## What it is
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

## Facets
- artifact type: library
- maturity: maintenance
- function: gui, ui-components, desktop-framework, sdk
- domain: desktop-applications, cross-platform, developer-tools
- platform: cross-platform, windows, dotnet, cpp
- tags: qt, qml, mvvm, native-rendering, net-core, mono, desktop-gui, linux, macos
