Since the VideoLAN programmers do write Windows 8/RT/Phone apps using Linux based operating systems and GCC I was wondering, whether there is some progress in regard to how to program for Windows in a Linux environment, where Windows is used only for testing. How easy/ hard is it, to program a Windows RT (modern UI whatever)/ Windows Phone 8 application on Linux?
I imagine a situation, where you use tools such as Git, Emacs/ VIM, GCC, Mono etc. to do the job. How about submitting the app without Visual Studio?
I ask, because Microsoft open-sourced so much stuff now, using Linux based OS for development could (should?) become feasible while developing apps for their systems. Does anybody have some behind the scenes information on this? It is very hard to find some relevant info.
Note I edited this question to be more "straight to the point"
