We need more. Please a deep dive on Expression and Expression Trees !

[djchrisi]

This is really gold. I would appreciate a deep dive into reflection.

[weneedlittlepatience]

Could we get a Span<T> from scracth? 👀

[johndonaldmelville]

Loving the Hanselman + Toub collaboration. I agree this one was much more user focused than the others. I still love seeing under the covers of c#. I would recommend span and ref structs for a future episode.

Thank you Stephen Toub and Scott Hanselman for these videos.

Even with such a busy schedule you're teaching us.

[marklord]

Loving this series so far and very useful topics being covered.

[talkalderon]

Will really like to hear Deep Dive AsyncLocal<T>

Thanks again, Stephen and Scott, great as usual. 👍🏼
I'm very happy that you don't use a dark theme, and also that you use a big zoom factor. 👍🏼👍🏼
I can hardly wait for the next episode, thank you. 👏🏼

I didn't think a session about regex could become so interesting. I'm glad I clicked to start playing. Thanks for the series! It's been awesome!

[burndasbr]

Please do an episode where you implement a Source Generator.
They're so cool, but there isn't that much deep diving yet easy to understand content about it.

[aimafirm]

Thanks so much for this series! What a dream team here, plus most relevant topics.

What a brilliant concept to create a C# code file rather than using reflection.emit. By allowing the compiler to optimize code execution before it's statically integrated into the binary, as opposed to compiling it at runtime, efficiency is significantly enhanced. This capability is exclusive to constant regex strings, as they are transmitted as attributes.

This series should be C# 101 learning library. I hope we ll see more content like this. Thanks for your time Stephen and Scott you are rock.

[imranhussain]

Friend: Which Series are you watching these days?
Me: Deep Dot Net.

[LasseVagstherKarlsen]

I would be interested in a discussion around Span<T>, and why, as an example, it can't be stored on the heap. Not a 1 hour talk though, but perhaps as part of a bigger topic. Maybe a deep dive on the garbage collector would be an idea.

In any case, thank you both so much for this series of videos, keep churning them out as fast as you can, I've learned something new from all of them so far and to the level you guys are taking it, I'm sure I will learn something from every one you release, so keep'em coming.

[MatteoGariglio]

Very very valuable series of videos. Thanks for organizing it and share this content.

[adamliedloff]

Thank you Scott and Stephen. Simply the best series of code videos I’ve seen. Love the choice of topics. I use them all, but still had an underlying fear that I didn’t really understand them and wasn’t using them correctly. All now totally demystified and I’m going back through code to clean it up. Oh, that feeling of clean code with no niggling gremlins lurking.

Fun thing. I learned how to use Regex by reading the ME editor manual that came with MS C/C++ 5.1 (that was the late 80's). Roll on 40 years and in my last job I was considered a mage because I could do regex (our product exposed the Java RE engine for config settings).

The support team worshipped me 🙂

[leknyzma]

kid in the background feels the regex :D

[yogibarista]

A regex for email address that meets all of the various RFCs that can apply, is basically so ridiculous as to be impossible.
