408.  Object-Oriented Programming Essentials with C# and .NET

Rev. 1.0

 

This course introduces the essential skills necessary for developing object-oriented programs on the Microsoft .NET platform. Understanding object-oriented programming (OOP) is essential for working with Microsoft .NET.  As new as the Microsoft .NET platform is, experience has already shown that programmers who do not understand OOP have a significantly more difficult time in understanding and starting to work with .NET, even if they have a significant development background.

 

By the end of course, not only will programmers be able to start thinking in OOP terms, they will know how to build and debug C# programs using the .NET class libraries and Visual Studio .NET.  A great deal of time will be spent with student labs and hands-on demonstrations.

 

The course discusses the traditional object-oriented features of C# such as classes, encapsulation, composition, inheritance, and polymorphism as well as other features such as exceptions, properties, delegates, events, and interfaces. Programming to interfaces is a very important concept in modern OOP thinking and is fundamental to the .NET type system. Several fundamental interfaces and classes of the .NET Framework Class Library will be introduced. In addition, we will show how you can implement design patterns using C# and the class library. Design patterns are a product of modern thinking on object-oriented design and programming that emphasizes programming to interfaces, and using object composition over class inheritance. The course includes a succinct introduction to creating GUI programs using Windows Forms. A final chapter provides an overview of .NET, using the perspective gained from studying C# and object-oriented programming.
