Durable Functions) is the official +Azure Functions extension that enables writing stateful, long-running workflows as code. +It provides orchestrator functions, activity functions, and entity functions on top of +the Durable Task Framework. + +This repo contains two main extension packages: + +| Package | NuGet | Description | +|---|---|---| +| `Microsoft.Azure.WebJobs.Extensions.DurableTask` | In-process (.NET) | Classic WebJobs-based extension for Azure Functions v1–v4 in-process | +| `Microsoft.Azure.Functions.Worker.Extensions.DurableTask` | Isolated (.NET worker) | Extension for the .NET isolated worker model | + +It also includes a **Roslyn analyzer** package that detects common Durable Functions +coding mistakes at compile time. + +**This is NOT the standalone Durable Task SDK.** That lives in separate repos +(`durabletask-dotnet`, `durabletask-js`, etc.). This extension *consumes* the +Durable Task Framework and adds Azure Functions trigger bindings, middleware, and +Azure Storage / Netherite / MSSQL backend integration. + +--- + +## Core Execution Model — Replay-Based Orchestrations + +### How Orchestrations Work + +Orchestrator functions are replayed from history to rebuild state. The extension manages +the replay loop, event sourcing, and communication with the chosen storage backend +(Azure Storage, Netherite, or MSSQL). + +On every re-invocation: +1. The orchestrator function receives its `IDurableOrchestrationContext`. +2. Completed tasks resolve instantly from history (replay). +3. Incomplete tasks suspend the orchestrator until the next event arrives. +4. New actions are written to the storage backend. + +### The Determinism Rule (Critical) + +**Orchestrator code MUST be deterministic.** Every replay must produce the exact same +sequence of actions. Violations cause `NonDeterministicOrchestrationException`. + +What this means in practice: +- **No `DateTime.Now`** — use `context.CurrentUtcDateTime` +- **No `Guid.NewGuid()`** — use `context.NewGuid()` +- **No direct I/O** (HTTP calls, file reads, database queries) — use activities +- **No `Task.Delay`** — use `context.CreateTimer()` +- **No thread-unsafe or environment-dependent operations** + +### Activities vs Orchestrations + +Activities execute side effects exactly once (modulo retries) and persist results +as history events. They can do anything: HTTP calls, DB writes, etc. + +**Key mental model:** Orchestrations = coordination logic (deterministic). +Activities = real work (non-deterministic allowed). + +### Entities + +Durable Entities provide stateful, actor-like programming. They process operations +sequentially and can be signaled or called from orchestrations or clients. + +--- + +## Architecture — How Pieces Connect + +### In-Process Extension (`WebJobs.Extensions.DurableTask`) + +The in-process extension hooks into the Azure Functions WebJobs SDK: +- `DurableTaskExtension` — the main extension entry point (implements `IExtensionConfigProvider`) +- `DurableOrchestrationContext` — wraps the Durable Task Framework's orchestration context +- `DurableActivityContext` / `DurableEntityContext` — similar wrappers for activities/entities +- Trigger bindings: `OrchestrationTriggerAttribute`, `ActivityTriggerAttribute`, `EntityTriggerAttribute` +- Client bindings: `DurableClientAttribute` + +### Isolated Worker Extension (`Worker.Extensions.DurableTask`) + +The isolated worker extension uses gRPC to communicate between the Functions host +and the worker process: +- `DurableTaskFunctionsMiddleware` — middleware for the isolated worker +- Protobuf messages for cross-process orchestration replay +- Client, orchestration, and entity abstractions that proxy through gRPC + +### Storage Backends + +The extension supports multiple storage providers: +- **Azure Storage** (default) — uses Azure Table Storage, Blob Storage, and Queue Storage +- **Netherite** — high-performance backend using Event Hubs and FASTER +- **MSSQL** — Microsoft SQL Server backend + +### Roslyn Analyzers + +The analyzer package (`WebJobs.Extensions.DurableTask.Analyzers`) provides compile-time +checks for common mistakes: +- Non-deterministic API usage in orchestrators +- Incorrect binding attribute usage +- Invalid orchestrator patterns + +--- + +## Project Structure + +``` +src/ + WebJobs.Extensions.DurableTask/ # In-process extension + Worker.Extensions.DurableTask/ # Isolated worker extension + WebJobs.Extensions.DurableTask.Analyzers/# Roslyn analyzers + DurableFunctions.TypedInterfaces/ # Code-gen for typed interfaces + +test/ + FunctionsV1/ # Tests targeting Functions v1 + FunctionsV2/ # Tests targeting Functions v2+ (main test project) + Common/ # Shared test code + Worker.Extensions.DurableTask.Tests/ # Worker extension unit tests + WebJobs.Extensions.DurableTask.Analyzers.Test/ # Analyzer tests + e2e/ # End-to-end test apps + SmokeTests/ # Smoke tests for various runtimes + DFPerfScenarios/ # Performance test scenarios + +samples/ # Sample applications + +docs/ # Documentation +``` + +--- + +## Build and Test + +### Building + +```bash +dotnet restore WebJobs.Extensions.DurableTask.sln +dotnet build WebJobs.Extensions.DurableTask.sln +``` + +### Running Tests + +Tests require **Azurite** (Azure Storage emulator) running on ports 10000/10001/10002: + +```bash +# Start Azurite (or use npm: npx azurite) +docker run -d -p 10000:10000 -p 10001:10001 -p 10002:10002 \ + mcr.microsoft.com/azure-storage/azurite + +# Run in-process extension tests (excluding E2E) +dotnet test ./test/FunctionsV2/WebJobs.Extensions.DurableTask.Tests.V2.csproj \ + --filter "FullyQualifiedName!~DurableTaskEndToEndTests" + +# Run worker extension tests +dotnet test ./test/Worker.Extensions.DurableTask.Tests/Worker.Extensions.DurableTask.Tests.csproj + +# Run analyzer tests +dotnet test ./test/WebJobs.Extensions.DurableTask.Analyzers.Test/WebJobs.Extensions.DurableTask.Analyzers.Test.csproj +``` + +--- + +## Error Handling Patterns + +| Error | When | +|---|---| +| `FunctionFailedException` | Activity or sub-orchestration fails | +| `NonDeterministicOrchestrationException` | Replayed action mismatches history | +| `TimeoutException` | Durable timer exceeds timeout | +| `TaskFailedException` | Activity throws during execution | + +--- + +## Code Conventions + +### C# Style +- Top of all `.cs` files: Microsoft copyright header + MIT license reference +- All public methods and classes must have XML documentation comments +- Use `this.` for accessing class members +- Use `Async` suffix on async method names +- Private classes that don't serve as base classes must be `sealed` +- StyleCop analyzers enforce formatting rules + +### Testing +- Framework: **xUnit** with **Moq** for mocking +- Test projects use shared code from `test/Common/` +- E2E tests are separate from unit tests and may require live Azure resources + +### Branching +- **`dev`** — default branch;
