LINQ has been around for sixteen years already. That means it's been here forever. And still, some C# programmers have trouble seeing the place LINQ should take in their designs. That place exists. LINQ is more than just a fancy syntax that takes the loops and ifs away.
In this video, we are putting LINQ in the context of an application that accepts data from a data source and deserializes them into objects and collections or sequences of objects. That is the setup in which LINQ takes over when it comes to processing sequences of objects and applying the domain rules to them.
By clearly separating the data and the iterator on one side and specifications and strategies on the other, LINQ naturally comes in between, where it can bridge the gap between the definitions of objects and transformations.

👨 About Me 👨
Hi, I’m Zoran, I have more than 20 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017 I have started publishing professional video courses at Pluralsight and Udemy, and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my CZcams channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️

Impressive!
You went very smoothly from LINQ being just a "tool" for operating on data to functional programming.
It's very helpful to look at LINQ this way because indeed it is a powerful fundament of specification pattern 🚀
Amazing channel. It's really nice to see our people on youtube.
Zoki srecna Nova! Da si mi ziv i zdrav! i ove godine da odradis prvu knjigu na srpskom i engleskom jeziku! Za stampariju cemo se snaci :) Ziveli i svako dobro! 🍺🍻🍺
I love your expressive voice ! Keep it up!
Hey! At 4:22 you mention "Watch that video..." - is there a link for it somewhere? Thanks. 👍🏻
I will add those links to the description, too. In the meanwhile, it should have popped up in the upper right corner during playback.
Thank you 😊 (they show up on Android, but not if using Chromecast to my TV).
Pozdrav Zorane. Vaš kurs, Functional C# 10 na Pluralsightu je jedini kojem treba premium subscription. Ostale sam uredno gledao sa basic. Je li to greška ili je to tako zamišljeno?
Hvala.
Ne znam kako Pluralsight organizuje članarinu, ovo je nova informacija za mene.
@@zoran-horvat Nisam siguran kako izaberu koji ulaze u basic a koji u premium. Baš šteta. Ne znam kako je sa vaše strane, ali što se korisnika tiče, lakše je x puta na udemy-u. Platiš kurs koji te zanima i doviđenja.
U svakom slučaju hvala na odgovoru, genijalan kontent snimate.
Where can i get your course for functional programming C#
My latest course on functional C# is published at Pluralsight: codinghelmet.com/go/functional-csharp
The Linq problem now is how to support IAsyncEnumerable in the same way as for usual IEnumerable. Yes, there are extensions already that help to use async/await inside and it is enough in many cases but not always. I use Linq forever and do not use loops at all but how about await foreach {} loop in Linq and so on?
IAsyncEnumerable is covering a very narrow corner case. I am not sure how important LINQ would be there, let alone that many of the traditional LINQ operators are not even applicable to asynchronous sequences.
@zoran-horvat select and selectmany are trivial to custom implement for it, using yield syntax
You can also make overloads of selectmany to make it work seamlessly with ienumerable and task, which makes the query syntax a really expressive notation
- Where have all the patterns gone?
- The girls have picked them, every one😊
I thought of adding that to the video but didn't know how to make it look right :)
@@zoran-horvat You have good taste in music Zoran).
Perhaps a musical insert without words, just a melody). But I’m not a video editing specialist and I don’t know how difficult it is to do in terms of time spent.
