    My apologies for posting a question that may have already been answered.  I've searched multiples times and none of the solutions apply to my situation.

    I am receiving this error when I open my default.aspx page immediately after creating the project.  I have not changed any code at all.

    I get Error Rendering Control for RadScriptManager
    I get Error Creating Control for RadAjaxManager

    Could not load file or assembly ‘Telerik.Web.UI, Version 2014.3.1024.45, Culture=neutral,
    PublicKeyToken=121fae7816bda3d4’ or one of its dependencies.  The located assembly’s manifest definition
    does not match the assembly reference. 
    (Exception from HRESULT: 0x80131040)

    I've updated the Telerik Suite since I first had this issue and I still have the issue on newly created projects.

    Resolved - Had to add the control to the GAC.  This article helped which I did find by doing yet another search.

    Now I have to figure out why I don't have the Telerik Toolbox

    I recommend you examine the article below which elaborates on how to resolve toolbox problems:


    Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.

    Thank you.  I deleted the TBD files and after rebooting it worked.
