Does the use of async/await create a new thread?

• No new thread creation by await:
  The await keyword itself does not create a new thread. The task that is awaited might be executed on another thread, but that's determined by the task itself, not by the await keyword. 

No, the await keyword in C# does not inherently create a new thread. Instead, async and await enable asynchronous operations that allow a method to yield control back to the caller while waiting for a task to complete, without blocking the current thread. The awaited task may or may not be executed on a separate thread, but await itself doesn't dictate that.
