Hi experts,

I'm using Visual Studio 2010.
I create a blank website.
I'm using VB as the language.

After I created my blank website I went to this link:

I downloaded the Ajax Control Toolkit by clicking the big purple download button found at this link.

The file that is downloaded is called:

So I unzipped it.

So then I right clicked on my project and Added a reference and then selected AjaxControlToolkit.dll from the file that I just unzipped.

So after I added this reference my project looks like this:

my app directory
If you scroll down the page at this link, they are doing an example using the HtmlEditorExtender.

I'm trying to do this same example.

So then in my project in the page called Test1.aspx
this is what my code looks like:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Test1.aspx.vb" Inherits="Test1" %>
<%@ Register TagPrefix="asp" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
        <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
        runat="server" />
        <asp:HtmlEditorExtender ID="HtmlEditorExtender1"
        runat="server" />

But when I run this page I get this error:

error message on page run
Does anyone know why I'm getting this error and my Ajax HTMLTextEditor is not working?
Did I add the ajax toolkit wrong?

This is what my web.config looks like:

<?xml version="1.0"?>
