Ah yea invoke doesn't work on Windows. Not sure if it ever will. Let me ask @bitprophet if that is ever planned.

I'd rather not (poorly) reinvent the Wheel by writing our own invoke, and the alternatives are all either worse or don't work on Windows either afaik. Given that Linux and *nix os's are generally free and worst case scenario can be put on a VM at no cost inside a Windows machine I'm less worried about that. I don't want to sound like I'm discounting Windows though- Are you aware of anything like Invoke that works well that works on Windows?
