I have been using ajax extenders in a large web-based app without a hitch until tonite. When I went to add an extender to a new web form, received the error message: "unable to reference extender assembly ajaxcontroltoolkit, Version = 4.1.50401.0,culture=neutral, public key token = (16 character key which I'm not including)"
If I run the app, all existing forms with extenders function as always....but I cannot add extenders to any existing or new form.
I don't have a clue what happened as I was creating forms and adding extenders last nite, but can't now.
Can anybody suggest a solution?
