AI-powered assistance for upgrading and modernizing .NET applications. This plugin adds the modernize-dotnet agent to your Copilot CLI.

Add the marketplace, then install the plugin:

/plugin marketplace add dotnet/modernize-dotnet
/plugin install modernize-dotnet@modernize-dotnet-plugins

Use /agent to select modernize-dotnet, then enter your prompt:

upgrade my project to .NET 10

The agent guides you through a structured workflow:

1. Assessment — analyzes your project and identifies what needs to change
2. Planning — creates a step-by-step upgrade plan
3. Execution — applies the changes using specialized tools

The plugin includes an MCP server (Modernization) that provides upgrade and analysis tools. It starts automatically when the modernize-dotnet agent is invoked — no manual configuration needed.
