How to debug a C# command-line program

You could add a call to Debugger.Launch to your startup code. Then you can compile, and start your app from the command line. You'll get a prompt asking you which debugger you want to attach (typically this will be a list of the different versions of Visual Studio you have installed), and away you go.

(But really, setting command-line parameters in Project properties > Debug tab is the better way to go most of the time. If that's not working for you, you should figure out why.)
