Modernizing a Legacy .NET App with GitHub Copilot
GitHub Copilot now automates end-to-end .NET legacy modernization with security scanning built in
“we're taking the security suggestions and interjecting that so that when we upgrade, we're not also introducing more vulnerabilities”
Microsoft demonstrated a GitHub Copilot agent skill that automates modernizing legacy .NET Framework apps to .NET 10, covering assessment, security baseline, migration planning, and database upgrades. The tool integrates open-source community prompts and VS Code extensions to handle brownfield enterprise applications without requiring MCP. While technically interesting for enterprise dev tooling, this is a developer productivity demo rather than a core AI industry signal.
