带有代码的新页中未找到ASP.NET页错误

Question

I inherent a large ASP.NET web form application and try to add a new test.aspx page with code behind to a newly created folder - test.

Test.aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>

test.aspx.cs:

using System;

public partial class Test: System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write("This is a test");
    }
}

In my web.config file, I make the Test folder be accessible to anyone.

  <location path="Test">
    <system.web>
      <authorization>
        <allow users="*" />
      </authorization>
    </system.web>
  </location>

When I access it in my development machine using https://localhost/Test/Test.aspx . It works fine. But after I deployed to my server. I got error 404 - page can not be found when I do https://myserver/Test/Test.aspx .

The server is Windows 2008 R2. All other existing pages serve fine except for this new one.

Put another new page Test1.aspx without code behind in the same Test folder.

<script language="c#" runat="server">
public void Page_Load(object sender, EventArgs e)
{
  Response.Write("hello, world!");
}
</script>

https://myserver/Test/Test1.aspx . It returns me "hello, World!".

Put any image file in the same folder is accessible also. https://myserver/Test/test.gif .

What could be wrong for a simple new .aspx page with codebehind? I do not see anything in Windows event log or IIS log. How to debug this problem?

Please help

Moved from comment.

Replacing CodeFile with CodeBehind solves the problem.

Basically, we use CodeBehind if we need to compile in Visual Studio before deployment.
