Hey,
Have you guys considered providing an upgrade wizard accessible from within VS that automatically scans all projects and upgrades their referenced assemblies to the latest installed versions.
Competitors such as Telerik already do this. After scanning the VS projects in the solution it provides the options to upgrade to versions that have been installed on the system. Saves a ton of time for those such as myself that have many projects to manually upgrade one-by-one.
Just a thought
Best regards,
