The key concepts of program structure in visual| programming C # are programs, namespaces, types, members, and assemblies. A C # program includes one or more source files. A type is declared in a program, the type contains members, and can be organized into namespaces. Classes and interfaces are examples of types. Fields, methods, properties, and events are examples of members. When C # programs are compile
