Async and await in C# example 

You taught me so many stuff that made me survive and stay safe at work, I really appreciate your effort, we need more great people like you.

In 11 minutes, you've wasted zero time on nonsense... All intuitive and thorough without the bloat. Thanks! I never find myself saying "hurry up!" during your videos.

I am from Russia and I do not speak very well English, but I understand all that you say, thank you

I am from Bangladesh. I'm Pias. This is my first comment on your video. Actually i have a question to you. Before asking I want to say you something from my heart. You are that person who is created by God's own hand. You can't imagine how great you are and how your every free video help a person to get a clear concept about their topic. Without your video it was impossible for me to learn SQL and C#. Thank you so much....God will be with you for forever. He will give you a large gift that you can't imagine. You are really a great one in this whole world. You are the real hero. You are such a teacher that i never ever seen in my whole life. Through your video i will also learn the rest of language that you teach. I will always remember you and your help. I have a great wish to see you in any way. If you don't mind could you give me your picture. it's my dream to see you. (Now question: I can't find a video on garbage collector in c# Could you help me please if there is a existence one..)

Thank you so much, I had an issue with my application in processing FTP, using async and await, and it died on me. You revived it. Thank you!

Mr.Venkat, you are the best instructor on the net and RU-vid, you have a special way of making easy simple, God Bless for all the help I got from your tutorials.

Hello venkat , this is a really awesome explanation of the async construct . I have a question :) I was wondering why the text Processing please wait doesn't get displayed , the instruction displaying it get's executed before the long-running task is reached . Any explanation would be appreciated .

In the beginning of the video, we see 3 steps in the button-click handler method. 1.setting the Processing file message to label 2. Calls countCharacters method 3. Setting the count to label When this message was running synchronously initially, it should display 1 because 2 is where it's taking time. Why doesn't step1 get printed ?

This tutorial was much easier to understand than most of the others I was seeing. Thank you!

I've not seen one of your videos for a while; and so forgot how good you are at knowledge transfer. I've tried teaching, it isn't easy, please keep it up because you're doing a great job.

I learn much easier visually. Thanks a bunch, been awhile since I've programmed in C#. I had used multithreading in the past, but it has been 8 or so years. This gave me a quick way of using newer and easier techniques to accomplish what I was looking for.

I am an Environmental Engineer with no prior experience in coding I learned from videos like these on the internet now I am an experienced Software engineer, Thanks for the content like these, Thanks for your work.

immediately subscribed, i am a noob fresh graduate in IT, and i have forgotten most programming concept, so i have a hard time to understand any guide or explanation on this async/await usage, but this video is so simple and clear to understand, thank you for making these videos, all of your videos explains clearly and simple

You're a great teacher Venkat, am confident writing c# now, i am one video away to completing the series :)

thank you so much mr venkat , you taught me the whole course , i will not forget u for the rest of my life, what a teacher, huge respect.

Dear venkat you are genius, master of Microsoft technology thank you very much.... I am software developer because of you....

Ten minutes are enough when you have a given to teach. Awesome explanation! Thanks a lot.

You have explained the async await part, but what about the Task part. What exactly is happening and why is task of type Task ? Thanks

Thank You so much for the explanation sir! If any of You guys are getting an error similar to "Task does not contain a definition for 'GetAwaiter' ", take a look at the .Net Target version of your project! It'll only work for 4.5 or newer.

Best video series ever, thank you so much I learned a lot from you.

Venkat, I have seen many many experienced developers making confusion between async/await, parralel task and multi threading. Can you distinguish between them and create a video.

By far the best training in c# on the net. Simple and concise.

I am putting my head on this for a while to comprehend this topic. But You nailed it, which you do every time. You are real boon for all .NET developers as me.

I am totally pumped that the C# tutorial saga continues!!!!

You are the father of teachers.

You are the best in the teaching world Venkat.

Wow, you actually talked about the reference when you started using a new namespace. Thumbs up for that.

Really Awesome . Your videos are really amazing easy to learn. Please add some videos from Design Patterns .

Thank you so much, You are a great person , You taught me so many stuff that made me survive and stay safe at work, I really appreciate your effort, we need more great people like you. Thank you again, one more knowledge is added

Thank you for sharing your knowledge, I hope you are attempting to prepare something about ASP NET 5, it would be wonderful

This kind explanation makes everyone a masters in async and await concepts. Thanks so much Sir

Thank you! You just saved me a ton of head ache! Thank you so much!. 8)

I have been watching you videos since I was in school, I really learned a lot from you sir. Thank you

Thanks a ton for this video. Very concise and clear tutorial for beginners

Your videos are very useful. Videos you make are simple, precise and informative. Please keep posting such videos.

I think you are the best teacher on the net, and wish if you could start " XAMARIN " Course.

Venkat Sir you have made our learning easier.Thank you so much for the videos.

Better than studying hours for hours in books and internet articles. Right on!

