My web form application works fine when it's run in Visual Studio 2013. I published the same application on iis version 6.1.
It's giving the following error.
Webforms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive).
I already have check with multiple solutions given on stackoverflow. most of them suggested to add following line in appsetting in web.config file.
<add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms" />
or change the following from 4.5 to 4.0. but it's futile.
<httpRuntime targetFramework="4.5"/>
Even this could not helped me to find a solution. What is causing this error? and how can this me resolved?
You have to add following configuration in your Web.config file which is going to enable pre-4.5 validation mode. Since None is not its default value if you are using targetFramework="4.5" you have to explicitly add this to your configuration.
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>
I've got a .NET Web API project and on load I'm getting a download of this script called browserLink.
http://localhost:49818/ea93983f23c54f35a63de09646c09159/browserLink
Its associated with .NET Signalr but I'm not using that so I'm not sure why its being included. Any ideas how to turn it off?
Disable Browser Link in Visual Studio 2013.
Do this by editing your web.config file to add the following line to your appSettings section:
<appSettings>
<add key="vs:EnableBrowserLink" value="false"/>
</appSettings>
Note that Browser Link is only used when working in Visual Studio AND the web application is compiled in debug mode, i.e.:
<system.web>
<compilation debug="true" />
</system.web>
In other words, end-users of your site will never make this request.
Iam not able to run the Visual Studio Application with IIS Express. Iam getting an Error “Unable to launch IIS Express” for the first time.
After multiple times debugging,
Iam getting the below error,
If I run IIs express manually through command prompt,iam getting the below error,
I have reinstalled IIS Express but there is no change. I have also modified the application host config file of IIs express by deleting all the site names of application but there is no change.
Iam not able to know the issue. So, plz suggest any solution for fixing this issue.
I had the same problem and the problem is related to the app pool definition which you can find in \users{your username}\mydocuments\IISexpress\config\applicationhost.config.
Find the tag
<add name="Clr4IntegratedAppPool" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated" CLRConfigFile="%IIS_USER_HOME%\config\aspnet.config" autoStart="true" />
and change the managedruntimeversion from "v4.0" to "v4.0.30319" for .net 4.5
<add name="Clr4IntegratedAppPool" managedRuntimeVersion="v4.0.30319" managedPipelineMode="Integrated" CLRConfigFile="%IIS_USER_HOME%\config\aspnet.config" autoStart="true" />
Following suggetions that might be helpful to you>>
Use process monitor to watch the iis-express process to see if there are any permission issues when attempting to start it.
For that, follow this link>>

If problem is security related then, run visual studio in run as administrator mode
As a last resort, you can disable the logging module by modifying the applicationhost.config, which is located in the %userprofile%\documents\IISexpress\config directory.
To do so you will need to comment out a some lines in the file.
Under the <system.webServer>/<globalModules> element, comment out the line
<add name="HttpLoggingModule" image="%IIS_BIN%\loghttp.dll" />
Under the <location>/<system.webServer>/<modules> element, comment the line
<add name="HttpLoggingModule" lockItem="true" />
After saving your changes try restarting iis express.
I got a complicated problem with ASP.Net 4.0 Ajax....I started a website with Visual Studio 2010 on my machine,and added some update panels they used to work fine,but suddenly i got that series of errors when i run my website
Microsoft JScript runtime error: ASP.NET Ajax client-side framework failed to load.
Microsoft JScript runtime error: 'Sys' is undefined
The strange things is that i made a website on the same machine with VS 2010 and the update panels there work perfectly.i took its web.config to my new website and changed just the connection..and i got the same error
I tried to search for a solution but i failed to find any real solution.Can anyone help?
Here is the answer by zhughes from this thread on asp.net forum.
The Reason : the path of the javascript generated by the scriptmanager changes when the URL Routing module is used.
The Solution : Tell the routing API to not route the files with "axd" extension (the files generated by the scriptmanager)
Add this rule to the method where you register the routing rules in Global.asax
routes.Ignore("{resource}.axd/{*pathInfo}");
in addition you should have this section in web.config
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
if you using URL rewrite module, then in each rewrite rule add
<add input="{URL}" pattern="\.axd$" negate="true"/>
under conditions tag, like this:
<rule name="HomeRewrite" stopProcessing="true">
<match url="^home$"/>
<conditions>
<add input="{URL}" pattern="\.axd$" negate="true"/>
</conditions>
<action type="Rewrite" url="/home.aspx"/>
</rule>
I have found that this is a possibly a caching/compression issue and by putting in the following into Web.Config, resolves the issue.
<system.web.extensions>
<scripting>
<scriptResourceHandler enableCaching="false" enableCompression="false" />
</scripting>
</system.web.extensions>
I was having the same problem. I installed VS 2010 SP1 and the problem went away.
I had the same problem and I solved it by run the command aspnet_regiis -i on the folder of the Framework 4.0 (on which my application ran). It was a problem on the Handler Mapping of IIS: this operation fix the problem for me.
See also this post.
Hope this could be helpful.
It may be simply missing part in your web.config like the <Handlers> of <httpHandlers>, my advice is if you have old copy of your web config try it out.
Microsoft JScript runtime error: ASP.NET Ajax client-side framework failed to load.
Add reference like this..
<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add assembly="System.Data.Entity, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
<add assembly="System.Data.Services, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
<add assembly="System.Data.Services.Client, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
This is a common error that happens when you try to call framework javascript function before page have even loaded them.
So ether run your code when dom is ready (eg pageload), ether place your code after the scriptmanager tag, or check to place it after the javascript load from scriptmanager.
I had this problem and sought an answer from the almighty Google, tried various suggestions including the ones above but had no luck. Gave up and moved on to other work, came back a few days later and the problem had disappeared.
I resumed work, made some code changes and published my website and the problem reappeared. Went back to the Google and came across someone who had the problem while using the 3.5 framework. In that case s/he was able to resolve the problem by going to the 'Add/Remove Programs' control panel and selecting the repair option.
I did likewise, repairing the 'MS .NET Framework 4 Client Profile' and 'MS .NET Framework 4 Extended'. That fixed the problem for me.
Hope that solves it for someone else.
in my case, it's IISExpress, switch back to the cassini dev server fix my headache.
I had this problem as well dealing with a master page and in my case it was a "Base" meta setting that was messing me up. I do recall reading another article/blog somewhere where they mentioned an issue with ajax validation across different domains causing this type of error.
So in my case, I had a <base...> reference setting the default url for the site but my dev was obviously a different url...thus conflict and the "ASP.NET Ajax client-side framework failed to load." error.
Removed the base and voila...error gone.

If .Net Framework 4.0 client Profile is not available in your machine , so repair .net Frame work 4.0 or re install .
go to Project Property and select target framework 3.5.
In my case it was the UrlScan tool by Microsoft that was rejecting some URL's requested by Ajax. Disabling it solved the problem.
I have created a simple application with 1 textbox, 1 button and a validator control. When I deploy it to the Windows server 2008, I get the following error.
The WebResource.axd handler must be registered in the configuration to process this request.
I have added the following handler but it still gives the same exception. If I remove the validator control, then it works fine.
<system.webServer>
<handlers>
<add name="Foo" path="WebResource.axd" verb="GET"
type="System.Web.Handlers.AssemblyResourceLoader" />
</handlers>
</system.webServer>
I have searched online but haven't found any solution. has anyone been able to resolve this issue.
thanks
I had this problem and that reason was incompatibility between Coldfusion and some configurations of ASP.NET applications when IIS App pool is in integrated mode. Coldfusion must be disable .
