portabilty with Windows and Linux

Hello everybody!

I'm a linux user, and I want to develop in this OS, the problem is that I can't run my applications under windows.

I use Debian Lenny with monodevelop, and it uses gtk-sharp 2.12.2. And that package doesn't exist for windows, so when I try to run my app, I get the error that says I can't run the program, because I don't have that package.

And I can't downgrade the version of gtk# on debian, because I have to uninstall the 2.12.2 to install 2.10.3 version. And if I try to uninstall gtk# 2.12.2 apt want's to uninstall monodevelop, gtk#, and gnome!!!

So, what can I do??? =S

thanks and sorry for my bad english =P
