Source Generators hook into the Roslyn compiler via ISourceGenerator or IIncrementalGenerator (preferred in modern .NET). IIncrementalGenerator caches syntax node inputs so it only re-generates code when files with your attribute actually change!

Check out the Microsoft.CodeAnalysis.CSharp NuGet package. Incremental generators are blazingly fast and keep IDE typing responsive.
