I created the following C# class. How do I get these controls
into the Toolbox?

Thanks

using System;
using System.Drawing;
using System.Windows.Forms;
using System.Data;

namespace MCM.Projects.WinUI.Controls
{
	public class MyComboBox : System.Windows.Forms.ComboBox
	{
	}

	public class MyCommandButton : System.Windows.Forms.Button
	{
	}
	
	public class MyTextbox : System.Windows.Forms.TextBox
	{
	}
