Get Connected Monitors Report (C#)

// GetDesktopMonitorReport.cs
//
// Reports Connected Monitors via WMI (Win32_DesktopMonitor).
//
// Requires the System.Management package:
//   dotnet new console -o DesktopMonitorReport
//   dotnet add package System.Management
//   (replace the generated Program.cs with this file, then dotnet run)
// On .NET Framework, System.Management is already available — just
// add a reference to it in your project.
