A new dependency injection framework will be used for the code. By avoiding ObjectManager in Magento 2, you won’t face multiple issues caused by the improvement. source:https://firebearstudio.com/blog/magento-2-objectmanager-use-cases.html
If Magento injects the new dependency, why it is not affecting any child class which we have extended during development?
Any explanation would be appreciated.
Thanks in advance..!
