Currently you could run coreclr apps on Linux / Mac, you just can't pull the dependencies without mono, since CoreCLR for Mac / Linux still misses NuGet mechanisms
It may actually work on *nix, I just haven't tried it. The powershell script won't run and you'll have to do it manually, but it's just a ten line script or so.
Did you read our comment thread? I'm complaining that there isn't parity for the dotNet/Roslyn development. You reply that you're working currently on CoreCLR as a response to this, so I asked for where I can do this. You state, it's not at parity. I jokingly refer you back to my original comment, and you glibly try to insult me? What the hell dude?
