Nov 27, · Task Parallel Library (TPL), basically provides a higher level of abstraction. Fundamentally, it boils down to a “task” which is equivalent to a thread except that it is more lightweight and comes without the overhead of creating an OS thread. In other words, a task is an easier way to execute something asynchronously and in parallel compare to a thread.

Jul 16, · Multi-threading is a concept to run multiple operations concurrently in your process to achieve maximum possible utilization of the CPU power. A thread defines an execution path. When the process starts, it starts a thread which is called Main Thread. If your program has many complicated paths which do heavy lifting and execute lots of time

Remarks. This method can be used to execute a set of operations, potentially in parallel. The cancellation token passed in with the ParallelOptions structure enables the caller to cancel the entire operation. For more information, see Cancellation in Managed Threads.. No guarantees are made about the order in which the operations execute or whether they execute in parallel.

Dec 20, · Essentially you're mixing two incompatible async paradigms; i.e. Parallel.ForEach () and async-await. For what you want, do one or the other. E.g. you can just use Parallel.For [Each] () and drop the async-await altogether. Parallel.For [Each] () will only return when all the parallel tasks are complete, and you can then move onto the other tasks.

Task.Run will always make a single task per item (since you're doing this), but the Parallel class batches work so you create fewer tasks than total work items. This can provide significantly better overall performance, especially if the loop body has a small amount of work per item. If this is the case, you can combine both options by writing:
