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 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 2017, .NET Framework 4.7 and C# 7. Important newer features such as dynamic data type, named and optional arguments, the use of variance in generic interfaces, asynchronous programming keywords, and tuples are covered in a final chapter. An appendix covers the fundamentals of Language Integrated Query (LINQ).

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 newer features in C#. Appendices provide a tutorial on Visual Studio 2017, an overview of LINQ, coverage of unsafe code and pointers in C#, and using .NET Framework 4.7.

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 dynamic data type, named and optional arguments, and other new features in C# 4.0
• Learn how to do asynchronous programming using new keywords in C# 5.0
• Become aware of new features in C# 6.0 and C# 7.0
