TPL使​​用任务调度程序来协调任务。据正式文件，默认任务调度程序使用线程池，但是，如果 TaskCreationOptions.LongRunning 选项psented那么它会创建一个专用线程，该任务（A）。

TPL uses Task Schedulers to coordinate tasks. According to official document, default task scheduler uses Thread Pool, but if TaskCreationOptions.LongRunning option is presented then it will create a dedicated thread for that task (A).

问：截至目前MSDN文档为Visual Studio 2010还没有准备好和当前在线MSDN尚未敲定;没有任何人知道，如果（A）是真还是假？

Question: As of now MSDN documents for Visual Studio 2010 are not ready and current online MSDN is not finalized; does anyone knows if (A) is true or false?

推荐答案

是 LongRunning 强制创建池外一个新的线程。下面是最新的架构版本的一些伪拆解code：

Yes, LongRunning forces the creation of a new thread outside the pool. Here's some pseudo-disassembled code from the latest framework version:

...
if (task.Options HasFlag LongRunning) then
    create new Thread thread
    thread.Start(task)
...
