What are the pros and cons of writing C#/XAML vs. C++/XAML WinRT applications in Windows8? [closed]

Answer 1

The only advantage I can think of to use C++/XAML is if speed is important to your project. The advantage of C#/XAML is that is much more easier to code, especially if your project its in C# already.

By now there is no way to make an application that targets both the Metro and the desktop in Windows 8.

Hope this helps.
