2.5 Summary

• C# is the native language for the .NET Common Language Runtime.
• The object-oriented nature of C# requires the high level structure of a C# program to be
defined in terms of classes, whose detailed behaviours are defined by their statements.
• A large part of the power of C# comes with the common .NET Framework API, which
provides a large set of classes, including ones for encryption, TCP/IP socket programming,
and graphics.

• Web user controls are derived from System.Web.UI.UserControl namespace.
• The Page class inherits from the TemplateControl class, which in turn inherits from the
Control class.
