This is the GitHub Copilot Chat extension for Visual Studio Code - a VS Code extension that provides conversational AI assistance, a coding agent with many tools, inline editing capabilities, and advanced AI-powered features for VS Code. Choose validation based on the scope and risk of the change. Prefer existing diagnostics and the smallest targeted tests that cover the changed behavior. Do not start start-watch-tasks, run a full build, or make type checking a prerequisite for targeted tests solely as…
Visual Studio Code is built with a layered architecture using TypeScript, web APIs and Electron, combining web technologies with native app capabilities. The codebase is organized into key architectural layers: The core architecture follows these principles: - Layered architecture - from base, platform, editor, to workbench - Dependency injection - Services are injected through constructor parameters - If non-service parameters are needed, they need to come before the service parameters - Contribution model - Features contribute to registries and extension…
Concise guidance for AI-assisted development of this Command Palette extension. If using git, remove these lines from .gitignore (needed for deployment): - **/Properties/launchSettings.json - *.pubxml This project includes Copilot skills for common workflows: - add-adaptive-card-form — Create form-based UI with Adaptive Cards - add-extension-settings — Add a settings page to your extension - add-dock-band — Add persistent toolbar widgets - add-fallback-commands — Add catch-all search commands - publish-extension — Publish to Microsoft Store or WinGet
This repository contains the native TypeScript compiler and language server. The source directories of interest that we have are: Most compiler development takes place in tsc/internal, and most behaviors can be tested via compiler tests. Most development on the codebase is in Go. Standard Go commands and practices apply, but we primarily use a tool called hereby to build, run tests, and other tasks. Run npx hereby --tasks to see all available commands. Always make sure code is formatted, linted,…
AutoGen is a multi-language framework for creating AI agents that can act autonomously or work alongside humans. The project has separate Python and .NET implementations with their own development workflows.
ALWAYS reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here. WSL is the Windows Subsystem for Linux - a compatibility layer for running Linux binary executables natively on Windows. This repository contains the core Windows components that enable WSL functionality. Use WIL (Windows Implementation Libraries) macros — never bare if (FAILED(hr)): - THROWIFFAILED(hr) — throw on HRESULT failure - THROWHRIF(hr, condition) — conditional throw -…
This is the Windows Package Manager (WinGet) CLI client - a native Windows application for discovering and installing packages. The codebase consists of: Use a configuration file in .config as in winget configure .config/configuration.winget (alternatives provided for other VS SKUs). Manual steps: Open src\AppInstallerCLI.sln in Visual Studio and build the solution (Ctrl+Shift+B) or use msbuild.exe to build from the command line. The solution uses: - MSBuild - vcpkg for C++ dependencies - NuGet for C++ and .NET dependencies Entry point:…
This file provides guidance to GitHub Copilot for contributing to the React Native Windows repository. React Native Windows brings React Native to the Windows platform, supporting both UWP and Win32…
Pyright is a static type checker for Python, written in TypeScript. It ships as an npm CLI (pyright), an LSP language server (pyright-langserver), and a VS Code extension (vscode-pyright). Source…
Microsoft Agent Framework - a multi-language framework for building, orchestrating, and deploying AI agents. ADRs in docs/decisions/ capture significant design decisions and their rationale. They document considered alternatives, trade-offs, and the reasoning behind choices. Templates: - adr-template.md - Full template with detailed sections - adr-short-template.md - Abbreviated template for simpler decisions When proposing architectural changes, create an ADR to capture options considered and the decision rationale. See docs/decisions/README.md for the full process.
Read this file at the start of every session. It contains the essential commands, conventions, and architecture knowledge needed to work on this repository. Do not create git commits automatically. The maintainer reviews all changes first and handles commits manually. Make changes locally, run fmt/clippy/tests to verify, and report back. Cargo workspace (resolver = "3"). Members are globbed from: - crates/libs/* - the published/library crates (windows, windows-sys, windows-core, plus windows-bindgen, metadata, rdl, and the newer reactor/canvas/webview/window crates). See docs/readme.md for…
Garnet is a high-performance remote cache-store from Microsoft Research implementing the Redis RESP wire protocol in C#/.NET. It uses Tsavorite as its storage engine. Full developer docs: https://microsoft.github.io/garnet/docs/dev/onboarding Note: Some website docs may reference the older two-store architecture (separate main store and object store). This branch uses a unified single-store design — see the Architecture section below for the current model. GARNETTESTPORT_SLOT=auto keeps this working copy's test ports clear of other working copies on the same machine; see Running tests…
This is the Windows Package Manager (WinGet) community repository — a manifest-only repo containing ~415,000+ YAML files describing how to install Windows applications via winget. There is no application source code here. The tooling is PowerShell scripts in Tools/. Never recursively scan or search the manifests/ directory. It contains hundreds of thousands of files and will cause severe performance issues. Only search within the specific package folder being modified (e.g., manifests/m/Microsoft/WindowsTerminal/). Each package version lives in manifests/<first-letter>/<Publisher>/<Package>/<Version>/ and requires three…
