Roslyn source generators reduce C# boilerplate by automatically generating code at compile time. You can build custom `IIncrementalGenerator` implementations or consume built-in generators like `[LoggerMessage]` to eliminate repetitive coding tasks.

IIncrementalGenerator provides incremental, cache-aware code generation in .NET. Unlike standard generators, it only re-executes when underlying syntax nodes change, optimizing Roslyn build performance by avoiding unnecessary regeneration of unchanged code.

You can implement INotifyPropertyChanged automatically by creating a custom Roslyn source generator that targets fields marked with a specific attribute. The generator parses the syntax provider and emits the necessary property change notifications during compilation.

Yes, [GeneratedRegex] improves AOT compatibility in .NET by compiling regular expressions at compile time. This source generator eliminates the runtime cost of parsing regex patterns and avoids using dynamic IL emission, which is incompatible with ahead-of-time compilation.

Testing and debugging custom C# source generators involves utilizing specific testing strategies to verify generated syntax and validating diagnostic reporting. You can debug generators by attaching the debugger to the Roslyn compiler process during build execution.

Yes, you can use System.Text.Json source generators for compile-time serialization in C#. They generate highly optimized serialization code at build time, which improves runtime performance and ensures your JSON processing remains AOT-compatible.
