GitHub Copilot upgrade

Upgrade your projects with GitHub Copilot. This is the shippable VS Code extension (ms-dotnettools.upgrade-agent) for the GitHub Copilot upgrade family. It hosts the orchestrator and self-bundles the first-party .NET upgrade extender, so a single install covers .NET upgrades and migrations end-to-end.

Third-party language extenders ship as their own VS Code extensions and are discovered automatically when installed alongside this one.

What this extension does

• Acquires the .NET SDK runtime required by the upgrade MCP server (Microsoft.GitHubCopilot.Upgrade.Mcp).
• Registers the Upgrade MCP server with VS Code — the single MCP surface every upgrade tool flows through.
• Bundles the first-party .NET extender (under extenders/dotnet/) and discovers any additional VS Code extensions that contribute upgradeExtensions (the extender contribution model documented in doc/modernization-agent/vscode-extensibility.md), exposing them to the orchestrator MCP via host-extenders.json.
• Hosts the upgrade.agent chat participant and ships the bundled agent prompt.
