This document provides answers to common questions about object-oriented programming concepts in C#. Key points addressed include: 1) Static classes cannot be instantiated and can only contain static members. 2) Value types like structs are sealed and cannot inherit from other classes or structs. 3) Structs can be instantiated without using the new operator and do not support inheritance but can implement interfaces. 4) Sealed, abstract and static classes cannot be used as base classes and abstract classes cannot be instantiated. Destructors also cannot have access modifiers.
