## Overview

This repository is a set of Azure Durable Functions examples, rather than one unified application. Its workflows accept requests or telemetry, coordinate durable orchestration/entity state, and produce records, notifications, invoices, or monitoring results. The graph preserves the distinct device, fan-out, order, human-approval, and weather-monitoring examples. Shown edges come from excerpts or the source index; dashed edges mark relationships whose implementation was not sampled.

Main entry points: [`DurableFunctions/Entities/TemperatureDevice/TemperatureDeviceEntity.cs`](https://github.com/massimobonanni/azuredurablefunctionssuccinctly/blob/main/DurableFunctions/Entities/TemperatureDevice/TemperatureDeviceEntity.cs) (Temperature entity), [`DurableFunctions/FunctionChaining/FunctionChainingFunctions.cs`](https://github.com/massimobonanni/azuredurablefunctionssuccinctly/blob/main/DurableFunctions/FunctionChaining/FunctionChainingFunctions.cs) (Order functions), [`DurableFunctions/HumanInteraction/HumanInteractionFunctions.cs`](https://github.com/massimobonanni/azuredurablefunctionssuccinctly/blob/main/DurableFunctions/HumanInteraction/HumanInteractionFunctions.cs) (Vacation functions), [`DurableFunctions/Entities/DevicesManagement.cs`](https://github.com/massimobonanni/azuredurablefunctionssuccinctly/blob/main/DurableFunctions/Entities/DevicesManagement.cs) (Device management)
