Diagnoses and fixes .NET MAUI development environment issues. Validates .NET SDK, workloads, Java JDK, Android SDK, Xcode, and Windows SDK. All version requirements discovered dynamically from NuGet WorkloadDependencies.json — never hardcoded. Use when: setting up MAUI development, build errors mentioning SDK/workload/JDK/Android, "Android SDK not found", "Java version" errors, "Xcode not found", environment verification after updates, or any MAUI toolchain issues. Do not use for: non-MAUI…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# .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issues (Visual Studio or VS Code configuration) ## Important: .NET Version Currency Your training data may be outdated regarding .NET versions. .NET ships new major releases annually (November). Always check the releases-index.json (Task 2) to discover the **latest active major release** — do not assume your training data reflects the current version. For example, if you know about .NET 9.0 but the releases index shows .NET 10.0 as active, use .NET 10.0. ## Inputs …

How to install
mdr add dotnet/skills/dotnet-maui-doctor@sha256:ba8262439bdbc8d9The line at the top of this page pins the label git:20260421.05aeb65, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
