How to modify this piece of code in web config ? it gives runtime error since i didnt merge them.
<pages><namespaces><add namespace="System.Web.Optimization" /></namespaces><controls><add assembly="Microsoft.AspNet.Web.Optimization.WebForms" namespace="Microsoft.AspNet.Web.Optimization.WebForms" tagPrefix="webopt" /></controls></pages><pages><controls><add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35" /><add namespace="AjaxControlToolkit" assembly="AjaxControlToolkit" tagPrefix="asp" /></controls></pages>
Also how to find out Publickey token? I tried sn.exe -T System.Web.UI.dll in command prompt but it shows sn command is invalid.
