am working with an application in asp.net. In my application have some Telerik controls of version 2012.2.815.40. That application is working fine.
I Upgraded telerik controls to Telerik.web.ui.dll Version 2013.1.417.45.
When an application is build its getting errors like,"The type or namespace name 'Telerik' could not be found (are you missing a using directive or an assembly reference?)"
Please tell me the solution as soon as possible
