Hi Gregory,
A kind of overlooking really happened indeed!
The thing is, while introducing the
Solution-Wide upgrade we modified the entire engine behind the upgrade process. We missed concentrating on the .NET 2.0 assembly upgrade for we assumed customers would have started porting their applications to the .NET 3.5 assemblies.
What I can do to help you upgrade the references in your current project is send you a previous version of the Telerik WebUI VSExtensions, having the single-project upgrade. You could remove the newer VSExtensions through the Extension Manager, activate the older one and use it for the purpose, then revert back to the newer VSExtensions.
Will this work for you?
Kind regards,
Erjan Gavalji
