UWP support

I'd like to add Oculus Rift rendering to a Universal Windows Platform app. There's a line in the release notes saying UWP isn't supported, but in this thread: https://forums.oculus.com/community/discussion/comment/427837/#Comment_427837 there's a comment that "The native Oculus PC SDK supports UWP, which is how Microsoft shipped Minecraft". So I'm not sure if what I'm attempting is possible or not.

When I call ovr_Initialize() from the UWP app, it fails with ovrError_ServiceConnection. Non-UWP test apps work fine. Has anyone succeeded in building a UWP app with the current SDK?
