It is recommended you create a Task Scheduler task to run the program hidden on startup, automatically.
I use run-hidden, a simple executable that launches console programs hidden.
Although, you can run it directly through the terminal, with logs and a quit option.
To compile, use the .NET SDK's dotnet publish command, like:
dotnet publish -r win-x64
It will compile into a single executable as bin\Release\net8.0\win-x64\publish\WinHideDot.exe
