To diagnose .NET MAUI environment issues, run a health check that validates SDKs, JDK (Microsoft OpenJDK), Android SDK, Xcode, and Windows SDK. It detects version mismatches and configuration gaps using live manifest data from NuGet, then provides actionable remediation steps.

Your .NET MAUI build may fail due to version mismatches in JDK, Android SDK, Xcode, or Windows SDK after updates. A post-update verification scan detects these mismatches using dynamic version discovery from NuGet WorkloadDependencies.json and recommends explicit versioned installs to fix the issue.

The best way to validate Xcode and JDK prerequisites for .NET MAUI is to scan your environment against live manifest data from NuGet WorkloadDependencies.json. This process verifies platform toolchains, enforces dynamic version discovery, and guides you through remediation commands until all checks pass.

You can fix .NET MAUI SDK version mismatches and configuration gaps by running a diagnostic health check. It auto-detects missing tools across macOS, Windows, and Linux, recommends explicit versioned installs for remediation, and re-validates your environment until all prerequisite checks pass.

Yes, .NET MAUI diagnostic checks support troubleshooting Microsoft OpenJDK and Android SDK configurations. It validates these platform toolchains during setup and health checks across macOS, Windows, and Linux, detecting version mismatches and providing guided remediation commands to restore your environment.

You need to run a .NET MAUI environment health check when setting up a new workstation, after applying SDK or workload updates, or when troubleshooting build failures that mention missing SDKs or tools. It validates .NET MAUI SDKs, JDK, Android SDK, Xcode, and Windows SDK configurations.
