I have a WP 8 app which is registered to open via a custom protocol (i.e. foo:// ) and this works when launched via Windows.System.Launcher.LaunchUriAsync.
However when Bing vision on WP 8 sees a QR code with foo://bar it doesn't launch my app and just displays "Message:foo:bar".
How can I get Bing Vision to launch my app when scanning the QR code?
