C# 7 and .NET: Designing Modern Cross-platform Applications

By: Mark J. Price, Ovais Mehboob Ahmed Khan

Overview of this book

C# is a widely used programming language, thanks to its easy learning curve, versatility, and support for modern paradigms. The language is used to create desktop apps, background services, web apps, and mobile apps. .NET Core is open source and compatible with Mac OS and Linux. There is no limit to what you can achieve with C# and .NET Core. This Learning Path begins with the basics of C# and object-oriented programming (OOP) and explores features of C#, such as tuples, pattern matching, and out variables. You will understand.NET Standard 2.0 class libraries and ASP.NET Core 2.0, and create professional websites, services, and applications. You will become familiar with mobile app development using Xamarin.Forms and learn to develop high-performing applications by writing optimized code with various profiling techniques. By the end of C# 7 and .NET: Designing Modern Cross-platform Applications, you will have all the knowledge required to build modern, cross-platform apps using C# and .NET. This Learning Path includes content from the following Packt products: • C# 7.1 and .NET Core 2.0 - Modern Cross-Platform Development - Third Edition by Mark J. Price • C# 7 and .NET Core 2.0 High Performance by Ovais Mehboob Ahmed Khan

Unit testing functions

Fixing bugs in code is costly. The earlier a bug is discovered, the less expensive it will be to fix. Unit testing is a great way to find bugs early in the development process. Some developers even follow the principle that programmers should create unit tests before they write code. This is called Test Driven Development (TDD).

Microsoft has a proprietary unit testing framework known as MS Test, which is closely integrated with Visual Studio. However, to use a unit testing framework that is compatible with .NET Core, we will use the third-party framework

Creating a class library that needs testing with Visual Studio 2017

In Visual Studio 2017, add a new ClassLibrary (.NET Standard) project named CalculatorLib, as shown in the following screenshot...
