Hi Guy,

I suffered from this error for several days and also try to find the solution for several days. At last I found the very important feature which I omitted, the configuration file has the inherit feature. (http://msdn.microsoft.com/en-us/library/ms178685.aspx)

So when you meet this error, you need to check if the parent virtual folder also contain the web.config which contain the conflict setting

For example , contains between the following setting, if yes , please delete it .

<httpModules><add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/></httpModules>

Thanks very much . I would like to clear some concept , :)

1.creating a brand new ASP.NET site : what's the mean?

2. why I need to run the application not under a Virtual dictory.

Make sure your not running under a Virtual Directory.

Also, if that doesn't seem to work. I suggest creating a brand new ASP.NET site and taking that Web.config the new site creates and bring it over to your site while changing the name of the old web.config.

That should fix it if nothing else works.

Parser Error Message: The entry 'ScriptModule' has already been added.

Then, after I add a remove tag to web.config for scriptModule before the entry that adds it...... I get....

Exception Details: System.InvalidCastException: Unable to cast object of type 'System.Web.Configuration.ScriptingAuthenticationServiceSection' to type 'System.Web.Configuration.ScriptingAuthenticationServiceSection'.

I've been searching the net and the forums like mad, but I can't figure this out.

I am thinking that perhaps my configuration on the web server is screwed because of all the various flavors of .net framework, but I really have no clue.

If anyone has any ideas I'd really appreciate any help at all....

I'm trying to get this site set up for a high scool and I'm getting nowhere.

Thanks!

hey jagjot.

When I upgraded to 3.5, I also was fed up with the web.config. my solution was to create a NEW AJAX enabled website and get the Web.config file from that and move it over to my existing site. Then I added the nessary things to it to get it up and running again.

Also, just so you might be aware, you might not want to include your connection strings or emails in forums that are inside the web.config file. It can have devestating consequences if someone wasn't ethical.

This can happen if there are two HttpModules named "ScriptModule". This can mysteriously happen if you are running a virtual directory under an asp application that already has the module defined. You can either remove the HttpModule declaration <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> from the VD web.config, or all a remove node

<remove name="ScriptModule" />

just before adding it back.

On my development system everything is running fine, when i publish to my beta server (SBS 2003 - *no* VS installed) I get the following error:

Parser Error Message: The entry 'ScriptModule' has already been added.

Removing this line resolves the issue but then presents me with various errors relating to not being able to load System.Web.Extensions... If i can understand why the first issue is occuring this would help! Any clues?
