I open the assembly BGS, there is lightweight subassembly BoltGaikaChaiba. In BoltGaikaChaiba resolved virtual assembly virt1. Subscribe to the event RenameItemNotify and FeatureManagerTreeRebuildNotify of BGS.
If you rename virt1 fired FeatureManagerTreeRebuildNotify, event RenameItemNotify not fired - fired only if BoltGaikaChaiba is resolved and subscribe to the event RenameItemNotify. How, then, to learn that the name virt1 changed to another?
