MS has beautiful examples of Server/Client Socket, they work really well:

How could I adapt it to work with WinForms using a TextBox to display data?

How do I call methods StartListening(); and StartClient(); using a button from UI?

When data is received, how do I actively invoke an EventHandler, which would process the message based on a switch structure, and then perform different tasks based on the data received?

Thanks

What I have tried:

I've tried to implement the console code in a WinForms projects without much success.

Implementing sockets code in Winforms is exactly the same as in a Console app. The socket code should run in a background thread and pass information back to the Form code via event notifiers.

If the StartListening() method is in another class (public class AsynchronousSocketListener), how should I reference it from the UI thread?

Thanks I didn't see it yet, I'll take a look

Have a look here: Double Clicking a File in Explorer and Adding It to Your App while it's Running[^] - it uses Sockets to communicate between two instances of the same application and pass data from one to the other.
