Qml.Net is a library that integrates Qt/QML with .NET (Framework, Core, and Mono), letting developers build cross-platform desktop applications with QML UIs driven by .NET types. Rendering and animations happen natively in Qt, with interop limited to data models exposed to the GUI.

Use cases

• build cross-platform desktop apps in C# with QML UIs
• use QML for MVVM data binding with .NET POCOs
• expose .NET properties and methods to a QML frontend
• emit signals from .NET that QML can listen to
• create native-rendering GUIs without PInvoke overhead
• reuse existing .NET business logic behind a Qt interface

When to choose

• you want a .NET backend with a modern declarative QML UI
• you need native rendering performance for animations and controls
• you target Windows, macOS, and Linux from one codebase
• you prefer Qt's mature control ecosystem over other .NET UI frameworks

When to avoid

• you want a pure .NET UI stack like WPF, Avalonia, or MAUI
• you need web-based UIs (HTML/Electron-style)
• you require active development and frequent updates - the project is in maintenance mode
• you only target mobile platforms
