title: How could I know if I'm developing a c++/cx or c++/WinRT UWP application?
body: <p>I'm creating a c++ UWP application and I want this app to be c++/WinRT because I read that c++/cx is not supported anymore.<br>
  And this is how I created my application.<br>
  VS 2017 -> File -> New -> Project... -> Visual C++ -> Windows Universal -> Blank App (Universal Windows)<br><br>
  I'm sorry for this basic question but I couldn't find out if my app is a c++/WinRT or not.</p>
