- Let's start to explore one of .NET's favorite features, LINQ (Language Integrated Query). LINQ easily enables developers to write query expressions with a declarative query syntax that allow them to perform filtering, ordering, grouping, and so much more with minimal code. Scott and Stephen are back to take you through the depths of this awesome .NET technology.

Wake up babe, dotnet dropped another deep dive with Stephen Toub (we want more)
Absolutely
And longer, these teases are way too short. 😢
I want to absorb all the knowledge they have
Yes!!!! More, please :)
Stephen Toub is a great presenter and extremely knowledgeable, what a combo!
This combination is the main reason his videos are extremely exciting.
YES YES ... also Scott is also the BEST host I've ever seen ... he has amazing empathy to sense what we the audiebnce thinking and he calls it out
I'm a simple person, if Stephen Toub is in the video I'll watch it
Hour, hour and a half attention span? I'm waiting for the 5 hour Director's Cut Extended Edition.
Please, more Stephen Toub -- the deeper the better. Reminds me of the good old days watching Channel 9 in the early 2000s. It (at least looked like) a few guys walking around Microsoft with a video camera asking crazy smart people to explain incredibly difficult problems. It is fun to see smart people thinking hard whether I care about the particular technology or not.
This video is BETTER than ANYTHING on Netflix :) and the Suprise ending was so cool too
Thank you guys . Please don't stop those series
I love these deep dives! Even though I'm already familiar with most of it, there's always a few hidden gems to learn. And I also just enjoy listening to Stephen Toub explain these things from the ground up.
I love the time limit they impose because with someone like ST, you know you're going to get right to the meat of the discussion without a lot of cruft. And revisiting something we use every day to explain it in low level detail really helps understand the WHY behind the implementation. GREAT stuff Scott/Stephen.
I would love to see a part 2 with all of the potential optimizations.
When you peek unther the covers to see how a library or .net itself implements things, it's really easy to get lost in the code, but a lot of the complexity comes from optimizations that have accumulated over time. It'd be great to be able to build a mental catalogue of "optimization patterns" so that we have an easier time reading code. I think this series will help immensely with this.
I believe just listening to Scotts and Stephens friendly banter makes me a better developer! 🙂
That's how you teach dotnet, I will await for stephentoub
Keep this series going! Hard to find content like this, especially with this level of presentation.
Cheer up guys who is looking this now rather being on Netflix. Thanks Scott. Stephan while reading your old blogs post for async and stuff wished to see you like this and it’s dream true.
Please bring more stuff. This gives a great motivation as well. Thanks again.
This series with Scott and Stephen is the best programming-related thing I've ever seen on TH-cam.
Thank you so much!
I am loving these deep dives and the energy and enthusiasm between the two is fantastic. Not to mention the little things you drop in between like sealed classes, statemachine, profiler, benchmark, interlocked vs threadid kept me engaged.
Keep throwing these videos, we are happy to catch.
Awaiting for the next one..
I really enjoy watching and learning from you guys. Pedagogical side of thing is just brilliant. It's so useful when Scott once in a while "takes the foot off the gas pedal" to explain "simple" things like underscore in an integer to separate thousands etc. It's so deep and explaining things from the first principles. Understand once and apply everywhere. It's like a breath of fresh air in an otherwise clean-code and clean-architecture flooded environment.
Thanks, Scott, for stressing the environmental impact. It is at least as important as saving money❤
Great stuff! This session will be relevant for many years to come. Next up...Spans?
I've been waiting for a series like this for a Int64 time! What an amazing presentation. Please keep it up!
Brilliant stuff. Enjoyed it thoroughly. The great thing about this type of content is that it’s making me think deeper about the code I write.
These vids with Stephen Toub just pure gold
More of this, please. Scott and Stephen are great at these. Enjoyable, deeply satisfying and these peeks into the layer below my daily dev life are super interesting and are certainly having a valuable impact on my work. Just great stuff!
This is fantastic series. I barely watch movie nor TH-cam video more than once except this series. Thank you Scott and Stephen🎉🎉
Thank for taking the time to share all your smarts with us!
No session with Stephen Toub is ever long enough. Thanks guys that was awesome.
Thank you! Stephen is great at explaining code and Scott ask questions that I am thinking!
Awesome. Cant wait for a extreme deep dive extended directors cut version :D
Could watch this content all day long
Thanks a lot for the time you guys are putting on this. This is great stuff!
Very very very good video. Haven't seen such clean deep dive since Stephen's STL C++ videoes.
Thank you for the amazing Deep Dive series. We want more please 😊
I love the deep dive videos with Stephen. Please do more!
This kinda feels like the TH-cam version of the infamous C# in Depth (by Jon Skeet). Not to the extend where it will replace it (even if you get all the chapters), but in the sense that you get the same deep understanding of how the language works on a lower level. I really love it and hope to see more videos of this type.
Gold channel with gold videos.
Stephen Toub legend, thanks for videos with him.
