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 Windows messaging subsystem


All Windows-based applications are event-driven. This means that they don't make explicit calls to functions in the OS APIs. Instead, they wait for the system to pass any input to them. So it's the system that's the one in charge of providing that input.

The system's kernel is in charge of converting hardware events (users' clicks, keyboard entries, touch screen gestures, the arrival of bytes in a communication's port, and so on) into software events, which take the form of messages addressed to a software target: a button in a window, a textbox in a form, and so on. After all, this is the soul of the Event-driven Programming paradigm.

I'll start with a section that deals with how .NET can use low-level resources of the operating system, in other words, how our applications can communicate and use the core functionality of our operating system, despite being coded using distinct models, with distinct data types and calling conventions. This technique permits...
