C # Prevent console application launch as a Windows application from output?

I have a console application, to build as a Windows application, to run as a background process (I call it App 1).
When I launch another application, I send a message to App 1and then processes the message.
I want to prevent App 1ultil from exiting. I press a hot key.

Can you help me how to prevent App 1from automatic exit ? Thank you very much!
