"The Design Table feature was empty, so it has been removed from the tree".. dialogs when I open an assembly after updating to sp4 2011.
I have saved this file a number of times.. still same error. There is no Design Table in this assembly. Never was as far as I know. It would load fine with sp3.
I have tried deleting any 'extra' hidden and suppressed features not being used, no luck.
the file is the raw one before my attempted fixes.
any ideas what's happening?
