Pascal и С#

Тут такая проблема
К программе на Pascal (PascalABC.NET) подключаю модуль
Aboutbox in 'Aboutbox.cs', написанный на C#:

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

public class AboutBox : Form
{
public String Author = "nfex";
public String AppName = "about dialog";
public String Version = "1.0";
public AboutBox()
{
InitDialog();
}
private void InitDialog()
{
this.ClientSize = new Size(250, 140);
this.Text = "About";
this.FormBorderStyle = FormBorderStyle.FixedDialog;
this.ControlBox = false;
this.MinimizeBox = false;
this.MaximizeBox = false;
Button wndClose = new Button();
wndClose.Text = "OK";
wndClose.Location = new Point(90, 100);
wndClose.Size = new Size(72, 24);
wndClose.Click += new EventHandler(About_OK);
Label wndAuthorLabel = new Label();
wndAuthorLabel.Text = "Author:";
wndAuthorLabel.Location = new Point(5, 5);
wndAuthorLabel.Size = new Size(72, 24);
Label wndAuthor = new Label();
wndAuthor.Text = Author;
wndAuthor.Location = new Point(80, 5);
wndAuthor.Size = new Size(80, 24);
Label wndProdNameLabel = new Label();
wndProdNameLabel.Text = "Product:";
wndProdNameLabel.Location = new Point(5, 30);
wndProdNameLabel.Size = new Size(72, 24);
Label wndProdName = new Label();
wndProdName.Text = AppName;
wndProdName.Location = new Point(80, 30);
wndProdName.Size = new Size(120, 24);
Label wndVersionLabel = new Label();
wndVersionLabel.Text = "Version:";
wndVersionLabel.Location = new Point(5, 55);
wndVersionLabel.Size = new Size(72, 24);
Label wndVersion = new Label();
wndVersion.Text = Version;
wndVersion.Location = new Point(80, 55);
wndVersion.Size = new Size(72, 24);
this.Controls.AddRange(new Control[] {
wndClose,
wndAuthorLabel,
wndProdNameLabel,
wndVersionLabel,
wndAuthor,
wndProdName,
wndVersion
});
this.StartPosition = FormStartPosition.CenterParent;
this.ShowDialog();
}
private void About_OK(Object source, EventArgs e)
{
Control wndCtrl = ((Button)source).Parent;
((Form)wndCtrl).Close();
}
public static void Main()
{
new AboutBox();

}
}
