How do you do a command line build of a Xamarin.iOS project?

Question

I've got a working Xamarin.iOS project, using 4.1.9 (on the Alpha channel).

How do I build it from the command line (not from inside Xamarin Studio)? I tried mdtool and that produced:

Answer 1

Try using /Applications/Xamarin\ Studio.app/Contents/MacOS/mdtool or /Applications/MonoDevelop.app/Contents/MacOS/mdtool.

In other words not directly mono on mdtool.exe (which might miss configuration...).
