From your example (i.e. placing DateTime.Now into a const) ... are you intending to save the compile timestamp into the executable code? What would be the intent? It would be pretty close (if not exactly the same) as the file date of the EXE/DLL.
Only idea I could think for this to be used is to check if the executing file has been altered since it was compiled. Though for that I'd rather use some hash value instead, even just CRC would be more comprehensive than a timestamp.
To me, the readonly idea makes more sense - i.e. it would save the time the program was started.
This is the true difference between const and readonly: Const is as if the compiler changes your code to as if you typed in a literal value. Readonly is a way to make sure a variable only gets assigned its value once - from any calculation at runtime. The two ideas are not interchangeable, at least not in most cases.

These are probably a good idea. Though semantic-wise I'd actually want it to be a readonly instead. In C++ const is used to give the compiler a hint so it knows this parameter wont get changed inside the function, so a copy of it need not go onto its stack (just a direct memory link instead). But even there I'd actually want to rename it to something like readonly instead, const just confuses the hell out of me (is it only a param calculated at compile time, why then not just a normal const in the first place and do away with the param entirely?)

Here you may be onto something. I'd imagine getting something like this working at present would be a form of making automatic struct types for each property - incorporating their default properties with a get set as defined in code. Perhaps including it into the spec could be done more efficiently.
It should definitely not be enforced though. In some cases the rest of the class does need to see the underlying data without needing to go through the accessor methods. Which in turn brings up another issue in C# ... the inability to have default properties like you can in VB-Net. In C# your closest match is to make implicit type-casting operator overloads.

iOS 11 can automatically delete apps to save space - The Verge[^]
Quote: the Offload feature removes little-used apps, but keeps their documents and data on your device.
Will this really save much space? Do you have many apps that are big in file size? It doesn't seem like it would help much.
Why is storage space still an issue in 2017?
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

Because their market segmentation strategy uses storage size as a way to scam people out of a disproportionate amount of money .. which makes it even stranger that they want to save space, if anything they should want to waste it.

Apps likely not the real issue, more likely iOS's own bloat. And to be fair it's a pattern of all OS's.
These days "updates" tend to be as large (sometimes even larger) than the original and always need a ton of temp space to install whatever storage you have will always be a premium.

It's only a premium when storage space is running low. Why is storage space such an issue these days? The capacity to make bigger and larger storage is there.

Absolutely. Maps can be well into the Gb size, as can graphics/asset heavy games.
It's also not about individual size: if you happen to be a hoarder then 100 apps each at 100Mb will be 10Gb, right? That's harsh if you've only been able to afford a 16Gb version of the phone.
cheers

But I wonder if the OS will consider the maps to be data and leave them behind, assuming they are separate resource files and not embedded.
Chris Maunder wrote: then 100 apps each at 100Mb
I don't even have one app that comes close to 100 MB. I guess I'm doing it wrong.

I'm sure everything would be backed up to iCloud. For a small administrative fee, of course.

You're lucky. Over half my apps are over 100Mb. Just getting over that line are things like The Weather Network App (seriously: it just needs to display info from a webservice!) and our local parking meter app. 101Mb to pay for my parking. Crazy considering Outlook is "merely" 106Mb.

It's only an issue when your phone doesn't have a MicroSD slot.

My understanding (as someone who's never owned one, and never will) is that yes, not a single iPhone has ever included a MicroSD slot. Meaning that if you're afraid you're gonna run out of room one day, you're gonna spend more upfront to get the larger-capacity one.
It's a feature. For Apple.

Like continuing to push out new Windows Phone updates regularly, even though the platform has long been declared dead? Whereas you'll be lucky to get one OS update throughout an Android device's lifetime?

Compare and contrast...
My Lumia 640 phone came with Windows 8.1. It got upgraded to 10, and to this day I can still install Insider updates on an almost weekly basis if so I choose.
My cheap-ass HP Stream 7 tablet came with 8.0 (I think), and again, was trivial to update to 8.1, then 10, then to all releases of Windows 10 that came between that and the Creators Update from last March.
My first-gen Surface Pro tablet is also now on Creators Update.
Now for the fun part:
I have 4 Android tablets; an ancient one that came with Android 2.2, another that came with 4.2, another that came with 4.3, and finally, another with 6.0. Only the one that came with 4.3 had an upgrade to 4.4 (which in hindsight was pretty minor), and that's it. More often than not, I can't install apps anywhere because "...your device is not compatible with this version of Android".
In my experience, Android tablets are pretty much abandonware the moment you walk out the store, and based on stories I keep reading about carriers not making OS updates available, Android phones aren't doing any better. I'm hoping I'm not ever going to be foolish enough to believe I could buy another Android device and assume it's one day going to be upgradable.
Oh, and Cyanogen is pretty much dead at this point.
Wanna buy some Android tablets? All barely used, all in great condition.
Does this answer your " "?

Because an iPhone with 128 Gb costs way more than 16 Gb, so you are focusing it wrong. It is not a technical question, it is economical.
Coming back to the feature... I find it a bad feature if you can't set a "don't touch this ever" list. Only because I don't use something that much doesn't mean it is not important when I do need it.

I could have read it wrong but it does look like you can enable the feature per app if you want to.
