Answer 1

This problem occurs when your referenced dll may different from your web.config file configuration. You need to reinstall the dll.

Answer 2

Replace:

<assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />

For:

 <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-1.3.0.0" newVersion="1.3.0.0" />

Answer 3

Check the contents of runtime/assemblyBinding section in web.config. I found incorrectly registered dependentAssembly elements after installing Kendo UI package. I manually removed duplicates and the problem disappeared.
