During August 2025, Archomeda enhanced the microsoft/kiota repository by expanding the C# code generator to support nullable primitive types, specifically integers and booleans, within union wrappers. This work involved updating the code generation logic and extending the test suite to ensure reliable handling of nullable primitives in generated C# code. Archomeda also addressed a .NET compilation issue that arose when unions contained collections of integers and booleans, resolving the bug and updating documentation accordingly. The work demonstrated depth in API client generation, C# development, and testing, resulting in more robust and developer-friendly code generation for .NET environments.
