I had similar issue and solved it by writing my own plugin by overwriting QQuickWindow. I've used the plugin instead of ApplicationWindow in qml. In the plugin class, you can easily set the windowIcon.

After that you can set the icon path in qml:

An upcoming version of QML.net will have app.SetWindowIcon(png path) method that makes this simpler.
