I have been struggling with some ASP AJAX code.  I moved a .NET site from Server 2003 32-bit IIS6 to IIS7 on Server 2008 64-bit.  After a lot of searching and banging my head against the wall, I found a blog on MSDN that told me how to add a binding redirect to my web config file so that the code would use the AJAX built into .NET 3.5.  Here it is.

Thank you, Microsoft MSDN.


    <assemblyBinding xmlns=urn:schemas-microsoft-com:asm.v1>


        <assemblyIdentity name=System.Web.ExtensionspublicKeyToken=31bf3856ad364e35/>

        <bindingRedirect oldVersion=>
