.asax error

Hi,
Trying to run a web application which is called WebFormsDataBinding.

There is a page called ManuallyCoded.aspx
On top of this page, in it's html page there is this line as follows:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="ManuallyCoded.aspx.vb" Inherits="WebFormsDataBinding.ManuallyCoded"%>

But it gives an error as follows.
Parser Error Message: Could not load type 'WebApplication1.Global'.

Source Error:


Line 1: <%@ Application Codebehind="Global.asax.vb" Inherits="WebApplication1.Global" %>


I don't see why the error mentions WebApplication1 because the project is called WebFormsDataBinding

Any thoughts?
Thanks guys
