Question: Consider alternative

[MHDante]

Hey, I was quite fond of finding this package, however, It seems a bit brittle to modify the IL directly. It falls strictly into the realm of "dark magic" 🧙

I've achieved similar success by calling the dispatch method myself:

using System;
using System.Reflection;
using System.Threading;
using UnityEngine;

public static class WebGlThreadPoolPumper
{
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.SubsystemRegistration)]
    public static void StartPumping()
    {
        if (Application.platform != RuntimePlatform.WebGLPlayer || Application.isEditor) return;

        var dispatchMethod = Type
            .GetType("System.Threading.ThreadPoolWorkQueue")?
            .GetMethod("Dispatch", BindingFlags.NonPublic | BindingFlags.Static)?
            .CreateDelegate(typeof(Func<bool>)) as Func<bool>;

        Pump(dispatchMethod);
    }

    public static void Pump(object dispatchMethod)
    {
        var method = (Func<bool>)dispatchMethod;
        var didFinishWork = method();
        SynchronizationContext.Current.Post(Pump, dispatchMethod);
    }
}

However, this may not be as robust as your solution. In particular, I'm not sure I understand why the timer callback is necessary. (is it for time-sensitive callbacks?)

Hi! in fact, it's a great option but my intention was to mimic mono-wasm ThreadPool behaviour. It included updated code for GetMinThreads, GetMaxThreads, SetMinThreads, SetMaxThreads and GetAvailableThreads. Also, my wanted to rewrite System.Threading.Timer but I have used your solution to run System.Threading.Timers in newer versions of Unity 😄

Also, I'm thinking about commenting all "dark magic" methods with the example code that they generate and how they do it.

This is off-topic, but @VolodymyrBS emitting raw IL to patch mscorlib is a feat of engineering you rarely ever see. You, sir, are an artist of the highest abilities. I'm a huge fan 🤯 .

My thoughts exactly. 😊 I really appreciate the effort!

any blog artic for us to learn this dark magic ，栓 q~

I could not get this implementation to work for me with 2023+
