telerik ajax ASP visual basic

I'm update telerik asp.net ajax to(2019_1_215) in visual studio(2019) and I have a problem

Error Creating control..failed to create designer

In telerik support page, they say that I have to replace the files in bin folder of project,but when I did these,I faced a new problem

'Could not load file or assembly 'Telerik.Web.UI, Version=2019.1.211.35, Culture=neutral, PublicKeyToken=*********' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'

Please make sure that the Telerik.Web.UI.dll and the Telerik.Web.Design.dll are from the same installation and they have the same version.

After that add references to both dlls in the ASP.NET Web Forms application in Visual Studio and rebuild the app.
