CodeFile inheritance

Good afternoon expert,

When I fali to get the aspx and the aspx.cs file line up I get these errors

Error 1 'ASP.security_aspx.GetTypeHashCode()': no suitable method found to override      c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\tk090509\efaaeacc\1191e53c\App_Web_ndujtr07.0.cs      1288      
Error 2      'ASP.security_aspx.ProcessRequest(System.Web.HttpContext)': no suitable method found to override      c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\tk090509\efaaeacc\1191e53c\App_Web_ndujtr07.0.cs      1293      
Error 3      'ASP.security_aspx' does not implement interface member 'System.Web.IHttpHandler.IsReusable'      c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\tk090509\efaaeacc\1191e53c\App_Web_ndujtr07.0.cs      208      

I  had this working in one web site and when I copied over to the new web site it quit working.
At the aspx file the first line is
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="TK090509._Default" %>

Then at aspx.cs file there is

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace TK090509
{
    public partial class _Default : System.Web.UI.Page

The name of the web site id TK090509

I am in VS 2005 do something in the back ground when it creates the files?
How can I get them lined up agin?

Thnaks.
