Microsoft Agent Framework Durable Extension

This repository contains the Durable Task extensions for Microsoft Agent Framework across .NET and Python.

The migrated code covers:

• .NET durable agents and durable workflows for console apps.
• .NET Azure Functions hosting for durable agents and workflows.
• Python Durable Task integration for Microsoft Agent Framework.
• Unit and integration tests, samples, package build metadata, and CI workflows for the Durable extension.

For the full Agent Framework source, see microsoft/agent-framework.

Dependencies

Non-Durable Agent Framework components are consumed as published packages instead of local project references.

• .NET uses NuGet packages such as Microsoft.Agents.AI, Microsoft.Agents.AI.Workflows, and Microsoft.Agents.AI.OpenAI.
• Python uses PyPI packages such as agent-framework-core, agent-framework-foundry, and agent-framework-openai.

Build and test

.NET

Set-Location dotnet
dotnet restore .\agent-framework-durable-extension.slnx
dotnet build .\agent-framework-durable-extension.slnx --configuration Release --no-restore
dotnet test --project .\tests\Microsoft.Agents.AI.DurableTask.UnitTests\Microsoft.Agents.AI.DurableTask.UnitTests.csproj --configuration Release --no-build
dotnet test --project .\tests\Microsoft.Agents.AI.Hosting.AzureFunctions.UnitTests\Microsoft.Agents.AI.Hosting.AzureFunctions.UnitTests.csproj --configuration Release --no-build

Package artifacts:

dotnet pack .\src\Microsoft.Agents.AI.DurableTask\Microsoft.Agents.AI.DurableTask.csproj --configuration Release --output .\artifacts\packages
dotnet pack .\src\Microsoft.Agents.AI.Hosting.AzureFunctions\Microsoft.Agents.AI.Hosting.AzureFunctions.csproj --configuration Release --output .\artifacts\packages

Python

Set-Location python
uv sync --all-packages --group dev --group test
uv run pytest -m "not integration" packages\durabletask\tests
uv build packages\durabletask --out-dir dist

Integration tests

Integration tests require local infrastructure:

• Durable Task Scheduler emulator
• Azurite
• Redis
• Azure Functions Core Tools for Azure Functions samples/tests
• Foundry environment variables for model-backed tests

Common environment variables:

DURABLE_TASK_SCHEDULER_CONNECTION_STRING=Endpoint=http://localhost:8080;TaskHub=default;Authentication=None
AzureWebJobsStorage=UseDevelopmentStorage=true
REDIS_CONNECTION_STRING=redis://localhost:6379
FOUNDRY_PROJECT_ENDPOINT=<foundry-project-endpoint>
FOUNDRY_MODEL=<foundry-model>

The .github/actions/azure-functions-integration-setup action starts the emulator dependencies in CI.

Samples

• .NET Durable Agents: dotnet\samples\DurableAgents
• .NET Durable Workflows: dotnet\samples\DurableWorkflows
• Python Durable Task samples: python\samples

Python samples are copied directly under python\samples; there is no redundant durabletask path segment.
