Hi, I've been watching this project for quite a while and it looks like a great solution to cross platform GUIs for C#. One thing I'm particulary interested in is being able to create a generic QML documents for use with C++, Python (PySide2), and C# models.

One thing I've not been able to work out so far with qml.net is if there is support for defining a 'default' property in a C# model. In C++ this would be achieved using:
Q_CLASSINFO("DefaultProperty", "content")

Is there any way to do this currently in qml.net? I'd guess you could use an attribute to define a default property, but wasn't able to see anything within the sources. This seems like a similar open issue: https://github.com/qmlnet/qmlnet/issues/84

If it isn't currently possible, I'd be interested in giving it a go.

That isn't currently supported.

How would it look? Something like this?

[ClassInfo("Prop", "Value")]
public class NetClass
{
}

Yeah, that was the way I was thinking it could work. I'll look into pulling the code to see if I can work out how it would be implemented.
