• Qt/.NET Toolkit: Proposes a toolkit for C++ and.NET interoperability, including a custom native host and a native-to-managed adapter module.
• Implementing C# Interfaces in C++: Demonstrates how C++ classes can implement C# interfaces, allowing for decoupling of interface and implementation in native interoperability.
• Extending Qt Classes in.NET: Shows how to extend Qt classes in.NET by combining a QObject-based wrapper with the implementation of a C# interface.
• Using QML in a WPF Application: Demonstrates how to use Qt/.NET to add a QML user interface to a WPF application, including binding QML properties to C# backend properties and embedding a QQuickView in a WPF window.

Key Information:

• Qt/.NET provides higher-level interoperability services such as object life-cycle management and event notification.
• Native implementation classes for C# interfaces must extend QDotNetInterface and provide implementations for all interface members.
• The QDotNetNativeInterface<T> is used to expose existing native types to.NET code.
• Qt/.NET makes it possible to use Qt API in.NET applications by combining a QObject-based wrapper with a C# interface.
• The on-going work on the Qt/.NET project includes the development of code-generation tools for native wrappers and interface implementations.
• A WindowsFormsHost element is used to embed a QQuickView in a WPF window.

Important Details:

• Example code is provided for implementing C# interfaces in C++, extending Qt classes in.NET, and using QML in a WPF application.
• The full source code of the demo application is available in the latest patch submitted to the Qt/.NET repository.
• Screenshots and a GIF show the WPF + QML demo running.
