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).
Question: As of now MSDN documents for Visual Studio 2010 ar开发者_StackOverflowe not ready and current online MSDN is not finalized; does anyone knows if (A) is true or false?
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)
...
Edit: converted from ugly C# to pseudocode.
Presumably you can check this by using "Thread.IsThreadPoolThread":
