Online Programming with C# course

This class is an introduction to the C# ("C sharp") programming language. It will cover the concepts and building blocks of the C# programming language, such as how .NET is different from traditional programming, defining variables, control structures, operators, classes and methods. It will provide delegates with a skill base from which they can go on to develop C# applications on either the Windows Forms or ASP.NET platforms.
