Mastering C# and .NET Framework

Overview of this book

Mastering C# and .NET Framework will take you in to the depths of C# 6.0/7.0 and .NET 4.6, so you can understand how the platform works when it runs your code, and how you can use this knowledge to write efficient applications. Take full advantage of the new revolution in .NET development, including open source status and cross-platform capability, and get to grips with the architectural changes of CoreCLR. Start with how the CLR executes code, and discover the niche and advanced aspects of C# programming – from delegates and generics, through to asynchronous programming. Run through new forms of type declarations and assignments, source code callers, static using syntax, auto-property initializers, dictionary initializers, null conditional operators, and many others. Then unlock the true potential of the .NET platform. Learn how to write OWASP-compliant applications, how to properly implement design patterns in C#, and how to follow the general SOLID principles and its implementations in C# code. We finish by focusing on tips and tricks that you'll need to get the most from C# and .NET. This book also covers .NET Core 1.1 concepts as per the latest RTM release in the last chapter.

Chapter 10. Design Patterns

In this chapter, we're not focusing on the architecture and tools required to manage a solution's life cycle (sometimes called the development ecosystem) but on the quality of the code and its structures in terms of efficacy, precision, and maintainability.

We'll start with the SOLID principles, proposed by Robert Martin, which are gaining more and more recognition and that we can see implemented in different frameworks and technologies.

A basic application will be used to illustrate the distinct principles, and as the requirements evolve, we'll apply different principles and patterns to solve the problems.

Finally, we'll go through the eight most used patterns of the Gang of Four (according to statistics), revising its definitions and purpose to finish with the current list of available patterns created and published after the GoF group published their book.

Therefore, the topics covered in this chapter are as follows:

  • SOLID principles

  • Open/Closed principle

  • Liskov Substitution...
