These talks from Stephen are truly the best dotnet content available. Stephen has the knowledge and goes next level in explaining it extremely clear but simple and is just a joy to listen to.
This series is awesome, please keep it going for a long time. Stephen's knowledge is incredible and his enthusiasm is infectious. The dynamic between Scott and Stephen make this series unmissable.
I can't get enough of this content :) Who would have thought that an hour long video on spans is literally the most exciting thing on my feed this week!
Memory is on the heap, Span is stack only. You can use Memory just like any other non-ref type, but Span can be used only within the function. Also, Memory can be used in async await, while the other cannot (because of stack only constraint). Memory behaves like Span, but it is much closer to ArraySegment without being array only type. I don't think I have used this type anywhere, but I have seen it being used around the Stream class.
I hate that .NET Pipelines are all about numbers. What I would like to see, is pipeline of T, so I can have abstraction for any pipeline I want to build
That floppy drive jumper comparison got me. The assembly I could follow, ain't never heard of a jumper before. Today I learned a couple things! Great content!
Jumpers were a little switch on 3'1/2 floppy discs that revealed or hid a hole: very modern tech compared to the little adhesive tape you had to stick on 5'1/4 discs to achieve the same (that is write-protect your disc)
Excellent video, please keep Mr. Toub on a few more episodes. As of topics to cover if possible please make video on how to interop or preferably make binding of C libraries on .NET.
This is freaking awesome!!! Right from the source, you should build a comprehensive "deep C# course" with all of this, for people that would like to purse perf related topics. Right now, I don't think there's a place where you can do that. It's basically spread around books, courses, blogs, etc etc. Really nice this one.
I'm interested in the meaning behind that last constructor check. Also, what are the tradeoffs from the alternative implementations you mentioned? Would love to know more about Memory as well. I don't yet have proper intuition of how to use it.
Great series, loving it. Some of the topics I would love to see covered next: - how equality works (intermediate) - how the allocator and and the GC work (expert) - how exceptions work (expert) - how analyzers work - how generators work - how JIT works
Dotnet has many layers of abstractions in a good way. They are like magic. Watching this series is like those videos in which a magician explains how they are doing their tricks under the hood. I love it.
Awesome series! Please do a video on the async runtime of c# next about how the default task scheduler works, especially interested in knowing how tasks get scheduled and as developers using the async runtime how do we avoid common pitfalls of inefficient patterns
Best Content On youtube today. I love the relaxed page and the high intensity content. It's almost an anti pattern of all the click-bate, gapless, b-roll crap on youtube today. If stephen does a workshop of stuff like this in NDC London next year, I'll drop $2000 to attend like when Dave and Damiean did the early workshops on .net core in circa 2017.
I haven't seen Bart De Smet in years. Is he available to talk about IObservable? Why has there been less emphasis on it in recent times? Also IQbservable..
At 38:48 Toub is talking about how if you have a readonly span it will put it in the data block of the binary. Do things like ImmutableArray get the same benefit or is the JIT compiler extra aware of ReadOnlySpan to do that optimization?
My biggest question was how, using span, was the compiler able to keep such a tight loop when enumerating? Also could have mentioned that span does not allocate any memory or copy stuff around! This was a good one Scott/stephen! Thankyou
It does allocate memory for the Span (two fields), but it does on the stack, not on the heap. Also, since it only stores an address of memory and an int, no copy of data is needed. The tight loop is achieved because T reference is basically a pointer so for enumerating the only thing it has to do is add "one" to the pointer times length, exactly the same as an array.
Very nice explanation thanks a lot. I would like to see something related to streams and how they work I was always curious about that. If possible, of course. Thanks again .
Big thanks for the Deep .NET series, these are sooo great 🚀 One question regarding Span: Are there as many improvements in the compiler for netfx as in .NET too? Is it worth to update APIs in legacy code with the System.Memory NuGet package?
the people in chat being negative about copilot are gonna get behind if they don’t use the very powerful tools at our disposal. you really don’t want to be behind in a world with generative AI.
"readonly ref struct" appears in C# 8, while Span appreared earlier in .net core 2, and than Span was just a struct. Would be interesting to see how it evolve.
Tell us in the comment what you like and what you don't like. There are five videos now and I am still figuring out what are don't like. is there anything in these videos that we don't like, I don't think so.
How does someone even become as great as Stephen Toub, man the guy knows his stuff.
You do it as your fulltime job for multiple decades, haha.
Pray enough to the coding gods...j/k 😄
Man, these guys are killing it with the series -- great topics.

