                                  Thank you for contacting us. Our libraries do not require this "Windows" specific assembly.

                                  all followed the example below and could not solve my problem .. the error keeps happening. What is making me more surprised is the fact that there are times that the app works, and minutes later stops working, as if the server blocking the dll ajaxcontroltollkit.dll. começarama but these problems happen after that I started to use the DevExpress dll. if I make an application without DevExpress does not happen this error.
                                  I do not know what to do, I have done all

                                  Hello Amz,
                                  Thank you for your reply.
                                  Would you please provide us a simple sample and configuration (OS and IIS versions) of the target server. If we can reproduce this issue on our side, we will try to determine its cause or find a workaround.
                                  Best regards,

                                  Thank you for providing us a sample application. We need some time to prepare a corresponding virtual machine and test the project there. We will inform you when we have any results.

                                Hello Arnaldo,
                                Thank you for your patience. We have reviewed your project and found out that this issue is caused by using the *.Design.dll assembly files 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 "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files" directory (intended for ASP.NET v4 web applications);
                                - Rebuild your web application.
                                We have attached a screencast that illustrates our statements in action.
                                Thanks,
                                Larry
