CS1. Introduction to C#
Rev. 2.2
Microsoft’s .NET is a revolutionary advance in programming
technology that greatly simplifies application development and is a good match
for the emerging paradigm of Web-based services, as opposed to proprietary
applications. Part of this technology is a new language, C#. This new language
combines the power of C++ and the ease of development of Visual Basic. It bears
a striking resemblance to Java and improves on that language. C# may well
become the dominant language for building applications on Microsoft platforms.
This thorough and comprehensive course is a practical introduction
to programming in C#, utilizing the services provided by .NET. This course
emphasizes the C# language. It is current to Visual Studio 2005 and .NET 2.0.
For students pursuing MCTS certification, this course provides the
C# foundation required for Object Innovations’ series of courses designed to
assist in exam preparation. Further important topics in C#, such as interfaces,
delegates and events, are covered in the follow-on course CS5, .NET Framework
Foundations Using C#. A standalone C# course covering these additional topics
is 410, Object-Oriented Programming in C#.
This course is intended to be fully accessible to programmers who do
not already have a strong background in object-oriented programming in C-like
languages, such as C++ or Java. It is ideal, for example, for Visual Basic or
COBOL programmers who desire to learn C#.
An important thrust of the course is to teach C# programming from an
object-oriented perspective. It is often difficult for programmers trained
originally in a procedural language to start “thinking in objects.” This course
introduces object-oriented concepts early, and C# is developed in a way that
leverages its object orientation. There is thorough coverage of traditional
object-oriented features, such as classes, inheritance, and polymorphism, as
well as newer features like properties and indexers. A case study is used to
illustrate creating a complete system using C# and .NET.
Numerous programming examples and exercises are provided, including
the case study. The student will receive a comprehensive set of materials,
including course notes and all the programming examples. The course includes
two electronic supplements, provided as PDF files. The first covers Visual
Studio 2005, and the second covers unsafe code and the C# pointer type.

Course exercises require Microsoft Visual Studio 2005 on Windows XP
with Service Pack 2. Visual C# 2005 Express Edition can also be used. See the
appropriate course Setup Guide for details.
A good minimal hardware profile for this course would have a Pentium
1 GHz or equivalent CPU, 512 MB of RAM, and at least 4 GB of free disk space for
tools installation and courseware.
