Ask HN: Now that VisualStudio is free and .NET is cross platform

Visual Studio heavily makes use of WPF thus seriously doubt it:

As for using Visual Studio on Windows and cross-compilation to Linux:

If you have not heard of the Mono project or http://monodevelop.com/ you should check it out. And MS recently said they're going to facilitate building Linux/OSX applications in Visual Studio.

I haven't seen anything indicating that you'll be able to run visual studio on other platforms. Just publish to run on those platforms. I'd love to be able to use VS to create windows apps from my MacBook.
