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
