I've finished simple asp.net web application project, compiled it, and try to test on local IIS. I've create virtual directory, map it with physical directory, then put all necessary files there, including bin folder with all .dll's In the project settings, build section, output path is bin\ So when i try to browse my app i got:

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 'AmeriaTestTask.Default'.

Source Error: 


Line 1:  <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="AmeriaTestTask.Default" %>
Line 2:  
Line 3:  <%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolkit" %>


Source File: /virtual/default.aspx    Line: 1 

Have read similar problem posts and solution was to set output path to bin\, but it is defalut for my project.

I know i am too late to answer but it could help others and save time.

Following might be other solutions.

Solution 1: See Creating a Virtual Directory for Your Application for detailed instructions on creating a virtual directory for your application.

Solution 2: Your application’s Bin folder is missing or the application’s DLL file is missing. See Copying Your Application Files to a Production Server for detailed instructions.

Solution 3: You may have deployed to the web root folder, but have not changed some of the settings in the Web.config file. See Deploying to web root for detailed instructions.

In my case Solution 2 works, while deploying to server some DLL's from bin directory has not been uploaded to server successfully. I have re-upload all DLL's again and it works!!

Parser Error when deploy ASP.NET application, This error is always related to a bad deployment. Either that code file wasn't published or your missing an assembly somewhere. Best Regards,. I had an ASP.NET Web Site, but I migrated my files into a Web Application Project. Now, after I completed moving the files to the new project, everything works all right locally, but not at the remote server.

I had the same issue.. Ran 5 or 6 hours of researches.. Simple solution seems to be working.. I just had to convert my folder to application from iis.. It worked fine. (this was a scenario where I had did a migration from server 2003 to server 2008 R2)

(1) Open IIS and select the website and the appropriate folder that needs to be converted. Right click and select convert to Application. It is here.. http://www.windowstechinfo.com/2014/09/solved-an-error-occurred-during.html

Sometimes it happens if you either:

  1. Clean solution/build or,
  2. Rebuild solution/build.

If it 'suddenly' happens after such, and your code has build-time errors then try fixing those errors first.

What happens is that as your solution is built, DLL files are created and stored in the projects bin folder. If there is an error in your code during build-time, the DLL files aren't created properly which brings up an error.

A 'quick fix' would be to fix all your errors or comment them out (if they wont affect other web pages.) then rebuild project/solution

If this doesn't work then try changing: CodeBehind="blahblahblah.aspx.cs"

to: CodeFile="blahblahblah.aspx.cs"

Note: Change "blahblahblah" to the pages real name.

"Server Error in '/' Application" or "Parser Error", Check that the codebehind class is public partial class TestCert:Page { } Also try changing CodeBehind="TestCert.aspx.cs" to  Be sure that your DLLs of your project are in the proper path. You may set the output path of you build in another folder outside your project, and when, for example, the project runs and searches for DLLs in the bin folder, it doesn't find them. – user1897631 Dec 12 '12 at 11:26

Try changing CodeBehind="Default.aspx.cs" to CodeFile="Default.aspx.cs"

  • Parser errors tend to mean that your ASPX pages are not well formed.
  • Thanks for reply. I've no warnings in VS2010 and from IDE project runs just fine.
  • It will. Did you load the page up in your local environment? (dev web server, IIS express or full IIS locally)
  • Yes it is local enviroment, i've workstation Win7 x64 and IIS 7.5 installed
  • Look at the ASPX. Make sure the markup is all valid - that it is good XML.
  • worked for me too. Thanks. For all the other people facing this problem and trying this solution, please copy all the code from the old global.asax exactly and paste it in the new global.asax file as it is. For those, who don't know how to add a global.asax in your project, directions are given on this link: stackoverflow.com/questions/21346969/… But please again, make sure you copy the code from the old global.asax exactly as it to new global.asax and it should then work. Goodluck.
  • It worked, but I don't understand how does it work. Please explain.Your link is not working.
  • Site works again. I think its like adding a separate folder will not create the execution environment. IIS will treat it as just a folder. ones you turn the folder into, application it will enable execution using application pools. such as .net/c# environment etc. anyway , to me it was a misleading message!
  • Check in IIS => Sites => Default Web Site => YourProject Right click and check physical path in Basic Setting.
