This is the c# sample i'm talking about.. it's from this article:
Embedding a .NET WinForms Application in an Internet Browser Using WPF

Please help me.. i need to know the Visual Basic counterpart of this code

using System.Windows.Controls;
using System.Windows.Forms.Integration;
using Fibonacci;

namespace WPFHost
{
    /// <summary>
    /// Interaction logic for Page1.xaml
    /// </summary>
    public partial class Page1 : Page
    {
        private readonly MainForm mainForm = new MainForm();

        public Page1()
        {
            InitializeComponent();

            //Create a Windows Forms Host to host a form
            WindowsFormsHost windowsFormsHost = new WindowsFormsHost();
            
            stackPanel.Width = mainForm.Width;
            stackPanel.Height = mainForm.Height;
            windowsFormsHost.Width = mainForm.Width;
            windowsFormsHost.Height = mainForm.Height;
          
            mainForm.TopLevel = false;

            windowsFormsHost.Child = mainForm;

            stackPanel.Children.Add(windowsFormsHost);
        }
    }
}

What I have tried:

This is so far what i've worked for..

Imports System.Windows.Controls
Imports System.Windows.Forms.Integration
Imports webtry2

Namespace WPFHost


    Partial Public Class Page1
        Inherits Page

        'Dim mainForm As webtry2.Form1
        Private ReadOnly mainForm As webtry2.Form1 = New Form1

        Public Sub New()
            'InitializeComponent()
            Dim windowsFormsHost As WindowsFormsHost = New WindowsFormsHost()
            Dim stackPanel As StackPanel = New StackPanel
            stackPanel.Width = mainForm.Width
            stackPanel.Height = mainForm.Height
            windowsFormsHost.Width = mainForm.Width
            windowsFormsHost.Height = mainForm.Height
            mainForm.TopLevel = False
            windowsFormsHost.Child = mainForm
            stackPanel.Children.Add(windowsFormsHost)
        End Sub
    End Class

End Namespace

Im hoping for response. Thank you!
