Programmer will no longer have to manage the low level threads. A thread from the thread pool will execute the created task.

Following are the ways to create tasks :-

1. In the following code, we are creating and running the task in some other thread.

Task.Factory.StartNew(() =>
{
    Console.WriteLine("Some work done.");
});

2. In the following code, we are first creating the task and then starting it to run it on another thread.

var task = new Task(() => Console.WriteLine("Some work done."));
task.Start();

Lets’ jump into some details.

• StartNew method which we have used takes an Action delegate as an argument.

public Task StartNew(Action action)

It means either we can pass

1. A delegate as an argument

Action action = () => Console.WriteLine("Some work done.");
Task.Factory.StartNew(action);

2. Or a function which takes no argument and returns nothing.

Task.Factory.StartNew(() =>
{
    Console.WriteLine("Some work done.");
});

Overall, there are 2 ways to create the task and run it as explained in the first half of the articles.
