Compiler Error Message:BC30002: Type 'MyClass' is not defined.

Compiler Error Message:BC30002: Type 'MyClass' is not defined.


I get The following Error Message: BC30002: Type 'MyClass' is not defined. Basically vb.net doesn't recognize my Class that i have made. i try to make the project as simple as possible to see if i can get around this problem but unfortunately i can't.
My project is made up of two simple files a web page called' DEFAULT.ASPX'  and a custom class called 'MyClass.vb'.
The aspx web page is made up of two components a grid and a button as shown underneath:

<asp:Button ID="Button1" runat="server" Text="Button"/>
<br/>
<br/>
<asp:DataGrid ID="Datagrid1" runat="server">
</asp:DataGrid>

The code behind of the default.aspx page has the following syntax:

Imports MyClass

Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim myDAL  As MyClass= New MyClass
        Datagrid1.DataSource = myDAL.GetAllCustomersDAL

        datagrid1.databind()
    End Sub
End Class

the  MyClass.vb file is located in the App_Data folder and  has the following syntax:

Imports Microsoft.VisualBasic
Imports System.Data
Imports System.Data.OleDb

Public Class MyClass
    Inherits System.Web.UI.Page
    Public DataBaseLocation As String = "C:\northwind.mdb"
    Public ConnString As String = "Provider=Microsoft.jet.oledb.4.0;Data Source=" + DataBaseLocation + ""

    Public Function GetAllCustomersDAL() As DataSet

        Dim Dataset1 As DataSet = New DataSet

        Dim SQLCommand As String
        Dim MyConnection As OleDbConnection = New OleDbConnection
        MyConnection.ConnectionString = ConnString
        SQLCommand = "SELECT * FROM customers"
        Dim dataAdapter1 As OleDbDataAdapter = New OleDbDataAdapter(SQLCommand, MyConnection)
        dataAdapter1.Fill(Dataset1, "customers")

        Return Dataset1

    End Function
End Class

I also opened the VS 2005 command prompt and navigated to the appropriate folder and entered the following command:
vbc /r:System.dll,system.web.dll,microsoft.visualbasic.dll /t:library /out:MyClass.dll MyClass.vb
This creates the MyClass.dll in the same directory where the MyClass.vb is located (App_Code).
After this step i add reference to the file by going to Add References, this adds the 'MyClass.dll' file to the 'BIN' directory of the project. I would like to point out that the web application runs fine when i am in the VB.NET environment i.e (http://localhost:1563//myProject/default.aspx) but I get the ERROR when i run the web application off the web server on my computer i.e (http://www.wiredbrain123.com/default.aspx).  Any help is appreciated, i am very desperate since i have tried everything i know and i have had this problem for the past month now with no solution.
thanks in advance,
 mike.
