Hi
I got this dialog pop up when it was trying to upgrade my solution which had a few web sites in it.
It seemed to get lost. I dont know what the VS dialog with 'Description' is all about.
Not sure what triggers it to say it needed an update and yet there is nothing to update.
Its possible that there is a backup folder that it created from a previous upgrade and it is looking at an old DLL in that project.
Anyway, sure you will sort it out :)
Thanks
Doug
We have a WebForms application with Telerik AJAX components which we have successfully upgraded using the wizard for years. Starting with product version 2025.4.1210 and persisting in the latest version, 2025.4.1321, the upgrade wizard fails with the following error message.
The Telerik extension to VS is up to date, and it doesn't seem to help to run this in VS 2022.
An error occurred while running the wizard.
