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.


For example, CAPMS-SGPMC C:\Users\dertinn\source\repos\CAPMS-SGPMC2\Source\CAPMS-SGPMC\a_e.aspx.designer.vb 23

Originally I tried doing a rename of all the references to ToolkitScriptManager in the aspx files.
This did not resolve the error reported for the designer file, such as the one above and triggered additional errors as well.

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

The solution below eliminated the error and triggered the regeneration of the associated designer file(s).

Currently, I did it one by one, will investigate if there is an easier way later.
