Can you mix HTML and XAML in a windows 8 Metro App?

Question

Is there anyway to mix HTML UI and XAML UI in a windows 8 Metro App?

Answer 1

I believe no, XAML and HTML/CSS are separate paths when it comes to presentation layer and you can't mix them (except for the 'dirty tricks' like WebView control in XAML, but it's no use for component reusability).

The Windows 8 architecture diagram might be useful to see how XAML/HTML/WinRT are they related. Apps in HTML/JS are rendered in Internet Explorer 10 Metro, just in another context (with extended APIs , different security rules etc), while XAML has different mechanisms. WinRT is deep below the presentation layer.
