A namespace is essentially a collection of related member types used to implement a specific functionality.
This section of the workshop provides information on selected namespaces used in the development of dynamic ASP.NET Web applications.
Namespaces in the .NET Framework consists mainly of class types, along with the relevant structure, enumeration, and delegate types that provide the interfaces for programming specific application needs.
Each of the member classes in turn define a set of properties, methods and events that enable the class to accomplish particular tasks.
