但是,AsyncLocal令人讨厌的行为是它“流动”到子线程.这与ThreadLocal不同.反正有没有阻止这个？

class Program
{
    private static readonly ThreadLocal<string> ThreadState = new ThreadLocal<string>();
    private static readonly AsyncLocal<string> AsyncState = new AsyncLocal<string>();

    static async Task MainAsync()
    {
        ThreadState.Value = "thread";
        AsyncState.Value = "async";

        await Task.Yield();

        WriteLine("After await: " + ThreadState.Value); 
        WriteLine("After await: " + AsyncState.Value); // <- I want this behavIoUr

        Task.Run(() => WriteLine("Inside child task: " + ThreadState.Value)).Wait(); // <- I want this behavIoUr
        Task.Run(() => WriteLine("Inside child task: " + AsyncState.Value)).Wait();
