How to Read
Each tutorial folder contains:
README.md- Explanation, concepts, and what to expectcsharp/- C# fluent DSL examplesjson/- Equivalent canonical JSON definitions (where applicable)
Start with Tutorial 01 and progress sequentially. Tutorials 07 (Shared Helpers) and 09 (Testing) are C#-only since they cover code organization and test infrastructure.
