Overview

  • Course Overview
  • 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 2019, .NET Framework 4.7.2 and C# 8.0. Important newer features such as dynamic data type, named and optional arguments, the use of variance in generic interfaces, asynchronous programming keywords, tuples, and nullable reference types are covered in a final chapter. Supplements cover Visual Studio 2019, the fundamentals of Language Integrated Query (LINQ), and unsafe code and pointers. 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 procedural programmers who desire to learn C#.
  • Audience
  • Programmers who need to design and develop C# for the .NET framework.
