If you're talking about System.Windows.Forms.Application, it is always started with some form instance which becomes the application main form: Application.Run(Form) is called. You can create and show some other forms before calling Run. To do this, you can call System.Windows.Forms.Show or System.Windows.Forms.ShowDialog. This is pretty unusual unusual trick used to show some form before the main form on start-up. Nevertheless, the main form remains the one used as a parameter of the call to Application.Run(Form).

That said, you can call any other code before running Application. So, some part of application (non-capitalized) runs before running its Application (capitalized, System.Windows.Forms.Application), but the Application itself always start running with some form.

By the way, there is not such concept as "starting a class". Be accurate if you want to get some help. I still don't know what was your intention. I hope I gave you enough of related information. Your follow-up questions are welcome, but you need to explain your idea and your ultimate goal to get some further help.

You can start different Form depend on startup parameter etc.

C#

static void Main(string[] args)
{
 if (args.Length > 0 && args[0] == "/help")
 {
   Application.Run(new HelpForm());
 }
 else if (args.Length > 0 && args[0] == "/process")
 {
   ProcessFile f = new ProcessFile();
   f.Work();
   Application.Run(new AllDoneForm());
 }
 else
 {
   Application.Run(new MainForm());
 }
}

You just need to create a Windows Forms Application and in static void Main() you can use Application.Run(); without a From parameter, something like this

C#

static void Main()
       {
           Application.EnableVisualStyles();
           Application.SetCompatibleTextRenderingDefault(false);
           //Do Stuff Here
           Application.Run();
       }

It just seems to be a very non standard thing to do, and I personally can't think of a reason to do such a thing.
