c# - TaskPoolScheduler 抛出 Win32Exception (0x80004005): 访问被拒绝 (XP, Rx2)

Question

我正在使用 Reactive Framework 2，但它突然从 XP 机器上的 TaskPoolScheduler 抛出 throws Win32Exception，但它看起来不可重现。堆栈跟踪非常有限，知道吗？

2013-07-02 15:19:38,209 [31] ERROR MyUnhandledExceptionHandler : AppDomainUnhandledException
System.ComponentModel.Win32Exception (0x80004005): Access is denied
  at System.Reactive.Concurrency.TaskPoolScheduler.<>c_DisplayClass2`1.<>cDisplayClass4.<Schedule>b_1()
  at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
  at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
  at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
  at System.Threading.ThreadHelper.ThreadStart()

它应该来自 Rx v1，因为调用堆栈是如此“空”：

// decompiled by ILSpy
public IDisposable Schedule<TState>(TState state, Func<IScheduler, TState, IDisposable> action)
{
    if (action == null)
    {
        throw new ArgumentNullException("action");
    }
    SerialDisposable d = new SerialDisposable();
    CancellationDisposable cancellationDisposable = new CancellationDisposable();
    d.Disposable = cancellationDisposable;
    this.taskFactory.StartNew(delegate
    {
        try
        {
            d.Disposable = action(this, state);
        }
        catch (Exception ex)
        {
            Exception ex2;
            Exception ex = ex2;
            Thread thread = new Thread(delegate
            {
                throw ex; // Here
            });
            thread.Start();
            thread.Join();
        }
    }, cancellationDisposable.Token);
    return d;
}

谢谢

我已经下载了 Rx 2.0.3，但我找不到System.Reactive.Concurrency.TaskPoolScheduler.<>c_DisplayClass2'1.<>cDisplayClass4.<Schedule>b_1(). TaskPoolScheduler 位于System.Reactive.PlatformServices.dll（在所有平台上），但它不包含此类子类/方法。

您使用哪个版本的 Rx？你试过最新的吗？
