Is there a way to write WinRT apps in Windows7 & VS2010?

Question

Is there a way to write WinRT apps in Windows7 & VS2010? Some SDK to download?

I'm particularly interested in networking stuff (Windows.Networking.Socktes)

Or do I need to use Windows 8 developer preview?

Answer 1

If there is a way to do it on Windows 7 I haven't seen it.

You can download VS 11 (with Fx 4.5) but it does not have any RT stuff.

So yes, the Win 8 preview seems to be the only route at this moment. Do get the largest download.
