What would be the best way to setup PInvoke.SetConsoleCtrlHandler?

[AY1uZwIcJzKhaGywovQP]

When I try, I get the following error (sanitized):

Severity	Code	Description	Project
Error (active)	CS1503	Argument 1: cannot convert from 'Program.MyClass.ConsoleCtrlDelegate' to 'Windows.Win32.System.Console.PHANDLER_ROUTINE'	Program

My current approach is:

using System;
using System.Runtime.InteropServices;
using Windows.Win32;

class MyClass
{
    // Define the callback delegate
    private delegate bool ConsoleCtrlDelegate(uint ctrlType);

    static void Main(string[] args)
    {
        // Create an instance of the callback delegate
        ConsoleCtrlDelegate consoleCtrlHandler = new ConsoleCtrlDelegate(ConsoleCtrlCheck);

        // Set the console control handler
        PInvoke.SetConsoleCtrlHandler(consoleCtrlHandler, true);

        // Keep the application running to test the handler
        Console.WriteLine("Press any key to exit...");
        Console.ReadKey();
    }

    // Callback method
    private static bool ConsoleCtrlCheck(uint ctrlType)
    {
        switch (ctrlType)
        {
            case PInvoke.CTRL_C_EVENT: // Handle CTRL+C
            case PInvoke.CTRL_BREAK_EVENT: // Handle CTRL+BREAK
            case PInvoke.CTRL_CLOSE_EVENT: // Handle console window close
            case PInvoke.CTRL_LOGOFF_EVENT: // Handle user log off
            case PInvoke.CTRL_SHUTDOWN_EVENT: // Handle system shutdown
                Console.WriteLine("Console control event received: " + ctrlType);
                return true;
            default:
                return false;
        }
    }
}

Hi!
Here is a correct implementation of the handler delegate.

private static readonly Windows.Win32.System.Console.PHANDLER_ROUTINE _consoleCtrlHandler = new(ConsoleCtrlCheck);

static void Main(string[] args)
{
    PInvoke.SetConsoleCtrlHandler(_consoleCtrlHandler, true);
}

private static Windows.Win32.Foundation.BOOL ConsoleCtrlCheck(uint ctrlType)
{
    // TODO
    return true;
}
