Deep Dive on LINQ with Stephen Toub

Рет қаралды 53,145

Күн бұрын

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.

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.

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 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.

@ripvannwinkler 2 ай бұрын

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.

@TheChonsey 2 ай бұрын

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.

This kinda feels like the KZfaq 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.

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.

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.

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.
