This is hanging due to the way avalon.py works. It's primarily intended for
working at the interactive console. When Avalon.py gets started it hijacks the
console execution so that all execution occurs on another thread. This other
thread is the primary thread for the app's window and its constantly pumping
messages. This allows you to continue to work at the console while the app
remains responsive.
When you run this from a script that's not going to work because the script
isn't being entered at the console. The key thing you need to do is app =
Application() and then app.Run() at the bottom of your script. I copied the
necessary lines out of Avalon.py and ended up with:

Subject: Re: [IronPython] WPF 3D: Missing Viewport3D when importing
Sorry, please replace the previous script with the following one.
Running this script as standalone actually shows what I meant and
hangs. But I guess this is unrelated to the Viewport3D issue.
