Yep! Also, I got round to watching "Floor Is Lava" (on Netflix) last night. Oh dear!  That will be my first and last episode. It's not just poor. It's incredibly irritating! The only way they could make it worth watching is to replace the bubbly red water, with actual real lava!

I'm busy changing part of our codebase to use the new style of using statements: What's new in C# 8.0 - C# Guide | Microsoft Docs
It's nice because it's neater and causes less nesting, but for someone not familiar with it the drawback is that it's less understandable than the classic syntax. What are your opinions on syntax changes like this?
Also, should I pay back the company for the lines of deleted code? :P

I assume you can still use the "old" way also. That syntax is fine if, like the example, you code would otherwise be;
private void MyFunction()
{
using (var x = new Widget())
{
}
}
as you are reducing the inner nest, but for all other uses (pun not intended) the existing way should defo be used. What you'll see though is people using the new way regardless because if it is "new" it must be "better"  "Why do you want to change this for loop to a linq statement again....?"

Being honest, I haven't use the new one. But looking at the examples of MS that you linked is not that bad, but if a function is more complex and needs a couple of usings that can get a bit messed up if the dispose is only called at the very end of the function instead of being called when exiting the "active" using.
Have you tested it in such scenario?

My scenario was mostly adding tracing to a method. So with the old syntax I could either add the braces or for less nesting have a finally where I dispose the tracer.
The other places where I changed it I don't think it matters too much bc that part was at the end of the method. If it were at the start it might make a difference.

Then just saving one indentation index is not worth the lose of readability or the mess of the execution scopes. At least in my opinion

Code is written primarily for other programmers, not for the compiler. It does not matter how elegant your code is, if others cannot understand it.
Jacquers wrote: What are your opinions on syntax changes like this?
If it isn't broken and is properly written, don't fix it. If you are fixing broken code, rewriting poorly written code, or writing new code, you may consider using new syntax.
Personally, I believe that the chance of introducing bugs into formerly working code by such syntactic sugar is not worth the supposed increase in clarity. My opinion might differ if you are writing a completely new module.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

I don't like it: I don't think it's as obvious what the precise scope of the variable is and where it gets disposed.
For me, it gets "swallowed" by the other code and is harder to work with.
It's a bit like "always use curly braces" even when you don't really have to - they can save a lot of grief when you do this:
if (a == b)
c;
d; And don't notice.

This. Oh, so much this.
To me the curly braces remove all ambiguity and they tell me exactly what the original coder had in mind. Without any brace, could the disposable variable be disposed of earlier than the end of the function? Probably. Where? I don't know, and now I have to study the code more closely to determine that. This syntax is trying to tell me it shouldn't matter to me. And I disagree with that.

Anyone and everyone that is writing production code (vs, say, hobby code for yourself and to learn) should know the syntax of the language like the back of their hand. One may not choose to use a particular syntactical sugar, but it should NOT result in a "WTF does this mean?"
Conversely, we all start from a place of "not knowing" and that's fine. But any code a junior dev writes should be reviewed by the senior people and the junior person should be educated. It's better for them, it's better for the company and the code base.
For example, I still feel I write "hobby level Javascript" and when I have to touch something on the front-end for our product, I always ask my coworker who knows Javascript much much better than I to review my changes.
I also look at his commits to learn things!
Writing dumbed down code simply so it's more readable for the less educated - why? That's absurd.

Hell no. They should pay you! Less code == less things that can go wrong.

One would assume so. But we don't write code for the compiler, unless we're writing highly optimized kernel code, IMO. We right code so we can read it later.

I have seen it too often that cosmetic changes/refactorings have brought errors into the software. Ok, you can argue now that our tests were bad.

I'd argue the tests were valid and the refactoring caused the problems. The new code failed regression testing.

I'm blaming Resharper for that. It knows about the latest and greatest syntax "improvements" (ahem), and won't shut up until you make it happy.
While it's a useful tool, I've always found it to be a memory hog, and VS is always doing more than its fair share of that. So I don't use it. But one of my coworkers keeps it up to date, and is a big believer in compiling clean (0 error, 0 warning).
But I definitely remember one instance where Resharper made a suggestion that had implications that broke code elsewhere. I know I'm too busy to make changes for the sake of making changes.

I use the newest language constructs wherever I can.
Mostly because Visual Studio draws a small squiggly line and advises me to change it to the latest standards (and even does it for me).
I do like them though, less nesting, less variables (like with the inline out parameters), etc.
I'm not going to revisit old code unless I have to though.
Don't fix what isn't broken and all that.

Since productivity is measuered in LOC/day, your productivity is currently negative.
..but I agree with the others - don't "fix" it; every edit might introduce a new bug and the changes are NOT an improvement that yields enough result to justify spending the time on it. Economically, it always costs more than it yields.
I'd argue that you'd be better of playing a game.

Just remember that usings are disposed in the reverse order of their declaration. If you have function scoped disposable variables then this new syntax is really nice as it avoids unnecessary code block nesting. If, however, you need to dispose the object as soon as it's released, then use the traditional syntax.
