PolyPilot hints at a future where the tool a developer is running is also the tool they are editing, with Copilot standing by to patch the live codebase and relaunch the experience instantly. Today, .NET MAUI largely hides behind NuGet packages; developers consume binaries, report bugs, and wait for maintainers to publish fixes. Flutter, conversely, places the framework and engine sources on every machine, inviting developers to debug, instrument, and modify the stack. This proposal imagines .NET MAUI adopting a similar source-first distribution and pairing it with Copilot-powered contribution gestures so every MAUI developer can become a potential framework contributor while building their app.
A source-first MAUI workspace would clone the framework next to every app, exposing src/Core, src/Controls, platform handlers, and native bindings. Developers could set brea
