WinRT classes can usually be used on the desktop, but obviously since you're on the desktop and not on Metro, you can't use WinRT classes designed for interacting with Metro.

I am looking for the deployment from the app store, the follow me everywhere app settings and especially the siloed features that provides the user with assurance that the app will not hijack their PC in a virus like way.

Another way to put this is, I want to be able to write an app that when it is run on a windows phone looks like a windows phone app, on a tablet it looks like a metro app, on the desktop it looks like a desktop app.
