Overview of this book

The C# programming language is often developers’ primary choice for creating a wide range of applications for desktop, cloud, and mobile. In nearly two decades of its existence, C# has evolved from a general-purpose, object-oriented language to a multi-paradigm language with impressive features. This book will take you through C# from the ground up in a step-by-step manner. You'll start with the building blocks of C#, which include basic data types, variables, strings, arrays, operators, control statements, and loops. Once comfortable with the basics, you'll then progress to learning object-oriented programming concepts such as classes and structures, objects, interfaces, and abstraction. Generics, functional programming, dynamic, and asynchronous programming are covered in detail. This book also takes you through regular expressions, reflection, memory management, pattern matching, exceptions, and many other advanced topics. As you advance, you'll explore the .NET Core 3 framework and learn how to use the dotnet command-line interface (CLI), consume NuGet packages, develop for Linux, and migrate apps built with .NET Framework. Finally, you'll understand how to run unit tests with the Microsoft unit testing frameworks available in Visual Studio. By the end of this book, you’ll be well-versed with the essentials of the C# language and be ready to start creating apps with it.

What are Microsoft tools for unit testing?

If you are working with Visual Studio, several tools help you to write unit tests for your C# code. These tools include the following:

  • Test Explorer: This is a component of the IDE that allows you to view the unit tests, run them, and see their results. The Test Explorer does not work solely with MSTest (Microsoft's testing unit framework). It has an extensible API that allows developing adapters for third-party frameworks. Some of the frameworks that provide adapters for Test Explorer are NUnit and xUnit.
  • Microsoft unit test framework for managed code or MSTest: This is installed with Visual Studio but is also available as a NuGet package. There is also a unit testing framework for native code with similar functionalities.
  • Code coverage tools: They allow you to determine the amount of code that unit tests are covering.
  • Microsoft Fakes isolation framework: This allows you to create substitutes for classes and methods...
