Question

The Microsoft .NET Base Class Library provides several ways to create a thread and start it. Basically the invocation is very similar to every other one providing the same k

Answer 1

You should use ThreadPool.QueueUserWorkItem except in cases of:

• You require a foreground thread.

• You require a thread to have a particular priority.

• You have tasks that cause the thread to block for long periods of time. The thread pool has a maximum number of threads, so a large number of blocked thread pool threads might prevent tasks from starting.

• You need to place threads into a single-threaded apartment. All ThreadPool threads are in the multithreaded apartment.

• You need to have a stable identity associated with the thread, or to dedicate a thread to a task.
