Worked on the dotnet/sdk repository to deliver telemetry enhancements focused on build and target framework evaluation. Developed new telemetry properties to capture target platform identifiers, runtime usage, and publishing options, improving observability for framework support decisions. Incorporated build configuration data into telemetry payloads and introduced a helper for generating structured JSON using C# and XML. Expanded unit tests to ensure coverage of the new telemetry features and their integration with build systems and mobile development workflows. The work addressed the need for more granular telemetry, enabling better analysis of build and framework usage patterns without introducing any bug fixes during the period.
