Question

The reason I am asking is that Visual Studio Express is missing this item when choosing “Add new Item”.

Because of that I would like to create it by hand but I do not know what code to add.

I would really appriciate if someone with professional or higher editions would paste the C# code that is generated when adding “Component Class”

SOLUTION

Use the code in the answer but to obtain visual part of the component, the user control has to be created and not just a regular class.

Answer 1

The code part

Component1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Diagnostics;
using System.Linq;
using System.Text;

namespace blabla
{
    public partial class Component1 : Component
    {
        public Component1()
        {
            InitializeComponent();
        }

        public Component1(IContainer container)
        {
            container.Add(this);

            InitializeComponent();
        }
    }
}

EDIT:

Component1.Designer.cs

namespace blabla
{
    partial class Component1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary> 
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Component Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            components = new System.ComponentModel.Container();
        }

        #endregion
    }
}

But there’s a visual part that you will miss…
