Do not run it automatically.\n\n## Prerequisites\n\n- The `maui` CLI tool installed (`dotnet tool install -g Microsoft.Maui.Cli`)\n- A .NET MAUI app with `Microsoft.Maui.DevFlow.Agent` NuGet package added\n- The app must be running on a target device or emulator\n\n## Workflow\n\n### 1. Verify Agent Integration\n\nConfirm the app has the DevFlow agent NuGet package:\n\n```bash\ngrep -r \"Microsoft.Maui.DevFlow.Agent\" *.csproj\n```\n\nThe agent must be initialized in `MauiProgram.cs`:\n\n```csharp\nbuilder.Services.AddMauiDevFlowAgent();\n```\n\n### 2. Check Broker Status\n\n```bash\nmaui devflow broker status\n```\n\nIf the broker is not running, start it:\n\n```bash\nmaui devflow broker start\n```\n\n### 3. Platform-Specific Connectivity\n\n#### Android Emulator\n\nAndroid emulators run in a network namespace. Port forwarding is required:\n\n```bash\nadb reverse tcp:19223 tcp:19223  # Broker port\nadb reverse tcp:9223 tcp:9223    # Agent default port\n```\n\nVerify with:\n\n```bash\nadb reverse --list\n```\n\n#### iOS Simulator\n\nNo port forwarding needed — simulators share the host network. Verify the app is running:\n\n```bash\nxcrun simctl list devices booted\n```\n\n#### Mac Catalyst \u002F macOS\n\nDirect localhost access. Check if the port is in use:\n\n```bash\nlsof -i :9223\n```\n\n#### Windows\n\nDirect localhost access. Check firewall rules if connection fails.\n\n#### Linux (GTK)\n\nDirect localhost access. Verify the app process is running:\n\n```bash\npgrep -f \"YourApp\"\n```\n\n### 4. List Connected Agents\n\n```bash\nmaui devflow list\n```\n\nExpected output shows agent ID, app name, platform, and port. If empty, the agent in the app is not reaching the broker.\n\n### 5. Test Connection\n\n```bash\nmaui devflow tree --depth 1\n```\n\nA successful response returns the top-level visual tree. If this fails with a timeout, the agent HTTP server inside the app may not be responding.\n\n### 6. Common Fixes\n\n| Symptom | Fix |\n|---------|-----|\n| No agents listed | Check agent NuGet package + `AddMauiDevFlowAgent()` call |\n| Android: connection refused | Run `adb reverse` for both ports (19223 + 9223) |\n| Port already in use | Kill stale process: `lsof -i :9223` then `kill \u003CPID>` |\n| Broker not running | `maui devflow broker start` |\n| App crashes on startup | Check that DevFlow agent version matches MAUI version |\n",{"data":45,"body":46},{"name":4,"description":6},{"type":47,"children":48},"root",[49,57,71,78,120,126,157,163,176,182,223,229,236,241,296,309,325,331,360,365,392,398,405,410,471,476,499,505,510,545,551,556,581,587,592,598,603,637,643,666,671,677,711,716,722,849],{"type":50,"tag":51,"props":52,"children":53},"element","h1",{"id":4},[54],{"type":55,"value":56},"text","DevFlow Connect",{"type":50,"tag":58,"props":59,"children":60},"p",{},[61,63,69],{"type":55,"value":62},"Diagnose and resolve connectivity between the ",{"type":50,"tag":64,"props":65,"children":67},"code",{"className":66},[],[68],{"type":55,"value":18},{"type":55,"value":70}," CLI and running .NET MAUI apps instrumented with the DevFlow agent.",{"type":50,"tag":72,"props":73,"children":75},"h2",{"id":74},"when-to-use",[76],{"type":55,"value":77},"When to Use",{"type":50,"tag":79,"props":80,"children":81},"ul",{},[82,94,105,110,115],{"type":50,"tag":83,"props":84,"children":85},"li",{},[86,92],{"type":50,"tag":64,"props":87,"children":89},{"className":88},[],[90],{"type":55,"value":91},"maui devflow list",{"type":55,"value":93}," shows no agents",{"type":50,"tag":83,"props":95,"children":96},{},[97,103],{"type":50,"tag":64,"props":98,"children":100},{"className":99},[],[101],{"type":55,"value":102},"maui devflow tree",{"type":55,"value":104}," fails with \"Cannot connect to agent\"",{"type":50,"tag":83,"props":106,"children":107},{},[108],{"type":55,"value":109},"Port conflicts on 9223 or the broker port",{"type":50,"tag":83,"props":111,"children":112},{},[113],{"type":55,"value":114},"Android emulator connectivity issues (adb port forwarding)",{"type":50,"tag":83,"props":116,"children":117},{},[118],{"type":55,"value":119},"App is running but DevFlow commands fail",{"type":50,"tag":72,"props":121,"children":123},{"id":122},"when-not-to-use",[124],{"type":55,"value":125},"When Not to Use",{"type":50,"tag":79,"props":127,"children":128},{},[129,134,147,152],{"type":50,"tag":83,"props":130,"children":131},{},[132],{"type":55,"value":133},"Build or deployment failures (use standard build diagnostics)",{"type":50,"tag":83,"props":135,"children":136},{},[137,139,145],{"type":55,"value":138},"Environment setup (use ",{"type":50,"tag":64,"props":140,"children":142},{"className":141},[],[143],{"type":55,"value":144},"dotnet-maui-doctor",{"type":55,"value":146}," from dotnet\u002Fskills)",{"type":50,"tag":83,"props":148,"children":149},{},[150],{"type":55,"value":151},"Visual tree queries after connection works",{"type":50,"tag":83,"props":153,"children":154},{},[155],{"type":55,"value":156},"CDP\u002FBlazor WebView debugging",{"type":50,"tag":72,"props":158,"children":160},{"id":159},"optional-session-feedback-nudge",[161],{"type":55,"value":162},"Optional Session Feedback Nudge",{"type":50,"tag":58,"props":164,"children":165},{},[166,168,174],{"type":55,"value":167},"If connectivity recovery required repeated broker\u002Flist\u002Fwait\u002Fstatus attempts,\nAndroid forwarding detours, direct port fallback, or other workarounds, ask\nwhether the user wants to run ",{"type":50,"tag":64,"props":169,"children":171},{"className":170},[],[172],{"type":55,"value":173},"maui-devflow-session-review",{"type":55,"value":175}," to summarize friction\nfor MAUI DevFlow product feedback.
