Windows 8 Metro Style Application - Serial Port

Hi all, I'm trying to communicate an "Arduino" with a Windows 8 METRO style application, but as far as I have seen there is NO way to access the serial port from W8 Metro style app. This is what I found: http://blog.jerrynixon.com/2012/05/metro-answers-can-i-use-serial-port.html

I would like to ask if anyone has more information about this or whether there are any alternatives available to me.

Thank you in advance and best regards

or whether there are any alternatives available to me.

Dump Windows 8 and install a real OS.
