When WPF come out, after a lot of “Pushing” Microsoft saw since and make it work on Windows XP – has anything like this been talked about for WinRT.

问题 My app stop working after switching to windows 8. I spend hours to debug the problem, found out IOCP behave differently between windows 8 and previous versions.

问题 This question already has answers here : How to call asynchronous method from synchronous method in C#? (14 answers) Closed 2 years ago . In a windows 8 application in C#/XAML, I sometimes want to call an awaitable method from a non asynchronous method.
