    I am recently updated a web app to visual studio 2013..  When I check in Tools/Extensions and Updates I see Telerik ASP.NET AJAX vs Extentions version 2016.2.603.0. 

    When I view one of my web pages in the design view all of the RAD Controls have this error message:
    EmployeeSectionError Creating Control - rcbAccusedFailed to create designer 'Telerik.Web.UI.RadComboBox, Telerik.Web.UI, Version=2010.2.929.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' 

    Why is version 2010 being refrefenced in the error messge?

    However the application will run and all of the controls work.

    Why do I see this error message in design view and how can I fix it?
