How to establish communication between two simple console applications?

Question

.NET

Let me explain. I need two simple applications (the first is a menu, the second is a field for implementing selected operations), i.e. clicked in one application, the result is displayed in another.
Tell me, please, where is the best place to get material on this topic, which theoretical sections to focus on.

Answer 1

The simplest, if two simple console applications, then I would do this

The second application should be ready to receive command line parameters (args[]) and work with them
Work for 20 minutes

Answer 2
