Hello All,
I have recently inherited a web application, which I am now the owner of. Unfortunately I am struggling to run the application in debug mode within Visual Studio. I am being met with a handful of critical errors and loads of warnings relating to multiple
pages.
I am convinced that the issue is due me using a newer version of the Ajax Control Toolkit as the error list is throwing up two notable errors:
1) Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The system cannot find the file specified.
2) Unrecognized tag prefix or device filter 'asp'.
All of the "problem pages" have the following code referencing the Ajax Control Toolkit near the top of the page.
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
I am a novice developer so I admit that perhaps I may be missing something obvious. I have looked online and if I'm honest, I've just been left more confused.
My questions are:
How can I identify the version of the Ajax Control Toolkit that the original developer used?
Is there a method to easily update the web application to utilise the latest version of the Ajax Control Toolkit?
Is my only option to install older versions of the Ajax Control Toolkit (one by one) and to attempt debugging until I find the correct version?
Any advice would be most welcomed.
Many thanks.
