A Tour of Various TPL Options
The Task Parallel Library (TPL) exposes various options that give you more control over how tasks get scheduled and executed:
- Choose whether to optimize for fairness or for overheads when scheduling tasks.
- Specially mark tasks known to be long-running to help the scheduler execute efficiently.
- Create a task as attached or detached to the parent task.
- Schedule continuations that run if a task threw an exception or got cancelled.
- Run tasks synchronously.
Joseph E. Hoag’s article A Tour of Various TPL Options explains these options in detail, accompanied by examples of correct and incorrect uses.
