Create a new C# Windows Application Project called DotsDemo, and add the class MyView to the project and add the following code:

using System;
using System.Drawing;
using System.Windows.Forms;
using CsGL.OpenGL;
namespace DotsDemo
{
public class MyView : OpenGLControl
{
    public override void glDraw()
    {
        GL.glClear( GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT ); // Clear Screen And Depth Buffer
        GL.glBegin( GL.GL_POINTS );
        GL.glVertex2i( 100, 50 );
        GL.glVertex2i( 100, 130 );
        GL.glVertex2i( 150, 130 );
        GL.glEnd();
        GL.glFlush();
    }
    protected override void InitGLContext()
    {
        GL.glClearColor( 1.0f, 1.0f, 1.0f, 0.0f );
        GL.glColor3f( 0.0f, 0.0f, 0.0f );
        GL.glPointSize( 4.0f );
    }
    protected override void OnSizeChanged(EventArgs e)
    {
        base.OnSizeChanged(e);
        GL.glMatrixMode(GL.GL_PROJECTION);
        GL.glLoadIdentity();
        GL.gluOrtho2D( 0.0, Size.Width, 0.0, Size.Height );
    }
}
}

Modify the Form1 code so that is looks like the following:

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace DotsDemo
{
public class Form1 : System.Windows.Forms.Form
{
    MyView view = new MyView();
    private System.ComponentModel.Container components = null;
    public Form1()
    {
        InitializeComponent();
        view.Dock = DockStyle.Fill;
        Controls.Add( view );
    }
    protected override void Dispose( bool disposing )
    {
        if( disposing )
        {
            if (components != null)
            {
                components.Dispose();
            }
        }
        base.Dispose( disposing );
    }
    #region Windows Form Designer generated code
    [STAThread]
    static void Main()
    {
        Application.Run(new Form1());
    }
}
}

Using this technique you can add other controls and menus to your application using the Visual Studio form designer.