Video from 10:31 going on, I feel the freezing / non reactive problem was completely solved! Thank you very much. 😃

Wow I went from his 6th video to this and the audio quality has improved tremendously!! Great vids btw!!

Thanks Venkat, detailed and straightforward.

this is by far the best explanation I found for async and await. thank you

Excellent tutorial. I watched another one of your videos a while back. It was about 'IEnumerate' and it was a great tutorial as well. You're a good teacher.

అద్భుతమైన వివరన. ధన్యవాదాలు అన్న.

you are great venkar, your videos are very useful for every phase of development, as you can see there are lots of requirements of design patterns please explain it

The best teacher in the world

I am thankful to you for uploading your dot net videos , it is very useful to my prof career. thanks

Thanks Venkat,,one question, can we add more methods to the same task as in multicast-Delegates ?

wow very nice explanation

Great explanation with example within 11 mins.. Thank you Venkat.

Venkat, your videos are great. I love your teaching style.

what a great tutorial which teaches async and await in 12 minutes. thank you

Awesome Video and as always ... par excellence ! I had a doubt though ! In the first case (without the use of async and await) , why isn't the label displaying "Processing file... Please wait" ? It is before the CountCharacters() right ?

Very simple and efficient examples and explanations. Keep up the excellent work !

No Words can explain how did you do it so good in so good example, well done sir

Good way to explain ! Looked his web site videos and tutorials are in descent price ! Definitely worth the price .

I still remember back then in Framework 2.0 when Async/Await weren't even keywords in C#, You had to explicitly create delegates, callbacks etc in some verbose IAsyncResult, BeginInvoke() and EndInvoke() patterns and provide means to return to the main thread, so messy the code has become back then. Now async/await are doing great job dealing with that mess!

Thank You So much Sir.Last Video I Requested this Concept Now this Concept Started once again thanks sir.Keep Continue ..................

very good explanation and example, learn a lot from your videos. awesome example to compare with the thread. 👍

Very clear. Very easy to understand. Such a great video!

Hey kudvenkat, loved your practical explanation. I have a doubt, what if CountCharacters() method had a parameter type? How will we give those parameters in Task?

finally, I understand them clearly! thank you

Best simple example i've found in all internet lol

Thanks Venkat for all your videos.. I got a job after watching your videos :)

Very, very helpful. You can really teach and explain very well!

Nice and simple, straight to the point thank you

Why it didn't display "Processing File. Please Wait..." for the first time. It should display the "processing file" message and then the time consuming task and then the result?

Great video Sir!! It's simple and comprehensive and the explanation is too good.

Your tutorial still awesome even today

Greatly explained, thanks!

i love the way u teach.......... great work...!!

This channel is worth it, I'm gonna subscribe!

Very helpful and easy to understand..

Thanks Venkat AGAIN (first you taught me T-SQL) for your way of teaching =)

How to Pass Parameter in function like as Task task = new Task(MyCalculation("MyPara1", "MyPara2")); task.Start(); but its not working...

Venkat's teaching is the same as Kholi hitting a six even in difficult situations

Hi venkat, can you please help me understand how to update the progressbar while reading large XML files. Also the application should be able to resize or move around like you shown in this video. Thanks

Thank you so much, I have a method with parameters and its throwing a Cross thread exception while using Async and await Action. when I pass the parameters in Action Tasks, it throwing another exception " can not convert from void to System.Action" Please advise

So clear explanation, thank you so much

Amazing Tutorial! This is what I'm looking for.

Your videos are always great..your crystal clear explanation creates interest in all concepts you explain..Keep up the great work!!! It would be great if you upload a video series of c# Design pattern..Thank you!

Great video man! Life saver!!! 💯

all your videos are helped me a lot

This have been really helpful...Thanks a lot ❤

thanks the example works perfectly fine ! great video

Looking forward for the next video!

Really cool, thank you so much for sharing !

You are extremely awesome. However, found your pace of speaking is little high.

question, if await finished, the task will stop automatically? and if i have 4 method with different load txt . should i create 4 task start?

Hi Venkat, hope you are doing great. Could you please help me on how to process thousands of records in c#. Each record call a service to get some other details based on record id. Currently I am using paralell.foreach and it process 10000 record in an hour. Please suggest me how can I improve performance by 50%.

Great material, Venkat, thanks a lot!!

Great tutorial!

Perfect explanation👍👍

Does the task.start() executes on a separate thread? Then the next line i.e lblCount.text is executed by which thread? The main thread? Need some clarification, please.

Dear Mr. Venkat, can you please make some tutorials on design patterns!

best explanantion of Async

this guy is genius, Bro if you have full paid tutorials in udemy for building real projects let me know please

Great Example - Simple and short

Beautifully explained

i am getting an error, An asynchronous operation cannot be started at this time. Asynchronous operations may only be started within an asynchronous handler or module. Any thoughts? thanks
