Make sure that the class defined in this code file matches the 'inherits' attribute

[christian.Blackburn]

Hi Gang,

On my development system I am not getting this error, but it does
happen when I upload it to my ISP. Can someone tell me why this is
happening? I don't have any user-defined controls which seems to be
the primary cause. My code is ASP 2.0/VB.

Thanks a bunch,
Christian Blackburn

Hi Gang,

I guess this is a pretty small group, because no-one answered my
question. However, I did figure it out and would very much like the
next guy to not suffer the same problems I did. I found so much
worthless unrelated Q+A on the web. It was an ASP.net 1.1 \bin\ folder
on the remote website that was causing the problems. Once I deleted
that folder the issue went away entirely.

Thanks,
Christian Blackburn

Could be Repeated referred Codebehind classes...

Thanks Christian,
We have come across this problem, we observed that same class file name is used in different codebehind classes/pages.

when we removed those conflicts, problem resolved.

hope it helps,

I had a master file, .master + .master.vb like this: (file name next first line inside)

Master 1 -----------------

wFormularios.master
<%@ Master Language="VB" CodeFile="wFormularios.master.vb" Inherits="formularios" %>

wFormularios.master.vb
Partial Class formularios
​

Needed another, similar master, so I made a copy and cjanged the external name; ended with 2 master files, like this.

Master 1 -----------------
wFormularioPesquisa.master
<%@ Master Language="VB" CodeFile="wFormularioPesquisa.master.vb" Inherits="formularios" %>

wFormularioPesquisa.master.vb
Partial Class formularios

Master 2 -----------------
wFormularioPesquisa.master
<%@ Master Language="VB" CodeFile="wFormularioPesquisa.master.vb" Inherits="formularios" %>

wFormularioPesquisa.master.vb
Partial Class formularios



Note the same partial class name. That resulted in the error.
Changed the class name by adding a "2" in the second master file, that solved the problem. Like this:

Master 2 -----------------
wFormularioPesquisa.master
<%@ Master Language="VB" CodeFile="wFormularioPesquisa.master.vb" Inherits="formularios2" %>

wFormularioPesquisa.master.vb
Partial Class formularios2

------

In my case, running a site on .Net 2.0.57***, I have a problem like this error message. The site has run well and uses two IIS web servers with load balancer. But since I updated on of the two .vb scripts in the folder, the same code started to give this error. I tried all the possible solutions (originally it has the right CodeFile and Inherits attribute values in Page declaration and they are unique). No change from CodeFile to CodeBehind helped. The same error appeared also in the other script in same folder. For example, I have /Developments/Details.aspx

<%@ Page Title="" Language="VB" MasterPageFile="~/Master.master" AutoEventWireup="true" CodeFile="Details.aspx.vb" Inherits="Developments_Details" %>


And the Details.aspx.vb code is:
Imports Smart
Imports System.Data
Imports System.Data.SqlClient

Partial Public Class Developments_Details
Inherits SmartPage

Where SmartPage is the a class in folder App_Code. Other pages that inherit it (and it inherits as base class System.Web.UI.Page) work fine. But after

change of the script, even returning the original one, I constantly get the same error "500: ....\developments\Details.aspx.vb(1): error ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (". What you would advise me to do?