Holy crap just finding out about these deep dives, literally cannot wait to finish this and click on the async/await one sitting in the "up next" section of youtube lol
it's nice to see this, please continue the series
Looking forward for the next part. Reflection is a topic I think a deep dive is interesting.
Just fantastic. As always. Thanks guys!
I am not even .NET but a Java developer. Still this video was a motivation booster for me and I can't wait to see the next one with the specific Array optimized version. Thank you!
Thank you! That is great video. Can't wait for more 🙂
Amazing video thank you Scott and Stephen !
A very useful series, thanks
Great video thank you very much. Bring some more goodies, please 🙂 but just remember about proper font size (thank you Scott 🙂 ). Maybe go even deeper with optimization, profiling, micro details. The check with current thread was really neat, I wonder what else Stephen keeps in his sleeves 🙂
Great series, looking forward to the next one.
The reason why the exception is thrown during the MoveNext call is the cursor, which keeps track of the items, is positioned right before the first item on the Enumerable. Similarly, the LINQ query is executed when it's used and not where it's defined.
I love these deep dives. Thanks guys.
This series is great!! Thank you!
Great show! Keep them coming.
Great is little word for what you both are doing, words can not describe it, please keep going.
thanks very much for sharing, love it, we want more please
I love it that there are still people who are actual Computer Science nerds out there. At the end of the day, a lot of syntactic sugar boils down to `1: doSomething(); 2: if not done, GoTo 1;`
1: Home
2: Sweet
3: GOTO 1
While this is very cool it's also worth remembering that LINQ to Objects (in-memory implementations like this) are just the tip of the iceberg. Expression trees and IQueryable is what sets LINQ and C# apart from similar in-memory techniques in JavaScript, Swift etc. They don't have a way to get the syntax tree and to allow the query to be translated to a completely different remote language like SQL.
awesome presentation! very interesting and very well presented! Thank you!
Would anyone else pay good money to see Stephen Toub do a dometrain-style course on performance profiling and optimization? Starting with how he thinks about performance optimization, talking about techniques and tools and then running through a robust example using everything he covered to optimize some piece of code... would be super cool if he did it for some open source project as a microsoft-sponsored demo using VS or any other stuff MS wants to showcase. Maybe a piece of OS code that MS uses internally but could never justify spending Stephens time on ;-)
We need more Stephens. Would be good for the next generation of programmers to have a solid-starting point for this kind of work.
Oh no, another video with Stephen Toub!!!
Keep these deep dives coming!
Thank you both, this was great, as usual… 👏🏼
This series is amazing!
A deep dive on DLR would be awesome. There is a lot of FUD about "dynamic" that proliferates.
this was just what i need it, thank you
Don't Stop these coming!
Keep 'em comin' :-) Parallelism, threading, optimisation, how to take advantage of all the language features next?
One of my favorite series!
I hope it’s a series
Thank you that was a great tutorial and very very insightful deep dive. Here we see linq is iterators all the way dow ;)
Also thank you Scott for constantly telling Stephen to stop zooming out. Its very hard for us trying to follow the super fast drain dump going on and suddenly the code becomes completely unreadable due to Stephen zooming out all the time.
I actually found that to be a little distracting
I love this series.
I would absolutely love more Stephen Toub videos! Please get him a decent microphone though, I find the difference in audio quality between Scott and Stephen is distracting
That was quite something! Thanks.
It's nice to get some dotnet content for experienced devs.
Love these deep dives...
That was great, thanks!
This is great! Thanks guys!
Hyped for part 2.
The original video got removed while I was watching it. My heart dropped a beat when the connection error popped up 😵
Surely Reset() is a member on IEnumerator because IEnumerator is C#'s version of the well documented (GoF) Iterator pattern, which is described as MoveNext(), GetCurrent(), and Reset()
If Stephen wasn't doing so much good work on everything he touches, I would say please make more videos! But I can't help worrying that every minute he spends explaining something to me, he's not making the language/framework more awesome. We need to clone this mans brain!
Very interesting, thanks!
Excellent talk!
Wow, this should be amazing
This was super interesting!
Wow, I am hooked 🤯👍
Great video.
I'd love to hear from more people from the fsharp side of life!! Get Chet Husk, Jimmy Byrd, Vlad Zarytovskii, Don Syme, the whole gang.
Awesome stuff!
love this vedio, youtube should pin it in the top of other videos!
yay it is back
Fantastic!!!!
this is dope.
Great. More More.
This is great
That was great
First I watched async/await video and thought that is too much for me. Now I'm watching this and find out even LINQ is too much for me :')
@14:17 What is the shortcut Stephen uses to go from the auto-suggested "Select" to "select"?
Most classes should be sealed! ;-)
I'm pretty sure the saying is:
The 2 hardest things in computer science are: Naming things, cache invalidation, and off-by-1 errors
Good stuff
didn't know you could goto a case branch to fall through!
the bell is smashed
This is amazing! But.. Toub uses VS in white mode? :O
Is the analyzer that makes classes sealed publicly available?
Probably an editorconfig setting
I came here to ask the same question. It would be useful!
I'd like to enter a hackathon... with Stephen Toub and David Fowler on my team.
