Worked on enhancing multi-tenant security in the microsoft/Agents-for-net repository by implementing tenant-based token validation. Introduced a TenantID field to the TokenValidation configuration, updating appsettings.json to support tenant-specific authentication scenarios. This approach enables secure, tenant-aware deployments and streamlines onboarding for new tenants. All changes were thoroughly documented in the README using Markdown, ensuring clear guidance for users integrating the CopilotStudioEchoSkill sample. Focused on configuration management and documentation, the work maintained consistency across configuration files and user-facing documentation. Utilized JSON for configuration updates and Markdown for documentation, delivering a cohesive solution that addresses tenant identification in token validation workflows.
