Five common mistakes to check when using JSON-to-C# code generators

JSON-to-C# generators speed up development by eliminating boilerplate code, but their output requires careful human review before use in production. Developers should verify that properties correctly reflect whether fields are required, nullable, or optional, and ensure numeric types like int are not used where long or decimal may be needed. Semantic string values such as timestamps, UUIDs, and currency amounts should be mapped to appropriate types like DateTimeOffset, Guid, or decimal. Empty arrays in sample JSON provide no type information, so generators may infer incorrect collection element types without a representative item present. Choosing between records and classes also matters, as records suit immutable data transfer while classes better support identity, mutation, and framework integration.
