Task Factories

.NET Framework (current version)

A task factory is represented by the System.Threading.Tasks.TaskFactory class, which creates Task objects, or the System.Threading.Tasks.TaskFactory<TResult> class, which creates Task<TResult> objects. Both classes contain methods that you can use to:

The Task class has a static property that represents the default TaskFactory. Typically, TaskFactory methods are invoked by using the Factory property, as shown in the following example.

[Visual Basic]

Dim taskA as Task = Task.Factory.StartNew(Sub( ...))


Task taskA = Task.Factory.StartNew( () => ...);

In most scenarios, you do not have to derive a new class from TaskFactory. However, it is sometimes useful to configure a new TaskFactory and then use it to specify certain options or to associate tasks with a custom scheduler. The following example shows how to configure a new TaskFactory that creates tasks that all use the specified TaskScheduler and have the specified TaskCreationOptions options.

class Program
   static CancellationTokenSource cts = new CancellationTokenSource();

   static TaskFactory _factory = new TaskFactory(
      new MyScheduler());

   static void Main(string[] args)
      var t2 = _factory.StartNew(() => DoWork());

   static void DoWork() {/*...*/ }
