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.

Performance implications

One of the most important things to keep in mind when working with metaprogramming in C# is its potential impact on performance. When it comes to metaprogramming in C#, there are a few key performance implications to keep in mind:

  1. Additional runtime overhead: Metaprogramming typically involves additional runtime overhead compared to traditional programming techniques. This is because it often involves dynamic code generation or manipulation, which can require extra processing time and memory usage. For example, if you use reflection to dynamically invoke methods or access properties, this can be slower than calling the method or property directly.
  2. Increased memory usage: Metaprogramming can also lead to increased memory usage, especially if you’re generating or manipulating objects dynamically. This can result in higher memory usage, or even memory leaks if you’re not careful. For example, if you’re using reflection to dynamically...
