Learn what LINQ is, how to define a query expression, and how LINQ makes it easy to query any data source. In doing so, Scott and David explore declarative programming and deferred execution.

Microsoft be like:
"How am I going to teach them about data structures without calling it a data structures leason...🤔"
Yours teaching method is outstanding!
it does not working List scores = [97, 92, 81, 60]; only work like
List scores = new List { 97, 92, 81, 60 };
Kind of off the subject. What kind of mouse is that?
A kind of ergonomic mouse.
An amazingly clear explanation that shows how simple LINQ can be at least for beginners like me. I've watched other videos and none of them make a clear distinction between query syntax and method syntax.

Why do they use the word "simpler" to mean "more complicated"?

LINQ look like a resource consumer one
I've used C and C++. This LINQ is new to me. But I've also done db queries. Does it matter if from/where/select are in that order? The reason I ask is it would look like a db query if it was select/from/where.
2:16 i have the latest version of visual studio code and the sdk 8.0 but it give me error if i try to List scores = [... it says not available in c#11 plz use 12 or greater, even though i updated sdk to version 8.0 and restart my machine many times, how it is working with u and not working with me, because later it effect the sorting thing int[] scores .... doesnt have sort property. so when u upload lesson just make sure its available in the market, not just for u
Is your project targeting .NET 8 as well?
i dont have project am just following up with ur video step by step, thanks for ur replay@@davidfowl
@@risechess7114 Find solution?
no not yet@@DataScientist268
create a project like they told in the beginning lectures inside the project folder you can see a .csproj file in it set targetframework to 8 (net8.0) (btw this needs dotnet 8 to be installed to work)
Is the IEnumerable a copy of the list or is it a list of links to the original data? Just wondering from a memory stand point and what happens if there are changes to the original list.
It’s an interface. It just specifies the required method names a data structure implementing that interface need. As a byproduct of that, LINQ will work with any implementation. Your question relates more to the individual data structure implementations
After years away from writing code in a Windows app, I want to resurrect a 1990s-era Visual Basic desktop app and 'refactor' it in C#. These sessions show me that I can enjoy doing what I did back then in a much more efficient manner. I am also hoping to find sessions that demonstrate how to call Windows functions in the various DLLs that comprise Windows today, and save even more code writing.
This is straightforward in c#. Use System.Runtime.InteropServices. It should be noted that a good portion of the windows API already has .NET bindings, but it’s a good thing to understand nonetheless
Great video, love it
love these guys!
