object based languages doesnt support Inheritance where as object oriented supports. c# is a object oriented language because it supports inheritance and asp.net is not a langugae it is a technology

If the language supports ony 3 features i;e (data encapsulation,data abstraction $ polymorphism).then it is said to be object based programming language. If the language supports all the 4 features i;e(encapsulatio,abstraction,polymorphism $ also inheritance )..then it is said to be object oriented programming language.
