Implement webkit-based web browsing in the Windows Store app

Question

I want to embed a webkit-based web view in my Windows Store app. I tried using CefSharp and Awesomium, but unfortunately they use APIs that cannot use applications (e.g. System.ServiceModel.ServiceHost).

Are there any web libraries that are known to work in the Windows Store app?

Update: I tried calling CEF directly without a shell, but the CEF dll was unable to load, apparently because it calls APIs that are not available for Windows Store applications.
