Copying a file in VS.net

Sorry about the xpost. I made a wee mistake earlier.
======================================

I have a page in my web project "Webform.aspx" which has the general layout of all my pages and a blank code behind page
.
What I do is :

1) Copy the page and paste it into Visual Studio.
2) Rename it to......lets say "Webform1.aspx"
3) Change the code behing page so it reads
Public Class WebForm1

Whenever I try to run this new blank page I get the error :

Could not load type '_myProject.WebForm1'.

Can someone tell me how to do this. I am finding Visual Studio great for coding but at simple screen handling and general maintenance It is hopeless.

Thanks in Advance

In the HTML of the copied page have you should try changing the inherits call to the name of the new page.

VB Code:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1Copy.aspx.vb" Inherits="ProjectName.WebForm1Copy"%>

Also, rebuild your solution so the code behind is compiled and placed in your bin directory...
