❔ Checking if ISymbol was autogenerated

Hello, is there any way to check if ISymbol was autogenerated by c# compiler? In this case checking for specialname attribute should be ok. I want to filter out autogenerated symbols such as methods generated from autoproperties or enums' value__ field.

✅ ClientWebSocket concurrency question

Hello. Can ReceiveAsync and CloseAsync methods be used concurrently? And also the same for SendAsync and CloseAsync (this one sounds a bit funny but it's serious). The documentation doesn't say anything about concurrency for CloseAsync.

❔ ❔ ❔ SemaphoreSlim that can be entered without waiting

Hello, I am trying to find way to easily control how much threads can enter semaphore. I need something like SemaphoreSlim but that supports entering without waiting or Releasing with minus values. For example:

await semaphoreSlim.WaitAsync();
try
{
  if (something)
    semaphoreSlim.Release(10); // allows 10 more threads to enter
  else
    semaphoreSlim.Release(-10); // limits 10 threads from entering
}
finally
{
  semaphoreSlim.Release();
}

await semaphoreSlim.WaitAsync();
try
{
  if (something)
    semaphoreSlim.Release(10); // allows 10 more threads to enter
  else
    semaphoreSlim.Release(-10); // limits 10 threads from entering
}
finally
{
  semaphoreSlim.Release();
}

I there any built in object to do it? I really don't want to implement such thing myself.

Process.EnableRaisingEvents does not work on Windows

I have an app that have 20 workers that are other processes. On production, on ubuntu, when I close the main process with ^C, the workers die as they should, but on Windows, when I kill the process, the workers still exist and use 100% of my i9-12900k (lol), it's because the workers have endless loops and throw exceptions in them when there is no main process. When I close app console window, the main process and workers are not closed and when I kill the main process, I have 100% of cpu usage. Did I miss something? I use this method to create a worker:

        private Process CreateProcess()
        {
            var process = new Process()
            {
                StartInfo = new("ScriptingService", _arguments),
                EnableRaisingEvents = true,
            };
            process.Start();
            return process;
        }

        private Process CreateProcess()
        {
            var process = new Process()
            {
                StartInfo = new("ScriptingService", _arguments),
                EnableRaisingEvents = true,
            };
            process.Start();
            return process;
        }
