Like SQL, LINQ is an intention revealing/implementation hiding mechanism and as such has a valuable role to play in making C# development better.
However there is still a need to know how to do the implementation as you will need to use that when it comes down to it.

It's human nature to want to run before you can walk. Is that a bad thing? Not if it's the desire to run that makes you learn to walk but you still have to learn the two in the right order.
LINQ is definitely for one of the later chapters of the tutorial.
98.4% of statistics are made up on the spot.

how do I do that in VB6 ?

I think when Linq is best introduced/presented will depend on the student/trainee/audience background. Someone with depth SQL scripting and/or other language experience may get into it quickly.
For most folks, I think presenting iterative code examples together with Linq examples that do the same thing ... in increasing order of complexity ... is valuable.
I observe some students have difficulty with the "deferred evaluation" aspect of Linq. I like to use the metaphor of "creating a map," compared to actually following the map and bringing something back.
What's your favorite metaphor/mnemonic ?

I hate linq.
There. I said it.
I come across a bit of linq and I haven't got a clue what the heck it's doing. Even if it's code that I wrote.

Yet LINQ stands for Language Integrated Query, so it is effectively part of the language. LINQ can never replace C# - it isn't a language - and LINQ queries (for said novice) are written in C#. I do, however, agree about learning it later, when one can properly use standard chained method calls vs. the SQL like query format of LINQ.
I just think LINQ (especially LINQ to Objects vs. data access) is so terribly cool it's hard to stop oneself from wanting to just dive in. I did, as soon as it arrived, but fortunately I had close on five years C# experience and knew it well.

Linq is a good thought, but make the C# language less readable. If you write code that is difficult to maintain, you are creating more of a problem. Just because you can use the newest cool tool or idea, but your code and design requires more time for someone else to understand it, you are not doing a good job of engineering. Part of being a good engineer is to be sure that someone else can understand the design and code to quickly go on with it. Anything less is something anyone out of high school programmer can do.
To become a good engineer, you must know more than just programming (in any language). Design, documentation, system designing, requirements analysis, and asking the right questions to understand what the customer needs. Also, allowing for the next person to quickly be able to pick up the project and continue on.

...so, after rejecting their constant nagging to upgrade, I've finally been forcibly upgraded to the new Skype for Windows 10 (Desktop) ... what a pile of poo it is.
There is no way to change the font size. I thought accessibility was a priority in s/w design these days?
Nor is there any way to filter the contacts list (eg "Online only" or rearrange it in a different order. They are all there, listed by "Last used" and that's that.
I uninstalled it, but can no longer run an earlier version - I just get forcibly upgraded again.
For crying out loud, Microsoft, this is beyond bad.

Mickeysoft! They have been nagging me all day with some updates and I clicked it away with 'Do it tonight'. I have no time for that. Just a few minutes ago, not two hours later, it came up again. Now it graciously granted me another hour, but then there will be no way around doing the updates.
Which part of 'tonight' did you not understand, Mickeysoft?

You can turn Windows Update service off and you won't be annoyed again. There may be some scheduled tasks also, better have a look there too to be sure nothing will be executed without your consent.

Thanks. It's not my computer, so I keep my fingers away from the service. If I can keep that thing quiet another hour it will be time to head home anyway.
And kick me in the *** if I ever try to install this at home.

Add to that that if you're using Office 365, to share screens you have to start "Skype for Business" not the normal (as we say in the office now) "Skype for Pleasure".

As a single coutry you may have more people, but outside of Merka there are more people speaking proper English and spelling words with the U in them.
Merkan English is like Catholic Priest sex, an abomination and embarrassing.
