如何在没有STA警告的情况下在MSTest中使用WaitHandler.WaitAll？

Task[] tasks = new Task[2];
tasks[0] = Task.Run(() => DoSomething());
tasks[1] = Task.Run(() => DoSomethingElse());

Task.WaitAll(tasks);

public async Task MyTestMethod()
{
    Task task1 = Task.Run(() => DoSomething());
    Task task2 = Task.Run(() => DoSomethingElse());

    await Task.WhenAll(task1, task2);
}

[TestMethod]
[Apartment(ApartmentState.MTA)]
public void MyTestMethod()
{
    AutoResetEvent[] autoResetEvents = new AutoResetEvent[2];
    autoResetEvents[0] = new AutoResetEvent(false);
    autoResetEvents[1] = new AutoResetEvent(false);

    ThreadPool.QueueUserWorkItem((state) => { DoSomething(); autoResetEvents[0].Set(); });
    ThreadPool.QueueUserWorkItem((state) => { DoSomethingElse(); autoResetEvents[1].Set(); });

    WaitHandle.WaitAll(autoResetEvents);
}
