Answer 1

Just in case anyone needs here is solution in C++/WinRT. Say you have function ProcessFeedAsync() that would return IAsyncAction, just need following simple code:

winrt::init_apartment();

auto processOp{ ProcessFeedAsync() };
// do other work while the feed is being printed.
processOp.get(); // no more work to do; call get() so that we see the printout before the application exits.
