform and Flutter solve a similar problem - pixel-perfect applications on all target platforms. However, Uno Platform leverages decades of Microsoft's investment made into developer tooling .NET and C# programming language for developing applications.
No, there's no need to have an existing UWP or WinUI application, or have that specific skillset. The Uno Platform templates make it easy to create a new project in Visual Studio or from the command line for anyone familiar with C# and XAML.
Uno Platform is supported by a number of 3rd-party packages and libraries, including advanced controls from Microsoft Windows Community Toolkit, SyncFusion and Infragistics; graphics processing with SkiaSharp; presentation and navigation with Prism, ReactiveUI and MVVMCross; local database management with SQLite; and more. See the full list of supported 3rd-party libraries.
