Description
Describe the bug
I created a new WinUI C++ Packaged App and built it. this warning was emitted.
Should? be easy to switch to the conformant mode.
cl : command line warning D9047: option 'await' has been deprecated and will be removed in a future release.
Standard C++ coroutines are available by default in C++20 or later, or use '/await:strict' in earlier language modes.
