.NET/C# Selectively starting with hidden main form

By Dag, on December 30th, 2016

A way to start a C# application with the main form hidden. NO flicker or conjuring of cheap tricks.

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.IO;
using System.Reflection;

namespace KeyGuard_Client
{
	static class Program
	{
		private static string exepath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
		
		[STAThread]
		static void Main()
		{
			Application.EnableVisualStyles();
			Application.SetCompatibleTextRenderingDefault(false);

			// Start minimized if we start from InstallDirectory.
			if (exepath != @"C:\InstallDir") {
				Form1 MainForm = new Form1();
				MainForm.WindowState = FormWindowState.Minimized;
				MainForm.ShowInTaskbar = false;	
				Application.Run(MainForm);
			} else {
				Application.Run(new Form1());
			}
		}
	}
}
