C# Essentials

Microsoft .NET is an advance in programming technology that greatly simplifies application development, both for traditional, proprietary applications and for the emerging paradigm of Web-based services. .NET is a complete restructuring of Microsofts entire system infrastructure and represents a major learning challenge for programmers developing applications on Microsoft platforms.

This two-day intensive course is designed for the experienced programmer to help you quickly come up to speed on the C# language. It is current to Visual Studio 2008 and .NET 3.5, which introduces important new features such as implicit typing, extension methods, lambda expressions and Language-Integrated Query (LINQ). The new features are covered in a new chapter.

This course concisely covers the essentials of programming using Microsofts new C# programming language. It starts with a brief chapter, .NET: What You Need to Know, which gets you up and running in the .NET environment with a minimum of fuss. The next two chapters cover C# language essentials and object-oriented programming in C#. The next chapter discusses how C# relates to the .NET Framework. The following chapter covers delegates and events. The course includes a succinct introduction to creating GUI programs using Windows Forms. The course concludes with a chapter covering the new features in C#. An appendix provides a tutorial on Visual Studio 2008.

The course is practical, with many example programs and a progressively developed case study. The goal is to quickly bring you up to speed in writing C# programs. The student will receive a comprehensive set of materials, including course notes and all the programming examples.

• The student should be an experienced application developer or architect. Some background in object-oriented programming would be helpful.

On completion of this course, the student should be able to

• Acquire a working knowledge of C# programming
• Learn about important interactions between C# and the .NET Framework
• Learn how to implement simple GUI programs using Windows Forms
• Gain a working knowledge of implicit typing, object initializers, anonymous types, extension methods, lambda expression, LINQ, and other new features in C# 3.0.
