❔ Output to console if run from console - otherwise do not create console window?

I've got an Windows app that doesn't have a UI. I'd like to not have a console window opened when it's launched fron File Explorer, but if the user launches the app from a terminal (eg.
./myapp.exe
./myapp.exe
), then I'd want

Console.WriteLine

Console.WriteLine

calls (for debugging) to go to that terminal window. Is there some way to achieve this?

If I set the

OutputType

OutputType

Exe

Exe

, then it spawns a console window when launched from File Explorer. However, when run from a terminal window, the behavior is correct -

Console.WriteLine

Console.WriteLine

output goes to that existing terminal window.

If I set the

OutputType

OutputType

WinExe

WinExe

, the behavior is correct when launched from File Explorer - no console window is spawned. However, when run from a terminal window,

Console.WriteLine

Console.WriteLine

calls don't appear at all

The UserInteractive property reports false for a Windows process or a service like IIS that runs without a user interface. If this property is false, do not display modal dialogs or message boxes because there is no graphical user interface for the user to interact with.
