The Task Parallel Library is part of the .NET Framework since .NET 4. It is a set of APIs that simplifies the process of adding parallelism and concurrency to applications.
The Task Parallel Library (TPL) is a set of public types and APIs in the System.Threading and and the System.Threading.Tasks namespaces in the .NET Framework 4 and up. The purpose of the TPL is to make developers more productive by simplifying the process of adding parallelism and concurrency to applications. The TPL scales the degree of concurrency dynamically to most efficiently use all the processors that are available. In addition, the TPL handles the partitioning of the work, the scheduling of threads on the ThreadPool, cancellation support, state management, and other low-level details.
What would be the best way to convert/wrap a "classic" asynchronous method that uses a callback to something that returns a (awaitable) Task?
For example, given the following method:
public void GetStringFromUrl(string url, Action…
So I was told recently that how I was using my .ContinueWith for Tasks was not the proper way to use them. I have yet to find evidence of this on the internet so I will ask you guys and see what the answer is. Here is an example of how I use…
I have three methods that I call to do some number crunching that are as follows
results.LeftFront.CalcAi();
results.RightFront.CalcAi();
results.RearSuspension.CalcAi(geom, vehDef.Geometry.LTa.TaStiffness,…
I have some library (socket networking) code that provides a Task-based API for pending responses to requests, based on TaskCompletionSource. However, there's an annoyance in the TPL in that it seems to be impossible to prevent synchronous…
What is difference between the below
ThreadPool.QueueUserWorkItem
vs
Task.Factory.StartNew
If the above code is called 500 times for some long running task, does it mean all the thread pool threads will be taken up?
Or will TPL (2nd option) be…
Does the task parallel library have anything that would be considered a replacement or improvement over the BackgroundWorker class?
I have a WinForms application with a wizard-style UI, and it does some long-running tasks. I want to be able to have…
Using Thread is pretty straightforward
Thread thread = new Thread(MethodWhichRequiresSTA);
thread.SetApartmentState(ApartmentState.STA);
How to accomplish the same using Tasks in a WPF application? Here is some code:

In one of my projects that's kinda an aggregator, I parse feeds, podcasts and so from the web.
If I use sequential approach, given that a large number of resources, it takes quite a time to process all of them (because of network issues and similar…
I've wondered this for quite a while, but never really found the answer.
I understand that it's a hint for the task scheduler where the task will run on, and that the task scheduler can (or nowadays will?) decide to instantiate a non-thread-pool…
I have the following code:
public static async Task Start(IProgress progress)
{
const int total = 10;
for (var i = 0; i <= total; i++)
{
await Task.Run(() =>…
In terms of performance, will these 2 methods run GetAllWidgets() and GetAllFoos() in parallel?
Is there any reason to use one over the other? There seems to be a lot happening behind the scenes with the compiler so I don't find it…
I am starting a new task from a function but I would not want it to run on the same thread. I don't care which thread it runs on as long as it is a different one (so the information given in this question does not help).
Am I guaranteed that the…
I have the following test code:
void Button_Click(object sender, RoutedEventArgs e)
{
var source = new CancellationTokenSource();
var tsk1 = new Task(() => Thread1(source.Token), source.Token);
var tsk2 = new Task(() =>…
I got this program that gives me syntax error "System.Threading.Tasks.task does not contain a definition for Run."
I am using VB 2010 .NET 4.0
Any ideas? any replacements for Run in .net 4.0?
using System;
using System.Collections.Generic;

Trying to understanding the difference between the TPL & async/await when it comes to thread creation.
I believe the TPL (TaskFactory.StartNew) works similar to ThreadPool.QueueUserWorkItem in that it queues up work on a thread in the thread…
