C#.net run in background (NEED HELP)

Hello, I need help hiding a program in the background.

No, not the application it's self.

In Vb.net and Vb6 you could hide a program for example as notepad in the background with a shell code

Call Shell("notepad.exe",vbHide)

I've looked around on the Internet to see if there was an equivalent to hiding programs in background by calling them with a shell command.

I've tried everything I could think of with diagnostics. I've tried the CreateNoWindow method and that failed.

Please help.
