ASPNET AJAX Fails to load on Page Refresh

Posted on 2008-11-12
Last Modified: 2013-11-08
I am using ASPNET AJAX, VS2008, Framework 3.5. I have ASPNET AJAX working fine in many places. I have a page which has several AJAX controls on it all of which work fine, except when the page is refreshed (via F5) it gives the infamous 'ASP.NET Ajax client-side framework failed to load'. The usual fix doesn't work because I already have AJAX working its not a web.config issue. I'm stumped any ideas would be welcome.

    Turns out that Vista (IIS 7) was the cause of the problem this blog was what helped me solve the problem

    I was missing this:

    <add name="ScriptResource" preCondition="integratedMode"  
    verb="GET,HEAD" path="ScriptResource.axd"  
    type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
