There's like... zero momentum behind MAUI. The wider industry has learned their lesson and nobody in their right mind would ever use MAUI for a new GUI project unless Microsoft converts 80% of their applications to it.

The only decent GUI framework for Windows is Electron, which is based on Chromium.

Microsoft's new GUI applications use Electron: VS Code, Azure Data Studio, etc...

In other words: Google makes the best Microsoft Windows GUI framework, as endorsed by Microsoft's own developers.
