Async/Await an Introduction (Asynchronous programming in .NET 5.0)

[@SohailKhan1981]

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.

@Sohail Sarwar, thanks for watching!

[@laughingalien]

Excellent work, sir! A very well thought out example. Thank you for sharing your knowledge.

[@DotNetCoreCentral]

Thanks for watching!

[@avinandanpatra8867]

Excellent explanation, could you elaborate ConfigurureAwait methods and its use

[@DotNetCoreCentral]

@Avinandan Patra, thanks for watching! I will create a short video on some of these features.

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]

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

[@sharadabasa6114]

Such awesome video for all those who get confused with async and await .... Thankyou

[@DotNetCoreCentral]

Glad you liked it

[@Shaikhbarkat09]

Can we create verifery async method without Task return type?

[@DotNetCoreCentral]

I am not sure I understand the question

[@juliansegura5507]

This might be the best tutorial I have seen about async/await

[@DotNetCoreCentral]

@Julian Segura, thanks for watching!

[@Madhavabakkamuntala]

It is awesome explanation done I hope you will do more vidios on Task

[@microtech2448]

Can you please explain with help of diagrams how and when threads switch and how they flow?

[@eliassal1]

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]

@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.

[@eliassal1]

@@DotNetCoreCentral Ok got it, happy new year and hope you do more wonderful videos

[@DotNetCoreCentral]

@@eliassal1 thanks! and happy new year to you as well!

[@MTSightseeing]

Can u make a video on asp. Net core api in depth

[@abidshaik9614]

Good one. Do a async await video with Database operations.

[@MTSightseeing]

Also make a video on repository pattern in api and mvc

[@DotNetCoreCentral]

Sure

[@MTSightseeing]

@@DotNetCoreCentral upload as soon as possible

[@hasan_shans]

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

[@DotNetCoreCentral]

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

[@hasan_shans]

@@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]

@@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.

[@hasan_shans]

@@DotNetCoreCentral thank you!

[@DotNetCoreCentral]

@@hasan_shans you are welcome!

[@VerdonTrigance]

why this is in 'advance' playlist? this is a basic stuff

[@harishkommuri5350]

Thank you, it was Indeed clear explanation, it was value add to me.
