Might sound obvious but do you definitely have AjaxControlToolkit dll in your bin

It looks like you re trying to run it on a version of ASP NET which is running CLR v2  It s hard to know exactly what s going on without more information about how you ve deployed it  what version of IIS you re running etc  and to be frank I wouldn t be very much help at that point anyway  though others would   But basically  check your IIS and ASP NET set-up  and make sure that everything is running v4  Check your application pool configuration  etc
