There?s a known issue with Visual Web Developer 2008 beta, which will be fixed before the final release. </o> Here?s the problem I ran into. I had both Ajax 1.0 and 3.5 installed on my PC, and even though I explicitly specified I wanted my application to use 1.0 in both the Web.Config file and in my various other files, it was ignoring me and using version 3.5 instead. </o> And that caused the SlideShowExtender to malfunction. I spent hours trying patches to my code and Google-researching to find an answer, and I?m posting this in case anyone else runs into the problem. </o> .Net Framework 3.5 beta comes with <st1:City w:st="on"><st1lace w:st="on">Ajax 3.5 already installed (which I didn?t know). And if you build an application, as I did, in Visual Web Developer 2008 using version 3.5 of the <st1:City w:st="on">Ajax toolkit, and then convert it back to <st1:City w:st="on"><st1lace w:st="on">Ajax version 1.0 in order to deploy it on the web, it may still reference the Ajax 3.5 DLLs even though you?ve told it otherwise. </o> Compounding the confusion was that my application ran fine on my local PC, but wouldn?t run at all on my website. And most the error messages I was getting along the way were fairly misleading. </o> So if you have VWDE 2008 and .Net 3.5 on your machine, and you?re using <st1:City w:st="on"><st1lace w:st="on">Ajax 1.0 and running into the same problem as I, here?s the steps to fix things: </o> Uninstall <st1:City w:st="on"><st1lace w:st="on">Ajax Extensions 1.0 </o> In order to resolve the Multi-targeting issue, run the script located under ?Machine Prerequisites? at: </o> http://blogs.msdn.com/webdevtools/archive/2007/07/30/using-vs-2008-to-target-asp-net-ajax-1-0.aspx</o> </o> Reinstall <st1:City w:st="on"><st1lace w:st="on">Ajax Extensions 1.0 </o> 1. In Window?s Explorer, go to the folder:</o> </o> \Program Files\Reference Assemblies\Microsoft\Framework\v3.5</o> </o> 2. Create a folder entitled ?AjaxDLLsBackup? at this location.</o> </o> 3. Move the following two assembliesfrom </o> </o> \Program Files\Reference Assemblies\Microsoft\Framework\v3.5 </o> </o> to the new ?AjaxDLLsBackup? folder</o> </o> <I style="mso-bidi-font-style: normal">System.Web.Extensions.dll</o>[/I] <I style="mso-bidi-font-style: normal">System.Web.Extensions.Design.dll</o>[/I] </o> At this point, you should be up and running. </o> Oh, the joys of beta testing. Laissez les bons temps rouler. (Let the good times roll) </o> Lar
