Upgrade site from .Net Framework 2.0 to 3.5

I just tried to update my site to .Net Framework 3.5 (from 2.0) and get the following exception trying to load any page:


System.InvalidCastException: Unable to cast object of type 'System.Web.Configuration.ScriptingAuthenticationServiceSection' to type 'System.Web.Configuration.ScriptingAuthenticationServiceSection'.
at System.Web.Configuration.ScriptingAuthenticationServiceSection.GetConfigurationSection()
at System.Web.Security.AuthenticationService.EnsureConfigLoaded()
at System.Web.Handlers.ScriptModule.ShouldSkipAuthorization(HttpContext context)
at System.Web.Handlers.ScriptModule.AuthenticateRequestHandler(Object sender, EventArgs e)
at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

It appears to be some sort of version conflict since the assembly names are the same. The site worked in my dev environment just fine. I believe all the references in the web.config are referencing 3.5 assemblies. Has anyone else successfully updated to 3.5? Are there any special web.config settings I need to add to work with DiscountASP?

The only reference I could find while google'ing this issue is a conflict with the incorrect version of ajaxControlToolkit. I use the control toolkit but I updated that and it worked fine locally.

Thanks,

Ray

 

Go to the codeplex site for the recently updated 3.5 version of the ControlToolkit.
Both toolkits are available now, 2.0 and 3.5 enabled.

Thatwas the first thing Itried. The download was dated Nov. 29thand it didn't make a difference.

 

In AjaxControlToolkit-Framework3.5.zip the compiled AjaxControlToolkit.dll is dated 28 Nov 2007.

Currently:
Assembly version 3.0.11119.25533
Product version 3.0.11119.0

Is that the one you tested?

Note: There were some bugs in the initial release apparently.
Take a look at David's post:

Salute,

Yes, that is the version I am using. That web link is referring to using the control toolkit in the designer, which I am not doing.It also seems if it was some sort of version issue with my version of the ajaxControlToolkit that it would not work in my local development environment either. I will have to try to create a very small sample from scratch to see if that works on the hosted site.

Thanks.

 

Hi,
I have solved it removing the xmlns attibute from <configuration> element of web.config file.

That worked for me as well. Thanks.
