  3. 3. Namespace • A Namespace in Microsoft .NET is like containers of objects. • Main goal of using namespace in .NET is for creating a hierarchical organization of program. • In this case a developer does not need to worry about the naming conflicts of classes, functions, variables etc., inside a project. • The advantage is that every namespace can contain any number of classes, functions, variables and also namespaces etc., whose names are unique only inside the namespace.
