Inspect whether the solution has an Aspire AppHost and a MAUI client project.\n2. Use Aspire service discovery when the MAUI app targets .NET 8 or later and\n   the resolved endpoint configuration is actually available to the app at\n   runtime.\n3. Register service discovery and typed `HttpClient` clients in `MauiProgram.cs`.\n4. Use service names such as `https+http:\u002F\u002Fapiservice` only when the matching\n   `Services__...` configuration is present.\n5. Provide platform-reachable fallback base addresses for emulator, simulator,\n   desktop, and physical-device launches.\n6. Account for emulator\u002Fsimulator networking if bypassing Aspire service\n   discovery.\n7. Keep auth, token handlers, and backend API clients in DI.\n8. Validate from Android emulator, iOS simulator, and physical devices as\n   applicable.\n\n## Service Discovery Pattern\n\nMAUI apps deployed to emulators, simulators, or physical devices are usually not\nchild processes of the Aspire AppHost, so the AppHost cannot automatically\ninject service discovery environment variables into the device app. Service-name\nURIs work only when endpoint configuration is supplied to the MAUI app through\nconfiguration, generated settings, or another explicit launch\u002Fdeploy step.\n\nWhen your dev flow can launch the MAUI project from the AppHost, wire the API\nreference there first and pass endpoint configuration to the app:\n\n```csharp\nvar api = builder.AddProject\u003CProjects.ApiService>(\"apiservice\");\nbuilder.AddProject\u003CProjects.MauiClient>(\"mauiclient\")\n       .WithReference(api);\n```\n\n```csharp\nbuilder.Services.AddServiceDiscovery();\n\nbuilder.Services.AddHttpClient\u003CWeatherApiClient>(client =>\n{\n    \u002F\u002F Development only: use \"https:\u002F\u002F\" for production endpoints.\n    client.BaseAddress = new Uri(\"https+http:\u002F\u002Fapiservice\");\n})\n.AddServiceDiscovery();\n```\n\nFor many clients, configure defaults once:\n\n```csharp\nbuilder.Services.ConfigureHttpClientDefaults(http =>\n{\n    http.AddServiceDiscovery();\n});\n```\n\nThe `https+http` scheme expresses HTTPS preference with HTTP fallback according\nto the service discovery scheme rules. It can silently downgrade to HTTP when\nonly HTTP is available, so reserve it for development environments where that is\nacceptable. Use `https:\u002F\u002F` exclusively for production endpoints carrying tokens\nor business data.\n\n## Standalone and Device Fallbacks\n\nFor most mobile device and emulator runs, provide explicit environment\nconfiguration:\n\n| Runtime | Fallback guidance |\n| --- | --- |\n| Android emulator | Use `10.0.2.2` for a host-machine API when not using Aspire service discovery. |\n| iOS simulator | `localhost` usually resolves to the Mac host. |\n| Desktop targets | `localhost` resolves to the same machine. |\n| Physical devices | Use a LAN hostname\u002FIP, dev tunnel, reverse proxy, or deployed endpoint. |\n\nDo not hard-code emulator-only addresses into production configuration.\n\n## Dev Certificates and Cleartext\n\n- Prefer HTTPS with trusted development certificates.\n- If HTTP is needed for local development, add debug-only cleartext exceptions.\n- Prefer installing\u002Ftrusting the development certificate or using an explicit\n  debug-only HTTP fallback over certificate-validation bypass code. Do not show\n  `DangerousAcceptAnyServerCertificateValidator` snippets in generated app\n  guidance.\n- Document how the app is launched under AppHost versus direct device deploy.\n- Avoid disabling certificate validation globally in production code.\n\n## Authentication\n\n- Reuse the app's auth service and typed `HttpClient` handler to attach tokens.\n- Keep OAuth redirect URIs platform-specific; Aspire service discovery does not\n  replace native auth callback setup.\n- For local auth services, ensure emulator\u002Fsimulator redirect and callback URLs\n  match the identity provider configuration.\n\n## Validation Checklist\n\n- The MAUI app registers service discovery or generated service defaults.\n- Typed clients use Aspire service names when launched under AppHost.\n- Standalone fallback addresses are platform-aware and not production defaults.\n- HTTPS\u002Fdev certificate or debug-only cleartext behavior is explicit.\n- Auth and API clients are wired through DI rather than page-level code.\n",{"data":47,"body":48},{"name":4,"description":6},{"type":49,"children":50},"root",[51,59,65,72,150,156,161,166,206,283,288,326,347,353,358,457,462,468,505,511,536,542,570],{"type":52,"tag":53,"props":54,"children":55},"element","h1",{"id":4},[56],{"type":57,"value":58},"text","MAUI
