Metaprogramming in C#

By: Einar Ingebrigtsen

Overview of this book

Metaprogramming is an advanced technique that helps developers to automate repetitive tasks, generate scalable code, and enhance productivity in software development. Metaprogramming in C# is a comprehensive guide that will help you reap the full potential of metaprogramming in .NET runtime. You’ll start by learning about the .NET runtime environment and how you can use it to become a more productive developer. You'll learn how to infer types using reflection, use attributes, and create dynamic proxies. You’ll also explore the use of expressions to create and execute code and how to take advantage of Dynamic Language Runtime. But that's not all! You’ll also learn to go beyond inheritance and use method signature conventions to create easily maintainable code. Finally, you’ll dive into the world of compiler magic with Roslyn, where you'll discover how to use Roslyn to generate code, perform static code analysis, and write your own compiler extensions. By the end of this book, you’ll have a deep understanding of metaprogramming concepts and how to apply them to your C# code. You’ll be able to think about types, use attributes and expressions to generate code, and apply crosscutting concerns to improve code quality.

Aspect-Oriented Programming

Throughout the book, you should have noticed a theme: automation. This means writing code that makes your code easier, more maintainable, and takes away repetitive work. In Chapter 13, Applying Cross-Cutting Concerns, we talked about code that could be created for a specific concern and be automatically applied. In this chapter, we will take this concept to the next level and dive into a formalization that is designed for this purpose; aspect-oriented programming (AOP).

In this chapter, we will cover the following topics:

  • What is AOP?
  • Logging
  • Mixins
  • Authorization

By the end of this chapter, you should have a solid understanding of AOP and how it can be used in C# to create more modular, maintainable, and scalable applications.
