Both let developers write a Qt Quick QML user interface backed by Rust or C# code. The Rust bridge maps QML objects to Rc> and shares foundations with CXX-Qt, so the two can coexist. A Visual Studio extension provides project templates and QML IntelliSense for C# projects, and a VS Code extension adds live QML Preview. Qt plans to move Bridges out of Technology Preview in the first quarter of 2027. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the Qt Bridge for Rust and how does it let me build a Qt Quick UI without C++? Qt Bridge for Rust lets you build a Qt Quick QML user interface backed by idiomatic Rust code, with no C++ headers, manual FFI, or prior Qt experience needed. It uses attribute macros like #[qobject], #[qproperty], #[qslot], and #[qsignal] to expose Rust structs to QML, maps QML objects to Rc>, and can coexist with CXX-Qt since they share the same foundations. _Developers weighing Rust GUI options can track how Qt Bridges for Rust matures by following coverage on daily.dev._ ### Can I add a Qt Quick UI to an existing C# application without rewriting it? Yes, Qt Bridge for C# is designed for .NET teams who want a modern, cross-platform UI without rewriting their application. Existing C# code stays as is while a Qt Quick frontend is added on top, exposing C# objects, properties, methods, events, and collections to QML. A Visual Studio extension adds project templates and automatic NuGet references, and a VS Code extension offers QML IntelliSense and live preview. _Teams deciding how to modernize a .NET app's UI can keep up with Qt Bridge updates on daily.dev._ ## Similar posts on daily.dev - [A Cross-Platform Rust UI Framework via Qt’s Bridging Technology](https://daily.dev/posts/a-cross-platform-rust-ui-framework-via-qt-s-bridging-technology-akolfd6zt) · Qt · 24 upvotes · 1 comments - [Qt Bridges: C\# Bridge 0.3.0 Beta Released\!](https://daily.dev/posts/qt-bridges-c-bridge-0-3-0-beta-released--zzdubhodx) · Qt · 11 upvotes · 1 comments - [Qt Bridges: Public Beta for the Rust Bridge Is Out\!](https://daily.dev/posts/qt-bridges-public-beta-for-the-rust-bridge-is-out--0hzeqlagm) · Qt · 5 upvotes · 0 comments - [Qt Bridge for Rust 0.3 Beta: CXX-Qt Compatibility and Soundness](https://daily.dev/posts/qt-bridge-for-rust-0-3-beta-cxx-qt-compatibility-and-soundness-xtsdk1mtu) · Qt · 4 upvotes · 0 comments --- Tags: [#rust](https://daily.dev/tags/rust), [#c#](https://daily.dev/tags/c#), [#qt](https://daily.dev/tags/qt), [#desktop-development](https://daily.dev/tags/desktop-development), [#qml](https://daily.dev/tags/qml) [View this post on daily.dev](https://daily.dev/posts/qt-bridges-technology-preview-qt-quick-uis-for-rust-and-c-developers-7zm1uevgc) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Qt Bridges Technology Preview: Qt Quick UIs for Rust and C# Developers","url":"https://daily.dev/posts/qt-bridges-technology-preview-qt-quick-uis-for-rust-and-c-developers-7zm1uevgc","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/qt-bridges-technology-preview-qt-quick-uis-for-rust-and-c-developers-7zm1uevgc"},"datePublished":"2026-10-27T09:01:04.835Z","dateModified":"2026-10-27T09:01:33.800Z","description":"Qt Bridge for Rust and Qt Bridge for C# have both reached Technology Preview status.
