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 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

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

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.
This group section cannot be printed because its condition field is nonexistent or invalid. Format the section to choose another condition field. Error in File Detailed_CrystalReport {9C8154B9-5093-457C-9E6A-2A1D63E7E866}.rpt: Invalid group condition.

View 5 RepliesI created an ASP.NET REST service (using WCF) and access it through one of my .aspx page. the problem is that when I publish (precomile) my code to the web server, I get an error :
"ThunServ not defined" in the Javascript console of my browser.
don't know what's causing it and how to solve it.
I created a small new webservice for AutoCompleteExtender and for some reason I am getting "type System.Web.Script.Services.ScriptService is not defined" error. I Googled this and found a few threads about similar issues but was unable to resolve mine. Here is the example of the code:
[Code]....
When I add Imports System.Web.Script.Services I get "Namespace or type specified in the Imports 'System.Web.Script.Services' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases".
I've tried adding Reference to System.Web.Extensions and it didn't do anything. What could be the problem?
I've set up a strongly-typed View and a controller method to save the object represented in that View. The object in question is from a class that uses named parameters with default values. This is not a database object, but rather is the intermediate object that is used for the display and user input. It gets translated into a database object in the service class. Anyway, when I attempt to save the object, I get the following error:
System.MissingMethodException: No parameterless constructor defined for this object.
This is kind of aggravating. I can add a parameterless constructor to the class, and then everything works just fine. I just don't understand why it is necessary. I'm new to named parameters with default values, but the reading and such that I've done has described that method calls with default values do not have to have a 'no-parameter' implementation. You can just call the method with any or none of the parameters specified and everything works as expected. If there is a 'no-parameter' implementation and no params are passed, then that one is used, since it is more specific than the one with default values. Is the behavior somehow different when this is used in the constructor of a class? Why would I have to include a parameterless constructor when I have all the values accounted for? Is the runtime creating an object on the fly as the save method executes, which requires this? The method is like this:
[Code]....
I'm wondering if the object is instantiated by the runtime in order to populate the method parameter, and then assigned values from the form collection. I suppose that would make sense, but I do not understand why this causes an exception. For what reason would a parameterless constructor be required?

I want to deploy a website in a computer where no webmatrix is installed. What are the requirement to run the website without webmatrix? And how do I configure IIS to run in startup with the site path?
View 4 RepliesBy 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.)

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 a site written for ASP.NET using a library written for ASP. The library resides in a dll and the site calls it to get the number of leave days an employee has left from a database. The dll was outsourced so I don't have access to the source.
I've set up the database and visual studio project locally. When I run the site and login to the system, an error message is displayed where the leave days should be displayed but the site runs normally. If I register the dll using regsvr32, the leave days are displayed when I login, but when I try to browse the rest of the site, the session is dropped and I'm automagically logged out. If I deregister the dll, then I can browse the site once I've logged in again but, once again, the error is displayed.
