Comet Go — Single-File App Development

Comet Go is a single-file app experience for .NET MAUI using the Comet MVU framework. The user writes ONE .cs file, runs maui go, and it live-reloads on their device.

How It Works

1. User writes a single .cs file with a MainPage : View class
2. maui go starts GoDevServer → Roslyn compiles to DLL (OutputKind.DynamicallyLinkedLibrary)
3. DLL is sent over WebSocket to the companion app
4. Companion app loads via Assembly.Load → MetadataUpdater.ApplyUpdate for hot reload
5. Scaffold new apps with: maui go create <AppName>

Required Imports

Every Comet Go file MUST start with:

#:package Comet
