                                Hello Jairo Alexander,
                                This problem usually occurs when *.Design.dll assembly files are in the Bin folder. These files are used for internal purposes only and usually are registered in the GAC via the DXperience installer. Moreover, the *.Design.dll assembly files cannot be distributed according to the terms of our EULA.
                                To resolve this issue,
                                - Remove all *.Design.dll assembly files from the Bin folder;
                                - Clear the assosiated "Temporary ASP.NET Files" directories:
                                  c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\
                                  c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\
                                - Rebuild your web application.
                                Please refer to the Q399244: Incompatibility with AjaxControlTollKit - Could not load file or assembly 'Microsoft.Windows.Design.Extensibility, Version =' report, where we discussed this issue in greater detail.
