Trouble Loading Code Behind Type

Hello,

I'm a new VS.NET user having the following issue.

I've created a new ASP.NET WEb Forms app and have been doing some basic
things with no real problems.

I have decided that the next thing in the development will be a secured area
of the app.

I have determined the Forms Authentication is the way I am going.

I have created a basic login form and modified the Web.config file in my
app's main virtual directory (where all of my files have hitherto resided).
I got this all working, no problem. When a page was requested, the user was
redirected to the login form as expected and when authenticated the
originally requested page was properly display.

Here is where the problem comes up. The site will be a mix of public and
"auth-required" pages. So this basically means that I do not want the
"main" virtual directory of the app secured.

Here is what I did.

First, I disabled the authentication requirement on the main virtual
directory.

Then I created a new virtual directory (under the main app's virtual
directory) and called it "Secure".

I moved the Login.aspx (my custom login form) into the Secure virutal
directory and created an additional blank page in there as well.

I put a new copy of Web.config in the Secure virtual directory and
configured it up for Forms based authentication.

Here is what I expect to happen.

When a page in the app's main virtual directory is requested it loads
for anyone (this works fine).

When a page is initially requested in the Secure virtual directory the
user should be redirected to the Login form (the redirection occurs as
expected)

Here is the problem: The Login.aspx page pops a run time error
complaining that the code behind type cannot be loaded.
Parser Error Message: Could not load type 'RPG.Login'.
The application is named "RPG"
Here is the @dotnet.itags.org.Page
<%@dotnet.itags.org. Page Language="vb" AutoEventWireup="false"
Codebehind="Login.aspx.vb" Inherits="RPG.Login"%
Note: This was not erroring out when page in question was in the app's main
virtual directory. It only occurs for pages (I have tested a "Hello World"
page in the same virtual directory with the same error.

This seems to be some sort of pathing issue, but with the .aspx file and the
.aspx.vb file in the same folder, I don't get the problem. I've tried
changing the reference in the "Inherits" attribute to things like
RPG.Secure.Login but I'm too new to the environment to understand the
Namespace.Class reference and how it is effected by the location of the
files in question.

TIADo you have a file called "RPG.dll" in the /bin folder in the web application root?
Yes. RPG/bin/RPG.dll exists.
