copilot

The Copilot SDK, now in public preview with support for five languages and bring-your-own-key authentication, exposes the same agent runtime powering GitHub Copilot CLI as a programmable library for building custom AI-driven tools and workflows.

GitHub's new opt-out policy lets it use code snippets, prompts, and context from Free, Pro, and Pro+ users to train AI models, drawing sharp criticism from developers who call it a bait-and-switch.

Microsoft's Visual Studio 2026 ships with AI agents for profiling and debugging, a decoupled build system, 50% faster solution loads, and full backward compatibility — positioning the 30-year-old IDE against Cursor and VS Code in the AI coding era.
