Clean Code in C#

By: Jason Alls

Overview of this book

Traditionally associated with developing Windows desktop applications and games, C# is now used in a wide variety of domains, such as web and cloud apps, and has become increasingly popular for mobile development. Despite its extensive coding features, professionals experience problems related to efficiency, scalability, and maintainability because of bad code. Clean Code in C# will help you identify these problems and solve them using coding best practices. The book starts with a comparison of good and bad code, helping you understand the importance of coding standards, principles, and methodologies. You’ll then get to grips with code reviews and their role in improving your code while ensuring that you adhere to industry-recognized coding standards. This C# book covers unit testing, delves into test-driven development, and addresses cross-cutting concerns. You’ll explore good programming practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. Once you’ve studied API design and discovered tools for improving code quality, you’ll look at examples of bad code and understand which coding practices you should avoid. By the end of this clean code book, you’ll have the developed skills you need in order to apply industry-approved coding practices to write clean, readable, extendable, and maintainable C# code.

Project – cross-cutting concerns reusable library

In this section, we will be working through writing a reusable library for addressing various cross-cutting concerns. It will have limited functionality, but it will give you the knowledge you need to further expand the project for your own needs. The class library you will be creating will be a .NET standard library so that it can be used for apps that target both .NET Framework and .NET Core. You will also create a .NET Framework console application to see the library in action.

Start by creating a new .NET standard class library called CrossCuttingConcerns. Then, add a .NET Framework console application to the solution called TestHarness. We will be adding reusable functionality to address various concerns, starting with caching.

Adding the caching concern

Caching is a storage technique for improving performance when accessing various kinds of resources. The cache used can be memory, a filesystem...
