Research direction

Explore the quicktype codebase, focusing on the C# language target files (likely src/quicktype core/language/CSharp.ts). The issue requests emitting type aliases (using directives) for top level non object types (e.g., primitives, enums). Currently, quicktype may only emit aliases for object types. Study how using directives are generated for objects and extend that logic to other types. The StackOverflow link in the issue (https://stackoverflow.com/a/9258120/80410) illustrates the desired behavior. Check existing tests in the C# test suite to understand current output, then implement the new feature and add tests.
