Asynchronous programming is a norm than an exception these days where every machine and server are packed with CPU. It would be a shame not to use the parallel processing power of the machines.
The Task Asynchronous Programming (TAP) model makes asynchronous programming a piece of a cake. In this video, I am going to walk through some of the basic functionality implementations of asynchronous programming using async/await of task asynchronous programming model implementation.
I am going to use an example of a driver delivering goods to a distribution center. Where multiple tasks can potentially occur in parallel, whereas there would also be some dependency between the tasks. This creates a near-real-time scenario of asynchronous programming.
Features used in this video are as follows:
1. async/await
2. Task.Delay
3. Task.WaitAll
4. Task.WhenAll
5. Task.WaitAny

Very clear and concise explanation. I read a few articles about it and watched some other videos but my concept was still not clear. You explained this very well. Keep up your good work.

at 17:18 , how did the async Tasks start, as soon as we declared the async task, does it start ? like on line 18 and 19 ?? As per my understanding we need to start the task using Task.run(() => { } ) also in .net core web API we use Async and Await in all the Action methods, how does it give benefit there ?

@DotNetCoreCentral 2 года назад

if you go through the video the two methods ReportToBackOfficeAsync and VerifyAsync internally use Task.Delay to mimick a new task.

@eliassal1 3 года назад

At minute 8:56, When you start using var driverTask, var verifierTask...... we get a warning when buildin as follows: All projects are up-to-date for restore. \Async.Await.Demo\Program.cs(14,27): warning CS1998: This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread. [\Async.Await.Demo\Async.Await.Demo.csproj] Async.Await.Demo -> \Async.Await.Demo\bin\Debug et5.0\Async.Await.Demo.dll Does this mean it is not a good practice

@DotNetCoreCentral 3 года назад

@Salam Elias, I am doing a Task.WaitAll just in the line below, which is a better approach. And if you use Task.WaitAll, you should not get the warning to use await, as Task.WaitAll is the same as calling await on each of the tasks but in parallel.

@hasan_shans 3 года назад

When we use async/await, does it create a new thread?

@DotNetCoreCentral 3 года назад

@Hasan Shans, it will borrow a thread from the thread pool internally.

@hasan_shans 3 года назад

@@DotNetCoreCentral But is there a scenario when it doesn't use a thread at all? Because a lot of people recommend this article, where it states that async doesn't use a thread: Stephen Cleary - There is no thread

@DotNetCoreCentral 3 года назад

@@hasan_shans Based on my understanding and tests that I performed, if you await immediately after making an async call, there is no new thread, as I explained in this video itself when I showed the behavior. At that point there is no incentive to create a new thread, instead, it will continue on the main thread.
