Microsoft opens the Copilot harness behind VS Code and Copilot CLI to Foundry agents, in preview
Announced Oct 28, Foundry Agent Service can now run your agent on the same managed loop and sandbox as GitHub's Copilot products, with skills, MCP tools and 20+ models; you pick it at agent creation and can't switch later. Runtime is free until Dec 1, then $0.0994 per vCPU-hour plus model costs, and the GitHub Copilot SDK is being renamed Microsoft Copilot SDK (changelog).
