In one of my projects which is in UAT , I have used your uploadBox control version 11.3.3035 successfully and it works fine.. BUt now I have upgraded to your new version of essential studio. I managed to add the control to the tool box and add reference as well bt it comes up with an error
Error4Reference required to assembly 'System.Web.Extensions, Version=184.108.40.206, Culture=neutral, PublicKeyToken=31bf3856ad364e35' containing the implemented interface 'System.Web.UI.IScriptControl'. Add one to your project.
Ca you please help.. I would likwe to use this version of the control as that works fine in UAT
