I'm searching a way to use a JavaScript engine inside my Windows Phone application but I don't want to build a web application. Plus I have some trouble to find official support for those kinds of information.
I found this hack to inject Chakra in WP apps but apps won't pass Microsoft Windows Store certification requirements so this is not acceptable.
It's my first step to understanding WP apps, sorry if my question is trivial but I was wondering, is there any way to do this properly?
Unfortunately, no. The Chakra APIs are not approved for store apps at this time.
