USING ASP.NET receiving error: Server Error in '/' Application

I am receiving Server Error in '/' Application when I run my .aspx page in
my local host. It is complaining that it cannot find the file that im
trying to inherit within my .aspx file. The line in my file looks like
this:
< Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb"
Inherits="ANDDI1.WebForm1" >
I have the .aspx file and the .aspx.vb file in the folder that im trying
to pull up. For some reason its complaining about the inherits file. My
project name is ANDDI1 but I don't see that file anywhere in my project. I
do not know what to include in my localhost folder so this doesn't occur.
Any ideas of what exactly im suppose to include in my localhost folder so
I can run my ASP.NET code? Right now I currently have WebForm1.aspx and
WebForm1.aspx.vb in my local host and my local host spits out the Server
error which is complaining about the inherits file.
Thanks in advance.
