    hopefully someone can help me with a clarification: I have some Windows 8.1 Universal apps all written in javascript. In order to reach the maximum audience (which means that I also want to ship to Windows 8.1 / WP 8.1 users after Win 10 launch) and to get most benefits of Win 10 UAP, what do I need to do?

    Do I need split the project into Win 8.1 and Win 10 and ship two versions of my app? Or can I ship a single version which runs on Win 8.1 / WP 8.1 but also on Win 10 with the new UAP benefits?

    @hish:No, you have to have 2 projects to both update existing 8.1 apps and make use of new UWP APIs, you can still reuse code through shared projects or portable class libraries though. This is gonna change after Windows 10 with the runtime checks of IsApiPresents etc, but for now, this is what we have to do.
