Here are few references that might help: https://www.c-sharpcorner.com/article/working-with-default-interface-implementation-in-c-sharp-8-0/ https://www.c-sharpcorner.com/article/interfaces-in-c-sharp8-0/ https://www.c-sharpcorner.com/forums/after-c-sharp-80-how-interface-are-different-then-abstract-class#:~:text=Use%20an%20abstract%20class%20to,class%20to%20provide%20default%20behavior.&text=Use%20interfaces%20to%20introduce%20polymorphic,type%20to%20support%20numerous%20behaviors. ,, Please let me know if this doesn't help you :)
