Worked on the Azure/azure-functions-durable-extension repository to refactor the CustomTestStorageAccountProvider, focusing on improving test reliability and maintainability. The update replaced direct CloudStorageAccount usage with IStorageServiceClientProviderFactory-backed providers for Blobs, Queues, and Tables, aligning the codebase with newer Azure SDK patterns. This change streamlined the provisioning of storage clients in unit tests, reducing technical debt and making future updates easier to manage. The work leveraged C# and Azure Storage, with an emphasis on refactoring and unit testing practices. No bugs were fixed during this period, as the primary focus was on delivering this targeted feature enhancement.
