Using System.Threading.Tasks.Parallel create new thread in the thread pool?

Question

Maybe I did not understand it right ... all the Parallel class issue :(

Parallel.Foreach does not create new threads, nor does it "mobilize all the threads". It uses a limited number of threads from the threadpool and submits tasks to them for parallel execution. In the current implementation the default is to use one thread per core.
