I am trying to learn AJAX.
I downloaded the first video on this page: http://asp.net/ajax/:
A demonstration of ASP.NET AJAX-"Scott's ToDO List"
I followed the video religiously, but the program didn't run. I went back thru the video several times, couldn't find where I went off the rails. Then I downloaded the code that comes with the video, ran it and THAT doesn't work either!
The message I get follows. What is most surprising is, it seems to be bombing in framework, not in the program.
Any help would be appreciated. I am working in .net 2005
thanks, Laura
