C# Essentials

Current Version: 4.0
Summary

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 Microsoft’s 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 2010 and .NET 4.0, which introduces important new features such as dynamic data type, named and optional arguments, and the use of variance in generic interfaces. The new features are covered in a new chapter. A new appendix covers the fundamentals of Language Integrated Query (LINQ), which was introduced with .NET 3.5.

This course concisely covers the essentials of programming using Microsoft’s 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#. Appendices provide a tutorial on Visual Studio 2010 and an overview of LINQ.

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.
