WebFeb 12, 2024 · An await expression in an async method doesn't block the current thread while the awaited task is running. Instead, the expression signs up the rest of the method as a continuation and returns control to the caller of the async method. The async and await keywords don't cause additional threads to be created. WebJan 13, 2024 · In this article. The Task Parallel Library (TPL) is based on the concept of a task, which represents an asynchronous operation. In some ways, a task resembles a thread or ThreadPool work item but at a higher level of abstraction. The term task parallelism refers to one or more independent tasks running concurrently.
