It's not recommended to use WinForms on OSX or Linux.  (Or windows, for that matter, although, winforms on windows, is reliable and not going away anytime soon, so it's ok).  Winforms on mono is based on X11, which is no longer safe to assume is present or running on a mac or linux system.  Also winforms on X11 is very buggy.  So winforms on windows is stable and not going away...  Winforms on mono is both unstable, and going away.

On windows, it would be recommended to use WPF instead, 
and on OSX http://developer.xamarin.com/guides/mac/getting_started/hello,_mac/,
