You can change the project settings to create a Console Application instead of a Windows Application (just hit Ctrl+Enter on the project in the Solution Window, and make that change).
That will compile the application as a Console Application, and you'll get a console. However, you'll still get your forms. If you want to not have Windows Forms, you'll need to remove the forms, and replace their functionality with command line arguments or configuration. You can then remove the Windows Forms references, and it'll be converted.
