Developed enhancements to the dotnet/sdk repository by implementing a configurable NuGet push workflow, introducing a --configfile option to the dotnet nuget push command. This addition allows users to specify custom NuGet configuration files, supporting reproducible builds and environment-specific settings. Updated the command parser and completion suggestions in C#, and ensured comprehensive documentation in Markdown within the dotnet/docs repository to reflect the new feature and its precedence over default configurations. Focused on CLI development and NuGet integration, this work improved developer productivity, CI/CD reliability, and cross-repository consistency without addressing major bugs during the one-month contribution period.
