As someone who have learned async as "This is how you do async in the code. Don't ask why just do it" I never really understood why. I understood that the program could run asynchronous but never really grasped why or rather how it ran asynchronous. After the 25 minute mark I got the Ooooh now I get it. Thank you so much.

Before I watched this, based on everything else I had watched, I just though Async methods always had to be followed with Await keywords next to the sub tasks within the methods even though they were completely unrelated sub tasks.

Now over to your advanced async video!

I did that following the provided tutorial but that didn't help understand what is going on exactly. Plus it's always better to see it explained in a simple app like what you did. Thank you for this tutorial. For me 30 minutes is considered a short tutorial. 10-15 would be too short to understand and this was perfect and straight to the point. You explained everything in a couple of different ways and never strayed away from the topic at hand. It's rare to see such well structured tutorials. I will be back for more!

[@camrws]

what are the potential benefits of using the native async implementation of a method (download website in this case) instead of just wrapping the synchronous?

[@bennysaa]

Really good question.

[@IAmTimCorey]

There are a few. First, an async-native method can properly handle a cancellation token. That means you can cancel long-running tasks, stuck tasks, etc. You cannot do this with converted methods. Second, an async-native application knows how to interact with other resources while in another thread. Synchronous methods assume they are on the same thread as the UI so they may interact with the UI or other resources. That can cause threading issues.

Sir, you're the best. I've watched like 5-6 videos about that but couldn't understand when we have to use await when not etc. But all of them clear now. Thank you for teaching! ❤

[@sashithafonseka]

Hey Tim, Thanks for the insightful video. A question here, could you explain a bit more on why returning void in an async method (except in an event) is considered a bad practice?

[@IAmTimCorey]

Because the method cannot communicate a failure to you.

[@jonathanharmon3472]

To expand on what Tim said, if it's void, you don't have the Task object, which can contain any exceptions that might have occurred while awaiting the task.

[@sashithafonseka]

@@jonathanharmon3472 and @IAmTimCorey thank you for the clarification!

[@dand4485]

Great explanation, what i found interesting from what it appeared to me the order of the results came back in the same order for the Sync and Async. Just a bit strange but i really doubt you're doing anything weird, sure you'd agree order shouldn't be deterministic but just happened this way by random chance. But this was great explanation and above all don't want my comment to take away from how good the video is, just an observation, guess that's why i'm a tester at heart :)

[@dennisekkelenkamp2303]

Do you mean in the 'parallel' method? The tasks could have finished in any order. But the result array will contain the results in the same order as the Task[]. (So, tasks[0].Result will be in results[0], tasks[1].Result in results[1], etc) That's why the foreach loop will always enumerate them in the same order.

[@dand4485]

@@dennisekkelenkamp2303 Ah perfect, i see my mistake, thanks for your kind response, thiink i see my mistake. The list will contain the items in order as how you added them... (duh, shouldn't watch these at 1am when i'm not thinking straight...) Think my erroneous thinking is a hold over to the old ways of treaing i.e. a thread pool and worker threads, that's me, wanting to over complicate it :) And that might be true under the covers in the state machine which .Net/C# is providing but we only have the reference to the object in the list Task, an they will be in "insertion order". Thank for the clarification perfectly clear now :) Have a GREAT DAY!

[@IAmTimCorey]

Nice job both of you. I'm glad to see you both contributing positively to the community. Thanks for watching.

[@wildKawa]

Hmm... how would i go about adding a try/catch in the async function? Some of the listed websites sometimes send back an error - i added a try catch block to simply print "protocol error" in these cases, but in the async function that ends up crashing the program with "The calling thread cannot access this object because a different thread owns it." I assume that happens because my try/catch is in the WebsiteDataModel which isn't async itself? Cheers!

[@siggimund]

This is how I solved this: - Add property 'public string WebsiteStatus { get; set; } = "Ok";' to class 'WebsiteDataModel'. - When calling 'client.DownloadString/DownloadStringTaskAsync' 'catch' the 'WebException' and save 'webException.Status' (and maybe 'webException.Message') in 'output.WebsiteStatus' - Add 'data.WebsiteStatus' to the 'resultsWindow.Text' string in 'ReportWebsiteInfo()' to display it.

