Source Generators
Source Generators are a C# compiler feature that allows developers to write code that runs during compilation to generate additional C# source files, which are then compiled along with the rest of the project. They enable compile-time code generation, reducing runtime overhead and improving performance by automating repetitive tasks like boilerplate code creation. This tool is part of the .NET ecosystem and integrates seamlessly with the Roslyn compiler.
Developers should learn Source Generators when working on large-scale C# projects that involve repetitive code patterns, such as generating serialization code, implementing design patterns like MVVM, or creating performance-critical applications where runtime reflection is costly. They are particularly useful for reducing manual coding errors, improving maintainability, and enhancing application startup times by moving code generation to compile-time.
