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.

The SOLID principles


Some programming guidelines have a wide, general-purpose intention, while some are designed to fix certain specific problems. Thus, before talking about the specific problems, we should review those features that can be applied in many different scenarios and solutions. I mean those principles that should be taken into consideration beyond the type of solution or specific platform to program for.

Moreover, this is where the SOLID principles (and other related problems) come into play. In 2001, Robert Martin published a foundational article on the subject (http://butunclebob.com/ArticleS.UncleBob.PrinciplesOfOod), in which he picked up a set of principles and guidelines that, in his own words, focus very tightly on dependency management, its inconveniences, and how to solve them.

To explain this further in his words, poor dependency management leads to code that is hard to change, fragile, and non-reusable. Reusability is one the main principles of OOP, along with maintainability...
