I have an application that works with Mixed Reality Headsets using WebVR 1.1 in Edge. I've ported that application into the Windows Store as a UWP application (essentially just the HTML/CSS/JS web content and a manifest, bundled into an APPX). Since the application is displayed using an embedded Edge browser, I was hoping that the Mixed Reality Headset might "just work." Unfortunately, it "just doesn't." The code sees WebVR API support, so my app puts up the goggles icon, but when I click it, nothing happens.
You can find the web version of this application at m.kaon.com/c/gc (since WebVR cannot change pages right now, and Mixed Reality Controllers aren't available yet, there's not a ton you can do with it yet; I recommend going into a 3D model, then clicking the goggles).
The same application can be found if you search for "GP PRO" on the Windows Store.
Is it worth my trouble to try to make this work, or is WebVR in a UWP Web App not really supported yet?
