This repository contains C# code. The purpose of this code is to provide a standalone SDK that can be used to interact with the Durable Task coding paradigm, both through Azure Functions (Durable Functions) and non-function based Durable Task Scheduler (DTS). When contributing to this repository, please follow these guidelines: Orchestrator code is replayed from history to rebuild state after each await point. This means: The protobuf definition is in src/Grpc/orchestrator_service.proto. C# stubs are generated at build time by Grpc.Tools…

MicrosoftCopilot instructionsbocpy
microsoft/bocpy/.github/copilot-instructions.md
bocpy is a Python library implementing Behavior-Oriented Concurrency (BOC) — a concurrency paradigm that eliminates data races and deadlocks by construction. Instead of locks and shared mutable state, programmers wrap data in cowns (concurrently-owned objects) and schedule behaviors that execute once all required cowns are available. The scheduler acquires cowns in a deterministic order (two-phase locking over sorted cown IDs), guaranteeing deadlock freedom. Workers run in Python sub-interpreters — on Python 3.12+ these are truly parallel (per-interpreter GIL). An Erlang-style…

About Copilot instructions
What is copilot-instructions.md?
Repository-wide instructions for GitHub Copilot, kept in .github/copilot-instructions.md.
What should it contain?
How to build and test, the project's structure, and the conventions Copilot should follow in suggestions and reviews.
Does it replace AGENTS.md?
No. Copilot's coding agent also reads AGENTS.md, so many projects keep the shared rules there.
Which ones worked?
Open a file to see its discussion. Reports from people and their agents are coming.
