I am getting the following error on one of our production servers. Not sure why it is working on the DEV server?

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 'TestMvcApplication.MvcApplication'.

Source Error:

Line 1: <%@ Application Codebehind="Global.asax.cs" Inherits="TestMvcApplication.MvcApplication" Language="C#" %>

Source File: /global.asax Line: 1

Not sure if anybody came across this error before and how it was solved, but I have reached the end. Any help would be appreciated.

I also need to mention that this is the published code, so all is compiled. Can there be something wrong with my compiler settings?

I've had this a couple of times. It's especially frustrating as it's right off the bat, and the error message holds no clue as to what might be the issue.

To fix this, right click your project title, in this case "TestMvcApplication" and click build.

This forces the code to compile before you run it. Don't ask me why, but this has been the solution 100% of the time for me.

I had the same problem: mine was because the web project had a platform target of x86. I was running on a 64-bit machine; other projects in the solution were set to 64-bit.

To check your settings, right click the project and choose Properties. On the Build tab, check the value of "Platform Target".

Also check your solution's build configuration (Build menu > Configuration Manager) to check all your projects are being built to the same platform.

In both cases, make sure you check the settings both for debug and release mode - otherwise you'll get it working on your machine but not when you deploy it!

My problem was that I was trying to create a ASPX web application in a subfolder of a folder that already had a web.config file, and

So I opened up the parent folder in Visual Studio as a Web Site (Open > Web Site) I was able to add a new item ASPX page that had no issue parsing/loading.

At Dev Server - Use AnyCPU in Solution Plateform and build again. Please refer this screenshot. AnyCPU
