What it does
Build, test, and maintain the Uno DevServer (CLI tool, RemoteControl Host, MCP proxy, add-in discovery). Use when working under src/Uno.UI.DevServer.Cli, src/Uno.UI.RemoteControl.Host, or src/Uno.UI.RemoteControl.DevServer.Tests, or on DevServer CLI commands, the MCP proxy, IDE channel, or add-in resolution.
DevServer (CLI / Host / MCP)
Maintain and extend the Uno DevServer: the CLI tool, the Host process, MCP proxy integration, and add-in discovery. The DevServer projects are independent of the UI framework and do not require crosstargeting_override.props.
1. Architecture, a 2-process chain
- CLI (
Uno.UI.DevServer.Cli), entry point, user-facing commands, MCP STDIO proxy, start-lifecycle management. - Host (
Uno.UI.RemoteControl.Host), ASP.NET Core server for Hot Reload, IDE channel, processors.
The CLI start command handles existing-server detection (AmbientRegistry), IDE channel rebinding, port allocation, and launches the Host in direct mode (no --command), so all arguments (including --ideChannel) reach the Host via IConfiguration regardless of Host binary version. Non-start commands (stop, list, cleanup) use the Host's controller mode (--command=<verb>). The CLI can also run in MCP mode (--mcp-app) as a Model Context Protocol proxy between AI agents and the running Host.
