C# Source Generators Explained Boosting Compile-Time Productivity

Harness the power of automatic code generation to write cleaner, faster, and more maintainable C# applications
Are you tired of writing repetitive boilerplate code? Do you wish there was a way to automate tedious coding tasks while maintaining type safety and compile-time verification? C# Source Generators are the game-changing feature you've been waiting for.
In "C# Source Generators Explained," you'll master the art of writing code that writes code. This comprehensive guide takes you from basic concepts to advanced implementation, showing you how to leverage the Roslyn compiler platform to generate clean, efficient C# code during the compilation process.
What makes this book essential for modern C# developers:
Learn a cutting-edge skill that puts you ahead of the competition in the .NET ecosystem
Automate repetitive tasks like creating DTOs, implementing interfaces, and generating boilerplate
Improve application performance by moving work from runtime to compile time
Write more maintainable code by centralizing repeated patterns in generator logic
Reduce bugs with compile-time verification instead of runtime reflection
This isn't just another theoretical programming book. Each chapter builds on practical, real-world scenarios that you'll encounter in professional development. You'll work through step-by-step examples and complete projects that you can immediately apply to your own codebases.
Inside this comprehensive guide, you'll discover:How to set up and configure your development environment for source generationTechniques for traversing and analyzing syntax trees using the Roslyn APIMethods for generating clean, well-formatted code that integrates seamlessly with your projectsStrategies for debugging and testing source generators effectivelyAdvanced patterns for building incremental generators that optimize compile-time performancePractical projects you'll build include:An automatic ToString() generator that creates optimal string representations of your modelsA dependency injection helper that registers your services automaticallyCustom mappers that eliminate the need for manual object-to-object transformationsConfiguration parsers that validate your settings at compile time instead of runtimeWho is this book for?
This guide is perfect for intermediate to advanced C# developers who want to level up their skills. Whether you're building enterprise applications, working on open-source projects, or developing personal tools, the techniques in this book will transform how you approach C# development.
While some familiarity with C# and .NET is assumed, you don't need prior experience with code generation or the Roslyn compiler. The book guides you through each concept with clear explanations and practical examples.
Why learn source generators now?
As applications grow more complex and performance requirements become more demanding, compile-time code generation is increasingly essential in a professional developer's toolkit. Source generators were introduced in .NET 5 and have been enhanced with each subsequent release, making this the perfect time to master this powerful feature.
By the end of this book, you'll have the knowledge and confidence to implement source generators in your own projects, dramatically reducing repetitive code while improving both the quality and performance of your applications.
Stop writing the same code over and over again. Let your code write code for you.
