I am running a 4.0 environment on my development machine (VS 2010 + .NET4) and my server (2008 SERVER + just installed .NET 40). On my dev environment, I don't get any errors, but with the same web config on the server, I get: Error 500.19 - The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration
[code]...
My system: I have installed Windows 7, VS2010 and .NET40 and ASPAJAXExtSetup.msi I'm getting the error below.
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 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:

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)
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.

On attempting to deploy a .net 3.5 website on the default app pool in IIS7 having the framework section set to 4.0, I get the following error.There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined.Commenting off the offending lines didnt help either.

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.

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?

View 1 RepliesI 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.)
