我正在使用Microsoft Reactive ExtensionsTask.Parallel中的类（.NET 3.5 库，而不是 .NET 4 中的类，因为我的应用程序在 3.5 上运行）。在 .NET 上一切正常，但是当我在 Mono（Linux 上为 2.10.5）中运行它时，调用该方法时会引发异常：Parallel.For()

System.Threading.Tasks.TaskSchedulerException: TaskSchedulerException_ctor_DefaultMessage

我在网上找不到任何涵盖此异常的资源，所以我有点卡住了。有什么建议么？3.5 的任务并行库是否在 Mono 上运行？
