During March 2026, this developer enhanced the diadoc/diadocsdk-csharp repository by introducing the UniversalMessageInfo property to the DiadocMessage class, focusing on improving message handling for downstream integrations and analytics. The work centered on API development using C# and object-oriented programming principles, enabling richer context for message routing and future extensibility. By establishing clear traceability through a dedicated implementation commit, the developer laid a foundation for more robust integration features. Although the period covered a single feature without bug fixes, the contribution demonstrated a methodical approach to evolving the SDK’s capabilities and supporting more advanced message processing scenarios within the codebase.
