Design Patterns

Pattern Implementation
MVVM ViewModels contain all logic; Views only handle UI binding and events
Observable Pattern ObservableObject base class with INotifyPropertyChanged for reactive UI
Command Pattern RelayCommand and AsyncRelayCommand for button bindings
Service Layer Static service classes encapsulate all data access
Async/Await All I/O-bound and CPU-bound operations are async with Task.Run
Parallel Loading Task.WhenAll loads all sections simultaneously for fast refresh
Auto-load Pages load data on Loaded event (configurable via Settings)

⚙️ Configuration

Running as Administrator

Some features require elevated privileges for full data:

Feature Without Admin With Admin
CPU, GPU, Drives ✅ Full ✅ Full
RAM ✅ Full ✅ Full
GPU VRAM (>4 GB) ✅ Full (registry) ✅ Full
S.M.A.R.T. Disk Health ⚠️ Basic info only ✅ Full S.M.A.R.T. data
Monitor EDID ✅ Full ✅ Full
Network IP/Adapters ✅ Full ✅ Full
Ping, DNS, Traceroute ✅ Full ✅ Full
Performance Counters ⚠️ May be limited ✅ Full
Event Logs ⚠️ May be limited ✅ Full
Firewall Status ❌ Access denied ✅ Full

To run as administrator:

Start-Process .\SystemReview.exe -Verb RunAs

Customizing Network Services List

The monitored network services are defined in Services/DiagnosticsService.cs. You can modify the networkServices array:

string[] networkServices = [
    "Dhcp", "Dnscache", "LanmanServer", "LanmanWorkstation",
    "Netlogon", "NlaSvc", "WlanSvc", "Netman", "RemoteAccess",
    "SharedAccess", "iphlpsvc", "Winmgmt", "W32Time",
    "WinHttpAutoProxySvc", "dot3svc", "SSDPSRV", "upnphost"
];

❓ Troubleshooting

Common Issues

"Side-by-side configuration is incorrect"

The Windows App SDK Runtime is not installed or doesn't match the build version.

Fix:

winget install -e --id Microsoft.WindowsAppRuntime.1.6

Or use a self-contained build:

dotnet publish SystemReview.csproj -c Release -r win-x64 --self-contained true
"Access Denied" errors for WMI or Event Logs

Run the application as Administrator:

Start-Process .\SystemReview.exe -Verb RunAs
S.M.A.R.T. data shows "N/A (run as Admin)"

The S.M.A.R.T. WMI classes (MSStorageDriver_ATAPISmartData) require administrator privileges. Run the app as admin to see power-on hours, temperature, and sector health.

GPU VRAM shows 4 GB instead of actual amount

This was fixed in v1.2.0. The app now reads VRAM from the Windows registry (qwMemorySize) which supports values >4 GB. If you still see incorrect values, ensure you're running the latest version.

Monitor Info tab shows no data

Some monitors don't expose EDID data through WMI. The app has multiple fallbacks:

  1. Raw EDID blocks (WmiMonitorRawEEdidV1Block)
  2. Monitor ID (WmiMonitorID) — manufacturer, serial, name
  3. Desktop Monitor (Win32_DesktopMonitor) — basic info

If none work, your monitor's driver may not support WMI queries.

Battery section shows "No battery detected"

This is normal for desktop PCs. The battery card only shows data on laptops/tablets with a battery.

Performance counters show errors

Performance counters may need to be rebuilt:

# Run as Administrator
lodctr /R

Then restart the app.

NETSDK1206 warning during build

This warning appears when using .NET 10 SDK. It's harmless and doesn't affect functionality. Adding <WindowsAppSDKSelfContained>true</WindowsAppSDKSelfContained> to the .csproj resolves the underlying native DLL copying issue.

XAML editor shows red squiggles in VS Code

This is normal — the XAML IntelliSense in VS Code doesn't fully support WinUI 3 data binding expressions. If dotnet build succeeds, the app is fine. These are design-time warnings only.

⚠️ Known Limitations

Limitation Reason Workaround
NVMe S.M.A.R.T. Some NVMe drives don't expose data via MSStorageDriver_ATAPISmartData Use manufacturer's tool (Samsung Magician, etc.)
Monitor EDID Some monitors/drivers don't expose raw EDID via WMI App falls back to WmiMonitorID
WiFi network scanning WinUI 3 unpackaged apps can't access WiFiAdapter Use netsh wlan show networks manually
Single architecture Self-contained builds target one architecture Build separately for x64 and ARM64
Windows only WMI, PerformanceCounter, and WinUI 3 are Windows-specific No cross-platform support planned
Export to Desktop only Hardcoded export path Modify ExportAsync methods for custom paths