Great video, you explain things very well. I think, however, your parallel method isn't actually running parallel rather its running concurrently.

[@IAmTimCorey]

That is up to the system. It determines whether to run them concurrently or in parallel based upon how expensive it is to spin up a new thread vs how long it will take waiting on an existing resource.

[@chadiusmaximus9350]

@@IAmTimCorey ahh ok, I'm coming from Go where you have to write your code either concurrent or parallel. So you're saying the the .Net runtime handles that automatically? Rob Pike gives a really good talk on the subject.

[@raus_mit_Islam]

I still am confused: does the calling thread wait or continue while await is working?!

[@IAmTimCorey]

That particular method waits when you call "await" but it releases the thread back to the caller (usually the UI) to continue doing other work as long as that work doesn't depend on the results of the await.

[@raus_mit_Islam]

@@IAmTimCorey Q1: the released thread will join other yet not used threads, thus decreasing the risk that the appl runs out of threads? Or, will it immediately be assigned to specific work? Q2: given that the await’ed flow (fx of reading a file or performing a HTTP request) is without a thread, what ressource does it have? Reading from a file still needs processor power and RAM I suppose.

[@crabjuice47]

Very complicated. Thanks for making it, I appreciate that but if you are new to async this won't work as a tutorial. I think starting from a blank code will be better.

[@IAmTimCorey]

This basically was a "blank slate" project. The only things I did were to get a basic UI together so you didn't need to watch that and I created some basic code to call that was expensive. That "expensive" code can be anything you want and you don't even need to know what it does. The only way I could have done that with any less would be if I had built those two things on screen (but you would not have gotten anything else out of it since I explained both at the beginning), so it would have made the video longer but not added any real value to the topic.

THANK YOU Tim! This is such a clear explanation on Asynchronous. It blew me away! To think I've been programming most of my life linearly (except for a few multi-threading things I've done). I am a new fan of your series!

[@IAmTimCorey]

You are most welcome. Thanks for watching.

I think this is the best video you’ve made. They are all great, this one is next level good.

[@IAmTimCorey]

I appreciate the kind words.

I do .net software dev for a company, and I watch a lot of videos on topics. Lots of people have different ways to complete tasks. It explains every step. We use .net c# for mostly report generation that is customized to client needs, where SSRS isn’t a great option. I will for sure be using async/ await from now on!

[@david-xw4ug]

Can't believe I understood ever word in the video! Thank you for the excellent work!

[@IAmTimCorey]

You are welcome.

Thank you so much. The only tutorial that made me understand properly, and I really like that fact that you explain that this is demo and not for production.

[@IAmTimCorey]

I am glad it was helpful.

Thank you so much Tim. These really helped me understand async await better than the other youtube videos. It really helped me.

[@IAmTimCorey]

Awesome!

I'm having to "learn" a new project at work and a lot of it is new technology and a new style for me... I can tell that the developer that wrote it learned a lot of it from your videos. This helps a lot.

[@IAmTimCorey]

Great!

[@david3552]

You and your videos are fantastic. Learning async using the offical documentation felt kind of daunting and convoluted. You made it clear!

[@IAmTimCorey]

I appreciate the kind words.

Your making programming easy to learn, I've been programming c# for a year so not much knowledge. But the knowledge i do have is because of your explanations!! Awsome video. Thank you

[@IAmTimCorey]

Great to hear! Stick with it.

[@walius1988]

Because of your videos, I am getting better and better in C#. Thank you a lot!

[@IAmTimCorey]

You are welcome.

You are an amazing teacher. I do programming as a side hobby, and for years had avoided dealing with async methods because I couldn't understand them retorting to the old backgroundworker instead. I watched this video and understood what I needed to do and bam, first I changed my code to make it asynchronous, and then to make it work in parallel. I'm looking forward to watching the next video about the progress reports, hope I understand and implement that one as well.

[@IAmTimCorey]

I am glad it was so helpful.

It has literally just become a habit to like these videos before they even begin lol. Great work explaining this.

[@IAmTimCorey]

Thank you!
