What can stop visual studio from deleting list instances

What could be possible reason for this,

Could not delete list instance ‘Lists/Documents’ from server.
Could not delete list instance ‘Lists/Fruits’ from server.
Deployment conflict resolution for one or more items failed. See the Output Window for details.

Have you tried Deleting the list with PowerShell? You’ll probably get the error message that Visual Studio received.

VS won’t do the cleanup on that scale, it’ll target only the site you set as the Deploy target so you’ll need the PowerShell anyways, then. I might not have understood your comment completely, was it an objection or your plan of action?

Don’t enough rank to just comment. Put in your feature deactivating code to “try” to delete the list instance before the content type is removed. When you remove the content type and list definition, the list instance still stays in the content database.

Also, as a developer, PowerShell is your best friend. It uses the same SP object model.
