💻 WinUI3 - Resource Monitor Utility

• Monitors entire CPU load (among others) and displays the results in a graph using Microcharts.
• This project contains a good collection of native Win32 API calls as well as extension methods, but only a select few are used.
• Other Nuget packages include: Microcharts, SkiaSharp.Views.WinUI, System.Diagnostics.PerformanceCounter and System.Drawing.Common.
• I have added calls to update the taskbar application icon in real-time and demonstrate two ways to do this. One technique uses the Microsoft.UI.Windowing.AppWindow.SetIcon and the other uses the Win32 API SendMessage call by passing the icon handle (requires System.Drawing.Common).
• I recommend keeping this project in an Unpackaged format, as it was meant to be a portable utility.
• About the PerformanceCounters, there are approximately 2 giga-zillion categories and sub-categories, I am only showing four extremely common counters in this utility. One could go mad investigating them all. e.g. there is a multi-instance "SystemRestore" category which contains another instance category named "ServiceModelService" which exposes 35 sub-categories. Your categories may differ from the example due to the version of OS and what features you have enabled/disabled.

🎛️ Usage

• You can run this as a normal desktop app, or by launching the executable or from the command line:
  • C:\>monitor disk 2 -4 695 1925 350 2.5
    • would mean to start a disk usage graph on monitor #2 starting at screen coord -4,695 and a window having a width of 1925 and a height of 350 and an update frequency of 2.5 seconds.
  • C:\>monitor disk 2 -4 695 1925 350 2.5 true
    • same as above but with Acrylic Backdrop enabled.
  • C:\>monitor cpu
    • would mean to start a CPU usage graph using the settings found in Setting.xml.
  • A shortcut could be made in shell:startup with these parameters.
  • All settings are stored in the running folder location under the name Settings.xml

• This application was compiled and tested using VisualStudio 2022 on Windows 10 versions 22H2, 21H2 and 21H1.
• No memory leaks were observed using Microcharts, however memory leaks were observed using OxyPlot. I have created an issue on github concerning the OxyPLot memory leak
