.NET MAUI Doctor

Validate and fix .NET MAUI development environments. All version requirements are discovered dynamically from NuGet APIs — never hardcode versions.

When to Use

• Setting up a new .NET MAUI development environment
• Build errors mentioning missing SDKs, workloads, JDK, or Android components
• Errors like "Android SDK not found", "Java version", or "Xcode not found"
• Verifying environment health after SDK or OS updates

When Not to Use

• Non-MAUI .NET projects (use standard .NET SDK troubleshooting instead)
• Xamarin.Forms apps (different toolchain and workload requirements)
• Runtime app crashes unrelated to environment setup
• App store publishing or signing issues
• IDE-specific issues (Visual Studio or VS Code configuration)
