I did that the other day, on beta8 or whatever. In that case, I could run a console app. Then I tried the Yeoman setup [1] for a simple website without auth. It failed to run.
Today, I uninstalled mono, previous dmx stuff, and ran the package linked in this story. Same result. Yeoman website failed.
It's failing to resolve the fx dependencies.
Also, it's difficult for me to understand if I need mono or not. I have it.
