BC30002 Type 'Global.AjaxControlToolkit.ToolkitScriptManager' is not defined

This error was reported for 19 designer files when I upgraded AjaxControlToolkit to the latest version (20.x)

the ToolkitScriptManager was removed from AjaxControlToolkit in about v. 15 as it is replaced by the standard asp.net script manager.

We cannot edit the designer files because they are “generated”
