TaskManagerUI

A modern Windows Task Manager-style desktop app built with WinUI 3 and .NET 8.

It provides a clean UI for real-time monitoring of:

• Processes (CPU, memory, disk, network)
• System overview metrics
• GPU activity (dedicated + integrated)
• Live performance charts

Features

• Processes view
  • Hierarchical process list
  • Sort by name, PID, CPU, memory, disk and network metrics
  • Search by process name or PID
  • Kill selected process(es) from UI or with Delete
• Charts view
  • Live charts for CPU, RAM, GPU utilization, GPU memory, GPU temperature, and process count
  • Lightweight local SQLite storage for short history
• GPU view
  • NVIDIA GPU data via nvidia-smi (if available)
  • Integrated GPU process detection via Windows performance counters
• Modern Windows UI
  • WinUI 3 styling with cards, compact navigation, and Mica backdrop support

Tech Stack

• .NET 8
• WinUI 3 / Windows App SDK
• LiveChartsCore + SkiaSharp for charts
• Microsoft.Data.Sqlite for local telemetry snapshots
• ETW (TraceEvent) for process-level network activity

Requirements

• Windows 10/11 (target framework: net8.0-windows10.0.19041.0)
• .NET 8 SDK
• Visual Studio 2022 with Windows development workload

Optional:

• nvidia-smi in PATH for dedicated NVIDIA GPU metrics
• Elevated privileges may improve ETW/network visibility on some systems
• For full GPU metrics, run the app as Administrator

Build & Run

dotnet restore
dotnet build
dotnet run

You can also open TaskManagerUI.csproj in Visual Studio and run it directly.

Project Structure

• MainWindow.xaml / MainWindow.xaml.cs - main UI and interaction logic
• Monitoring/Common.cs - process/system/memory/network collection
• Monitoring/EtwNetworkMonitor.cs - ETW network monitoring per process
• Monitoring/GPU/NvidiaGPU.cs - dedicated + integrated GPU data
• Charts/Databse.cs - SQLite persistence for chart history

Notes

• The app stores chart data in a temporary local database while running.
• GPU features degrade gracefully if hardware/counters/tools are unavailable.
• GPU monitoring may require running the app as Administrator.