TimeSpan well spent! Thank you :)
Like video at 0 seconds just because of @Stephen Toub
Not you alone. I did exact same thing, because it's the wizards show!
Like this comment at 1 second because I had to stop to like the video first because of Stephen Toub
We need more Stephen Toub's
I can't get enough of this content :) Who would have thought that an hour long video on spans is literally the most exciting thing on my feed this week!
This series of videos featuring Stephen Toub is truly remarkable and incredibly interesting. Thank you!
It's crazy how simple Span is on the inside considering the impact it's had on .NET in recent years.
This is amazing!
Now I need a video on Multithreading and Parallel Processing from Scott and Stephen!
Dataflow...
Learning from Stephen Toub is such a pleasure, man is a .NET master!
How does Span relate to Memory? I'd love to see a follow up to this that gets into that detail.
Memory is on the heap, Span is stack only. You can use Memory just like any other non-ref type, but Span can be used only within the function. Also, Memory can be used in async await, while the other cannot (because of stack only constraint). Memory behaves like Span, but it is much closer to ArraySegment without being array only type. I don't think I have used this type anywhere, but I have seen it being used around the Stream class.
Love this series. keep it up
Every video with Stephen in it is a treasure
"Have you got anything without Span?"
"Well, there's Span Span List and Span, that's not got much Span in it."
Lobster Thermidor aux crevettes with a Mornay sauce, garnished with truffle pâté, brandy, and a fried egg on top, and Span.
Fantastic content guys!! Can’t wait for the next one. A deep dive into the GC would be cool
WOW!!! Love these series, please don't stop!
Awesome content. Please make a video on System.IO.Pipelines
I hate that .NET Pipelines are all about numbers. What I would like to see, is pipeline of T, so I can have abstraction for any pipeline I want to build
These guys taught us so many things in that small "Span" of time ! Thanks a lot 🙏 Stephen's knowledge is so valuable !
Please don't stop making these!
Great duo - love it that Scott wants it zoomed in :)
Scott and Stephen are doing a great job, all the best.

Scott and Stephen: Outstanding series!
Where we can learn this kind of stuff is actually very amazing.
Excellent video, please keep Mr. Toub on a few more episodes. As of topics to cover if possible please make video on how to interop or preferably make binding of C libraries on .NET.
Although I don't understand some things, I still feel excited. Please continue to keep up

Really nice this one.
I wanna watch Stephen build a complex project from start to finish. I would love to see how he works.
I saw Stephen Toub, I clicked.... freaking awesome presentation learned a lot from this.
I'm interested in the meaning behind that last constructor check. Also, what are the tradeoffs from the alternative implementations you mentioned?

Incredible as always
Excellent content. Also: these light mode users bring balance to the force
Keep posting Stephan! We need more content like this, Thank You
Dotnet has many layers of abstractions in a good way. They are like magic. Watching this series is like those videos in which a magician explains how they are doing their tricks under the hood. I love it.
Oh no, it happened again!
The video is over and I've already seen all parts of the series😢😂
Thank you so much! Love every second of it...
Scott and Stephen are a great combo. Looking forward to future presentations.
Awesome series! Please do a video on the async runtime of c# next about how the default task scheduler works, especially interested in knowing how tasks get scheduled and as developers using the async runtime how do we avoid common pitfalls of inefficient patterns
This was a great video. All I need now is another deep dive video into Memory to complete my understanding of it. Thanks again for such a great video.

