[Epic] vibe-coding .NET MAUI apps works out of the box

[jonathanpeppers]

Dream workflow

• I have a blank .NET MAUI template ready, with an IDE open.
• I drop a design (image) into Copilot Chat, and simply say "implement this design".
• The AI iterates: using hot reload, screenshots, logs, visual tree, and gives me something close to the target image.

Example

An example of what we are looking for (WPF example) is:

Implementation

CLI is an initial starting point, as it requires little configuration and "agent mode" copilots can run commands to accomplish tasks. MCP servers are an addition, we will consider where needed.
