Azure Durable Functions for serverless .NET orchestration
summary
Durable orchestration runs on Azure Durable Functions as an open-source Azure Functions extension that uses event sourcing and an execution history in Azure Storage (tables and queues) to resume work, scale to zero, and guarantee at-least-once execution. Demo shows local Visual Studio + Storage Emulator, an orchestration calling three activities (hello Tokyo/Seattle/London), and a report generator that fans out to call shipping APIs for thousands of orders, returns status endpoints, and logs to Application Insights. Orchestrator code must be deterministic (use provided time helpers), do I/O in activities, and use continueAsNew to avoid unbounded replay.
