how to implement a select API of berkley socket in Metro Style?

Question

I want to port a win32 project to Metro which is based on socket APIs, others is OK, but I don't know how to implement the select method?

Answer 1

winsock is not allowed (therefore select(...) also) in metro style applications.  You must use the Windows Runtime sockets.

Answer 2

I know win32 lib is not allowed, but I want to use windows runtime sockets to implement the function of win32 sockets, other win32 sockets APIs can easily be implemented by runtime sockets APIs, and I want to know how to use Windows Runtime APIs to implement the select API?

I'm looking for your guidance.