I need to watch more of these videoes. It's just pure gold!
one of the best demo/tutorials I have ever seen about Span.
Keep this series going!
Man, you guys nailed it as usual, absolutely love these videos. GC next? 🙂
I haven't seen Bart De Smet in years. Is he available to talk about IObservable? Why has there been less emphasis on it in recent times? Also IQbservable..
I didn't plan on watching this til the end... very interesting and very well presented.
Like in the good old days of Channel 9 👍
Stephen Toub is my spirit animal. So smart!
That was wild, I definitely want to see a part 2. Would also be cool to go through stuff like MemoryMarshall and its methods
Good stuff! Loved it. Thank you dotnet team.
it was from a month and didn't see it till today!!! i hope next one would be Memory and Pipes and Channels
Looking forward to deep dives into memory of T, sequence of T, pipes and buffers.
its the only video I need to watch to learn what is Span in .net
Keep doing these with Stephen; would like to see more roll-your-own content, like the Async/Task video.
At 38:48 Toub is talking about how if you have a readonly span it will put it in the data block of the binary. Do things like ImmutableArray get the same benefit or is the JIT compiler extra aware of ReadOnlySpan to do that optimization?
You guys are awesome combo, thanks for the videos! :)
28:30 unsafe ist really a great keyword because it truly scares developers off ;)
The series is really great! Thanks for sharing! ME me I'd personally love to see how what lies under the hood of reflection.
Just Brilliant! Keep making more of these.. Thanks.
The worst thing about this show is its time constraint! Great content guys! Amazing :)
Pure Knowledge Sharing.. & No dumb podcast like others.. Truly Marvelous.
♥
StephenT and ScottH - nothing is better 🙂

I wish I could like this 💯 times
This is a treat
Very nice explanation thanks a lot. I would like to see something related to streams and how they work I was always curious about that. If possible, of course. Thanks again .
my new favorite tv show. Love it!
Async/Await

RegEx
Span
😀😀😀😀😀😀😀😀😀😀😀😀😀😀
Loving it.
Thank you very much. Great Content.
34:31 - Pause
39:00 - utf8 syntax from c# 11
I'm going to repeat myself, but thanks Scott and Stephen.
Another great session! Keep them coming 🎉
Show must go on
Big thanks for the Deep .NET series, these are sooo great 🚀
One question regarding Span: Are there as many improvements in the compiler for netfx as in .NET too? Is it worth to update APIs in legacy code with the System.Memory NuGet package?
I wonder what Scott is using a floppy for? :D Wonderful video, I hope we get more f this kind. Greetings from Norway :)
These kind of videos should be in 202 schools.
Best C# feature in 10-15 yrs.
Riffing off "Naming is hard":
Spam
Hmmm.
Thank you very much! Great content!
@37:11 - Stephen's fingers were off-by-one there.
Any interface for all collections (Array, List, etc) that can be converted to Span
the people in chat being negative about copilot are gonna get behind if they don’t use the very powerful tools at our disposal.
you really don’t want to be behind in a world with generative AI.
Any continuation of the series coming soon?
"readonly ref struct" appears in C# 8, while Span appreared earlier in .net core 2, and than Span was just a struct.
Would be interesting to see how it evolve.
I’m value added :))) thank you guys!
Thanks, very informative!
Amazing
Hello Scott/ Stephen
Please do videos about algorithms used in framework.
Please like comments who interested in this. They may do video.
well, this is awesome
When will we see next episode from Deep Dive series?
Can we have a video explaining ArrayPool and MemoryPool please?
knowledge SPANNING multiple videos.
Can you guys please deep dive the csc or the CLR?
Awesome ❤
Hi! Thanks for the video! Could you please record similar one about GC. Please 🥺
Tell us in the comment what you like and what you don't like.
There are five videos now and I am still figuring out what are don't like.
is there anything in these videos that we don't like, I don't think so.
I love this! Tanmirt!
rubbed my hands together and cackled when I saw this
At the beginning of the video, while using Rider and I'm like it's still hard to see the IL code in Visual Studio 😆😆
