Tasks
Explore how to create and manage asynchronous operations using the Task Parallel Library in C#. Understand how tasks provide status tracking, return values, and allow waiting for completion, improving control over multithreading compared to traditional ThreadPool usage.
In the previous lesson, we used ThreadPool.QueueUserWorkItem to run code in the background. While efficient, it had a major limitation: we had no easy way to know when the background thread finished. This forced us to use Thread.Sleep to prevent the application from closing.
To solve this, .NET provides the Task Parallel Library (TPL). The TPL is based on the Task, which represents an asynchronous operation.
Think of a Task as an object representing an asynchronous operation running on the Thread Pool that provides:
Status tracking: Know if the work is running, completed, or failed.
Control: Wait for the work to finish. ...
