Answer 1

Try changing CodeBehind:

<%@ Page Language="C#"
AutoEventWireup="true"
**Codebehind**="AddToCart.aspx.cs"
Inherits="_AddToCart" Title="Untitled
Page" %>

To CodeFile:

<%@ Page Language="C#"
AutoEventWireup="true"
**CodeFile**="AddToCart.aspx.cs"
Inherits="_AddToCart" Title="Untitled
Page" %>

ASP .NET 1.1 used CodeBehind for compiling code in a separate file. ASP .NET 2.0 introduced the CodeFile syntax for compilation of partial classes.

See here for a more detailed explanation.

Answer 2

Specify the namespace of the Inherits property of Page directive

Look at codebehind of your page. It looks like:

namespace MyWebSite
{
     public partial class _AddToCart : System.Web.UI.Page 
     {
        //...
     }           
}

So you must change Page directive to:

<%@ Page Language="C#" AutoEventWireup="true" Codebehind="AddToCart.aspx.cs" Inherits="MyWebSite._AddToCart" Title="Untitled Page" %>
