Worked on upgrading the Edge Configuration Manager API within the Azure/azure-rest-api-specs repository, focusing on aligning the API with the latest RPSaaSMaster Swagger specifications and introducing new preview versions. Enhanced configuration templates and hierarchies to support more scalable and maintainable configuration management, addressing configuration drift and improving compatibility for downstream developers. Updated documentation and README files to reflect these changes, ensuring clarity for future contributors. Performed code maintenance by removing unnecessary imports, refreshing suppression rules, and reverting configuration files as needed. Utilized TypeScript, API development practices, and the Azure SDK to deliver a robust and developer-friendly solution.
