>>>I am running VS2008 with an older version of the Ajax toolkit installed. I would very much like to take advantage of the new content editor in the latest 3.0.30512 release. I downloaded the DLLs but I am unsure where to place these so that I can use the controls from to ASP.Net toolbox. Can someone shed some light on this?
