Hide C# Client Terminal Window

I need a small but crucial tweak to my C# client-server solution. Right now the client runs as a console application, so a terminal window flashes on screen each time it starts. I want that window completely hidden while keeping every existing feature, protocol call, and data exchange exactly as they are. The server side must remain untouched.

You are free to refactor the client into a silent background process, Windows Service, WinForms tray app, or any other approach you prefer, provided it:

• Preserves 100 % of the current client functionality and message flow.
• Requires no code changes on the server.
• Targets the same .NET version already in use (ask if you need the precise version).
• Starts silently and exits cleanly without leaving orphaned processes.

Deliverables: updated source code, a compiled executable ready for drop-in replacement, and a short change log noting what you altered. Once I can run the new client and confirm the terminal never appears while all functions still work, the job is done.
