NET MAUI in VS Code Dev Container on macOS gets stuck on "Android: Analyzing environment...", no launchable projects found, and MAUI task type is not registered

[Franciszekpawlowski]

Type: Bug

In VS Code Dev Containers on macOS host, .NET MAUI for Android never becomes usable.

Symptoms:

• "Android: Analyzing environment..." spins forever
• walkthrough button/action is dead
• F5 does not launch the MAUI app
• startup selector shows only unit tests, not the app
• "No launchable projects found."
• "Debugging canceled: startup project not found."
• if using tasks.json with "type": "maui": "there is no registered task type 'maui'"

The environment appears valid:

• Android SDK path is configured
• Java path is configured
• network/DNS inside container works
• dotnet workload list shows maui-android installed

This looks like a MAUI tooling / detection issue rather than a project misconfiguration.
