Could not load inherited class for aspx page - asp.net

When I transfer my project to a server, I now get this error message. What does it mean and how do I fix it?
Server Error in '/HD' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'HD._Default'.
Source Error:
Line 1: <%# Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="HD._Default" %>
Line 2:
Line 3: <%# Register Assembly="FormControls" Namespace="FormControls" TagPrefix="FC" %>
Source File: /helpdeskform/HD/default.aspx Line: 1

The #Page directive included this attribute: Inherits="HD._Default".
This means that there is a class _Default in the HD namespace associated with this page.
The error means that this class cannot be found.
A fix depends on how the site is setup and deployed:
You can solve this by copying the class to the correct location
Use the Visual Studio deployment tool (right click the web project then Deploy)
I prefer using the deployment tool - you can deploy to a local folder to ensure all dependencies are there, then upload to a server if you are not comfortable or able to use the direct to server options.

ASP.NET MVC application in VS 2019 parser error in Global.asax.cs

Source Error:
Parser Error Message: Could not load type 'MyProject.MvcApplication'.
Line 1: <%# Application Codebehind="Global.asax.cs"
Inherits="MyProject.MvcApplication" Language="C#" %>
I have implemented all solution provided on below links and many more, but I'm not able to fix this issue. Is this related to the IDE? If so, I will open this app in something other than VS2019, then this issue would not occur.

To resolve the issue you could try below workaround:
1)Delete all files from the bin folder of the project. Right-click on the project and click clean and build.
2)Check your global.asax and global.asax.cs are correctly formated.
3)try to remove the site from the iis and recreate it by your self.
If the above way is not working then I suggested you to restart the application OR remove the temporary files in the computer by Run command temp and %temp% OR include the obj folder in to the project and rebuild and run.

Help me to find a proper solution. Thank you.
Check your Page directive and make sure it is inheriting the proper file.
<%# Page Language="VB" AutoEventWireup="false" CodeFile="Index.aspx.vb" Inherits="Reports_Index" %>
And check the partial class too.
Partial Class Reports_Index
This typically happens if you renamed the file.
Check for other/additional dependencies which you might've missed. The last time I had this error it was because I only deployed the files which were part of my current build, instead of all of the files in my ./bin/ folder. I looked in my (currently working) dev machine, in the project/bin/ folder and found a few additional files (which were not in my newest build). Once I added those to my server, problem-solved.

Could not load type 'umbraco.UmbracoDefault'

I have a remote server, in which I accidentally deleted a folder containing the entire website. No biggie, I thought, I just re-created it from the bin, and no damage was seemingly done.
But now the website will not work, due to the following error:
SERVER ERROR IN '/' APPLICATION
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'umbraco.UmbracoDefault'.

This is quite serious and I'm now completely out of ideas on what to do!
Recycling the App Pool resolved this for me.

Could not load type 'NavigateWebApp.Global'

Recently we have moved our project to web app and everything is good but suddenly I do not know when I am trying to debug my application its showing me the following error:
Server Error in '/' Application.
--------------------------------------------------------------------------------
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'NavigateWebApp.Global'.
Source Error:
Line 1: <%# Application Codebehind="Global.asax.cs" Inherits="NavigateWebApp.Global" Language="C#" %>

--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:2.0.50727.4971; ASP.NET Version:2.0.50727.4971
I am sure that there are no build errors.
This is probably caused by your 'NavigateWebApp.Global' class/namespace not being available in the location you've specified.
Check where you define this and ensure it's accessible to the Global.asax page.
The root of the problem is your Global.asax file is referencing a class which no longer exists (or at least at the location you have specified). Simple fix is to update the Inherits attribute with the fully qualified path to your Global.asax class name (which you will find in the Global.asax.cs file).

I just fixed the same problem just by copy pasting and recompiling solution.
