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 Framework is the original implementation of .NET, running on Windows. .NET Core is a new package-based implementation that is cross-platform, running on Mac and Linux besides Windows. .NET 5.0 is the next version of .NET Core and is the main implementation of .NET going forward. .NET Framework 4.x continues to be supported. This two-day 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 2019, .NET 5.0 and C# 9.0. Important newer features such as dynamic data types, named and optional arguments, tuples, asynchronous programming keywords, nullable reference types, and immutable record types are covered. This course concisely covers the essentials of programming using Microsoft’s C# programming language. It starts with an overview of .NET architecture and the basics of running C# programs in a .NET environment. 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 2019, an overview of LINQ, and coverage of unsafe code and pointers in C#. 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.
