Dude this is the best video I have ever watched on this subject. You crushed this. No stumbling, no half-assing, no confusion. You were well prepared and taught everything perfectly. Just wanted to comment to let you know.
Best LINQ video in my opinion, and the only one you need to understand the topic, I just clicked on a whim, but I am glad that I did, thank you so much for making it.
Good vid. I have been doing c# among many languages for over 10 years now. Somethings if you never need it you just dont get to learning it yet from being busy so nice people make these vids.
Amazing video! So much effort; thank you. Once small point, I would cover the overload of Zip that takes a collection and a Func as an argument. That is probably one of the more powerful functions in Linq and strangely very few seem to know about it (it's up there with Aggregate)! One of my favorites is to check if a list is ordered (there are probably simpler ways but this is pretty show-offish) : var isOrdered = !list1.Zip(list1.Skip(1), (a,b) => a.Val
Thanks for the video, I have a question for Enumarable.Empty when you said the method is static, and every time we will get a reference to same collection. is it because *static* keyword ? Thank you again
I'm sure this has been asked many times but what do you use to draw the arrows and boxes on the screencast? Brilliant video btw - I was blinded by the pretty colours 🙂
Great work. Thank you very much to explain here in a concise manner. But there are a lot of courses like this on Pluralsight and Udemy. Anything new here? Do you have the plans to explore/explain Dynamic LINQ and using LINQ in async/await?
I've honestly never taken a LINQ course, so can't compare. Main difference is it's free 🙂 The video in 2 weeks is about PLINQ which from my experience most devs aren't familiar with
Hi Amichai, I want to learn C# and ASP to build web application. Which course do you recommend? Do you have of your own, I like the way you explain. From absolute beginner to Mastery as a beginner.
Hey, I don't have such a course yet. If you want to build a system following clean architecture then I'd definitely recommend taking my 2 clean architecture courses. But I wouldn't take them if you're still lacking knowledge in the basics of C#/ASP.NET
How can I know if a linq method is immediately executed or not - other than looking it up or memorizing it? I hovered my mouse over some linq methods and I didn't see anything that would indicate as such. Thanks.
Documentation mostly. You can use common sense for most methods (like count, contains must be immediately executed etc). Plus all methods prefixed with To (ToArray etc’) will be immediately executed as well
So is the only difference between ToLookup() and GroupBy() having an indexer? Also, given that there's a Zip() method, to effectively Unzip() a ValueTuple[] into a Tuple, is there an ootb LinQ approach, that does not involve multiple enumeration?
Typically, these long formats get boring and its easy to stop following. Not the case for this one! Great video, quite a few LINQ methods that you don't typically use. Side note - what do you use to draw on the screen? That is really useful?
Cheers 🥂

There's no reason why I should not like this video. Amazing effort, thank you Amichai 🙏
Liked and already subscribed. Am waiting for the PLINQ course! Never heard or used PLINQ but sounds useful. Thanks you!
Best LINQ video ever. I’ve been using LINQ for a long time and didn’t know half of these methods. 😃👍🏼
Phenomenal and comprehensive guide! Incredibly helpful! Thanks
This was the only video I needed to get comfortable with LINQ. Thank you.
I'm not a developer, but I do write code to test software, and I learnt some very nice things here. Great video!
This is amazing indeed!! I have subscribed immediately.
Great video to know about LINQ methods in C#. I was looking for such a video to understand LINQ much better and deeper.
Good vid. I have been doing c# among many languages for over 10 years now. Somethings if you never need it you just dont get to learning it yet from being busy so nice people make these vids.
Marvelous, love such style of video that introduces bcl
Awesome video! Well done, Amichai.

Can’t believe I didn’t know about this until now 🤯
Well explained.
thanks for covering all the LINQ methods 🙌🙌🙌🙌 . waiting for PLINQ
This is gold. Thank you for the video :)
This video was perfect, thank you!
Thanks, man... no bullshit... just an explanation...
Learned a bit about the lesser used LINQ extensions.
סרטון מצויין.תודה רבה.
Extraordinary !
Your explanations are really simple enough and easy to listen and follow. I also have a question, what is the on screen drawing tool you are using?
Presentify
Great work. 👏👍
Hi! Amichai! Which tool are you using for drawing boxes and arrows during the presentation? :)
Presentify 🙂
Great video! Thank you for your effort!
What software do you use for creating these boxes and arrows as you drag your mouse?
Presentify
Great work. Thanks a lot!
Consider making a tutorial about all types of lists :)
I should be filming "every single collection type" tomorrow 🤙
Thanks for the video, I have a question for Enumarable.Empty when you said the method is static, and every time we will get a reference to same collection. is it because *static* keyword ?
Thank you again
Yep
Your effort on this 🥰
which tool you are using and how to set this up?
What are you using to get realtime visualization of the collections?
Awesome content
@amantinband Where can we find the reactive readme that you have in your video ?
It's available for Patrons (link in description)
Great video
great video !!
one more thing, is there any way to share your README file on this video ? (look like the whole function list)
cool thx
תודה 😃😃
I'm sure this has been asked many times but what do you use to draw the arrows and boxes on the screencast?
Brilliant video btw - I was blinded by the pretty colours 🙂
Amichai. Please share your terminal set up. Especially the vim bindings in your terminal pls!
My setup is available here: github.com/amantinband/dotfiles
@@amantinband Awesome. Thanks for the prompt reply and I love your content btw! (bought your content on dometrain :) )
Off topic: How did you make ZoomIt draw rainbow-colored squares and arrows?
Great work. Thank you very much to explain here in a concise manner.
But there are a lot of courses like this on Pluralsight and Udemy. Anything new here?
Do you have the plans to explore/explain Dynamic LINQ and using LINQ in async/await?
I've honestly never taken a LINQ course, so can't compare. Main difference is it's free 🙂
The video in 2 weeks is about PLINQ which from my experience most devs aren't familiar with
Design patterns videos perhaps?

ASP is a framework built on top of the C# language last i checked
amazing
I think I broke my subscribe button this time.
Hi, thanks for creating video, i have watched the complete video, also can you please create video on all ef core methods.?
That’s a great idea. Added to my backlog
@@amantinband Great. Thanks a lot.

ToLookup is immediate execution and GroupBy is deferred execution
Aaaah okay there's the detail I overlooked. Thanks :)
Does that dump method work with more complex objects?
Yep. Any object
nice content
Awesome
Awesome! *****
Amazing video one of the best about LINQ Extension Method
but could you please share readme markdown file
thank you alot for your effort
I love LINQPad
goated!
Typically, these long formats get boring and its easy to stop following. Not the case for this one! Great video, quite a few LINQ methods that you don't typically use.
Side note - what do you use to draw on the screen? That is really useful?
Amazing to hear. I use presentify for drawing (it's MacOS only)
Great video, just an observation, at few important places you seem to be running too fast.
Holy fuck that thumbnail
Can't be all of them. U don't have mine.😂
You're going too fast...sorry!
That's what she said😭
@@stephen_2091 Is it really that offensive, to say that he's talking too fast? 🤔
Audio is terrible
damn, anyone else think so?
Nope, audio is pretty good
audio was fine for me
