QtSharp Mono/.NET bindings for Qt (gitlab)

https://gitlab.com/ddobrev/QtSharp
This project aims to create Mono/.NET libraries that wrap Qt thus enabling its usage through C#. It relies on the excellent CppSharp. It is a generator that expects the include and library directories of a Qt set-up and then generates and compiles the wrappers. While still in development, it should work with any Qt version when complete. There is no Qt included in the repository, users have to download and install Qt themselves. For now, Qt MinGW for Windows has been the only tested version. Qt for OS X and Linux are planned, Qt for VC++ has not been planned for now.

Language Bindings

https://wiki.qt.io/Language_Bindings
The Qt API is implemented in C++, and provides additional features for easier cross-platform development. QML – introduced with Qt Quick is a CSS and JavaScript-like declarative, language designed to describe the user interface of a program: both what it looks like, and how it behaves. As an alternative to using C++, bindings to Qt exist for several other languages, including Python, Ring, Go, Rust, PHP, and Java™. Officially, only the Python bindings are being maintained by the project, under the name of Qt for Python.

Porting from Qt 5 to Qt 6 using Clazy checks

https://www.qt.io/blog/porting-from-qt-5-to-qt-6-using-clazy-checks
If you are looking for some help to port from Qt 5 to Qt 6, look no further. Within the Clazy framework, we've implemented some checks and fixits dedicated to help porting your Qt-based project. Those checks can be run using Clazy as a compiler plugin, using clazy-standalone on a .json file or from within Qt Creator.
