In my UWP version app I have three file types that a user could click on and import into the app. I haven't been supporting OnFileActivated since users can import these file even in batch from the utilities menu. Now I want to launch the file with the app when clicked on. What I want to know is how do I do this using the debugger? Seems to me this could be done by supplying a command line argument though maybe not. Also there is little information from that point as how the MainPage receives the argument for the file clicked on. If I can debug I can figure that part out.
