Configuration :: A Duplicate 'system.web.extensions/scripting/scriptResourceHandler' Section Defined?
Jun 22, 2010
I am trying to create an MVC2 web application that will run both on my local development machine (on localhost), and on our central webserver.
Development machine:
Windows 7 Professional, 64bitVisual Studio 2010 (beta)ASP.NET 4.0IIS 7.5
Webserver:
Windows Server 2003 SP2ASP.NET 3.5 SP1 (determined by checking the folders under %SystemRoot%Microsoft.NETFramework)IIS 6.0
Everything works fine when debugging from VS, and I've finally gotten so far that it also works copied to the webserver. However, when I try to copy it to my own local webserver, I get the following error message:
Error Summary
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

I have written my ASP.NET web site code in Visual Studio 2008. When I'm uploading it to the remote server I'm getting an error message about a problem in the web configuration file:
Section or group name 'system.web.extensions' is already defined.Updates to this may occur at the configuration level where it is defined.What is the reason for this error?

I'm trying to read the value in the web.config file for the <jsonSerialization /> element. Here's an example showing where it appears:
<configuration> <system.web.extensions> <scripting> <webServices> <jsonSerialization maxJsonLength="500000"/> </webServices> </scripting> </system.web.extensions></configuration>
So, here's what I did to try and get the value:
[Code]....
But it turns out that the OpenWebConfiguration(null) method call is returning the global web.config file, whereas I want the web.config file for this particular site. If I hard-code in the path to this particular site, then it works--but then my code isn't portable. There must be a way to open the web.config file for the particular site that the code is hosted on--isn't there? Could somebody point me in the right direction?nd, if there's another way I should go about trying to get the maxJsonLength attribute out of the web.config, let me know. I can't just instantiate a JavaScriptSerializer object and inspect the MaxJsonLength property, I already thought of that :-)

Is there any way to read configuration section group of IIS7 by using WebConfigurationManager o anything?
I tried to read the authorization section but WebConfigurationManager.GetSection() returns an 'IgnoredSection' instance.
This is what my code looks like...
authSection = WebConfigurationManager.GetSection("system.webServer/security/authorization", HttpContext.Current.Request.Path)

We are working on a web application and the target deployment includes Windows 2003 64-bit. When we run the application on the 64-bit OS, it gives the following error:
The entry 'asp:System.Web.UI:System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has already been added
The web.config file includes the following:
<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode="Never" theme="esl_theme">
<controls>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</controls>
</pages>
And if we remove the line <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>, it seems to work.
Can somebody understand the problem and take corrective action? The application does not compile on 32-bit OS without this.

I have this error: The configuration section 'connectionStrings' cannot be read because it is missing a section declaration on my site when loading this page [URL]. The rest of the site works [URL] Setup:The server is a hosting company - Mocha Hosting. [URL] contains a phpbb forum. This has been installed via the hosting company's web tool (Plesk). There is a root web.config, but there isn't in the /forum/ folder. The forum folder has been set by the phpbb installation wizard to be a virtual directory and application - and it appears to not have asp.net configured on it. The forum worked BEFORE uploading the root web.config file, and again if i temporarily remove the root web.config.

By default ASP.NET 3.5 Web App project has references to assemblies System.Data.DataSetExtensions.dll and System.Web.Extensions.dll.
With System.Data.DataSetExtensions everything is clear for me, it contains such useful extension methods as DataTable.AsEnumerable() and DataTable.CopyToDataTable().
And what about System.Web.Extensions.dll? What useful members could you mention to use?

I moved a site to another server, it worked fine for a a while, but then crashed. I figured out that System.Web.Extensions.dll was missing, so I copied it again. After a while it was missing again. Using Process Monitor I figured out that IIS (w3wp.exe) deletes the file soon after I copy it to the bin folder. (CreateFile with "Read Attributes, Delete" access.)

I downloaded and installed the AjaxControlToolkit.Binary.NET35.zip.I added Accordion, and add Accordion panels. Building the web site always fails. There are several error messages, like, Type 'AjaxControlToolkit.Accordion' does not have a public property named 'AccordionPane'. I checked the web.config file there are two different versions of System.Web.Extensions and System.Web.Extensions.Design.One is version 3.5 and another is 1.0 See the copy followed,
<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

One of the libraries I am including in my project makes use of System.Web.Extensions 3.5.0.0, which conflicts with my Framework 2.0 application, which uses (C:Program FilesMicrosoft ASP.NETASP.NET 2.0 AJAX Extensionsv1.0.61025System.Web.Extensions.dll). I can think of 3 possible solutions:
Ignore the warning and don't change anything. I am not sure what the application does to handle this.
Add an assembly binding element to my web.config (see below) Configure the application explicitly to use different assemblies (I think this is possible, but don't know how to do it).
However, I am unsure of the implications of each of these decisions. The application seems to work perfectly fine even when I ignore the warnings (solution 1), but ignoring warnings that I don't fully understand bugs me...as does having warnings like this show up at all.

I'm having trouble moving a website from one server to another. It seems to be a problem loading multiple versions of System.Web.Extensions. The code uses version 3.5 in most places but a third party control appears to be needing version 1.0.6. I didn't think this was possible but it appears to be working in it's current situation.
Is there a way I can use the GAC version of System.Web.Extensions for the site but import a dll of version 1.0.6 just for these controls?

I have an ASP.NET project and I want to use some AjaxToolKit Extenders on my pages.
The site is created in VS2010, set to Framework 4.0.
This is what I did:
1) Add reference "AjaxToolKit.dll" to my project.
2) Add to the toolbar the same file for the controls
3) Add "ToolkitScriptManager" to the page source.
This adds the declaration to the source as well.
Right after this I get the following error:
Reference required to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' containing the base class 'System.Web.UI.ScriptManager'. Add one to your project.
