Windows 8 Store Application Support for x:TypeArguments

Question

I\'d like to know the same thing as this: Silverlight 4 Support for x:TypeArguments ... but for Windows 8 Store Apps.

Why is x:TypeArguments available if it doesnt work?

Answer 1

Sadly it's not possible. I got a definitive answer from a Microsoft contact: "I can confirm that but x:TypeArguments use in Xaml is not a supported scenario Windows Store Apps."

Answer 2

I'm pretty sure the answer is the same as for Silverlight. WinRT Xaml is in many ways closer to Silverlight Xaml than it is to WPF, and they've made all sorts of strange decisions in what to include and what not to.
