Can you mix up the language stack in windows 8 Metro?

Question

can you do HTML/C# , or HTML/C++ , or XAML/Javascript in Windows 8 Metro?

I know that i could have a HTML/JS that could include a WinRT .winMD "DLL" that happens to be C# or C++ and call it from the JS, but is there any other way?

Also i presume that i could make a WinMD Dll containing Javascript functions and call it from a XAML/C# or XAML/C++ but are these the only ways?

Answer 1

winmd is the only way to use c#/c++ in javascript. There is no support for javascript in c#/c++.
