Yeah, well - all of you can get off my lawn! I was conceived on the evening of the day when the Western Allies crossed the Rhine, according to my mother. The interesting thing is that my father, an officer in the Royal Corps of Signals working in a bunker deep below London, knew about it a day before the the life forms living above ground...

We had .NET Core 3.1, then .NET 5 (which was the next version of .NET Core 3.1, skipping "4" so as not to confuse people with .NET 4.x, gee, thanks) and now we have .NET 6, aka .NET Core 6.
enum CoreVersion
{
DotNetCore31,
Net5,
Net6,
WhatsCore,
WhoCares
}
var you = Programmer.Factory();
if (you.AreUsing(".NET") && you.AreUsing("Core"))
{
CoreVersion version = you.WhichDoYouUse();
Console.WriteLine(version);
}
? How's that for a survey question?
One thing that is driving me nuts about .NET 6 is the null checks. Absurdly invasive.
Yes, the whole null check madness can be disabled in the .csproj by setting <Nullable>enable</Nullable> to <Nullable>disable</Nullable>
At least we have that option, otherwise it's:
#pragma warning disable CS8714 // The type cannot be used as type parameter in the generic type or method. Nullability of type argument doesn't match 'notnull' constraint.
#pragma warning disable CS8602 // Dereference of a possibly null reference.
#pragma warning disable CS8600 // Converting null literal or possible null value to non-nullable type.
#pragma warning disable CS8618 // Non-nullable field must contain a non-null value when exiting constructor. Consider declaring as nullable.
And who knows how many other pragmas.

Yeah the whole "reference types are nullable" -> "reference types need to be made explicitly nullable" seems like a "oops, we didn't think of that" backtracking in philosophy. Or may the tech is simply at the point where the tooling can now help offset the inconvenience so it's no longer an inconveniece.
I get what they are trying to achieve, but what I generally end up doing is just making my ref types nullable and then, later, checking whether they are null or not. Back to square 1. The static type checking and the errors if you don't do the null ref check are nice, though.

I dabbled with the nullable types when they were first introduced, but I have no real use for them.
I actively avoid new "features" unless they provide a real benefit. Even Extension Methods are really just a "nice-to-have". Though I find Anonymous Methods to be very useful, particularly for making threads.

I find nullable types really useful when the class is a model of the DB table schema, but otherwise agreed. I do like the idea of string? to properly reflect a column string type that is nullable.

Quote: .NET 6, aka .NET Core 6
I think they ended .NET Core line with .NET 5; bringing it all (Core, Standard, Framework, etc. etc.) together in a single platform.
Personally, I'd like a .NET version that doesn't have a lifespan of 2-3 years only. I stopped caring about .NET versions, to be honest.

They ended the core branding with .NET 5; but .NET 5 is still .net core; not .net framework.

Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I like .NET6
Null checks are a fine way to prevent some silly error.. granted they might seem annoying occasionally, but you can then use the ! operator like so: string s = null!;, go ahead, try it!

At this point I have no idea which .NET version is which or even which I'm using at any given time.

Well, I'm definitely not doing upgrades - my curiosity is for new personal projects. I've been using .NET Core 3.1 and have been recently poking at .NET 6. So far so good, but again, these are greenfield projects, not upgrades.

I see no reason to keep using .net Core 3.1. .Net 6 is LTS, can be used with the same good old syntax and has wider compatibility with other OSes. Also, they fixed quite a few bugs in the runtime libraries - but I guess one could use the most recent NuGets with older runtime versions.
We have both .net webforms (4.8) apps and razor (6.0) apps sharing the same logic libraries, so in those we use multitargeting and reference NetStandard where possible. If only MS made EF6 compatible with .net standard 2.1 we could get rid of multitargeting altogether (EF Core is not a valid alternative for our use cases).
We are also exploring how to replace Windows-specific dependencies with portable ones, mostly because from our preliminary tests running unit tests under Linux seems to be much faster.
One thing I really cannot stand: the new main syntax (Should the console project template use top-level statements · Issue #27420 · dotnet/docs · GitHub[^]). Maybe I'm just getting old

It sure takes a bit getting used to, at least visually. I was quite taken aback when I started with a .NET 6 Web API template. Where's Startup.cs? WTF is going on in Program.cs?
Once I realized what happened, my brain started to slowly adjust -- but it's still adjusting.

My personal motto is not to stick to previous versions unless there's a REALLY good reason to use them. To name an example, .NET source generators still require a .NET standard project, so I'm running mine on .NET standard instead of upgrading it to .NET 6.
The null checks are great! I've enabled them in .NET 5 (where they were optional) and am very glad they're enabled by default now. Having the null as a conscious & explicit construct, rather than something which just happens & is kept implicit, is a huge boon for safety!
Knowing for sure that a string parameter (as opposed to a string? parameter) will not be null (and it it is, I'll get an exception way before control flow forks into this particular method) helps a lot!
I also came to use null explicitly if I want an erroneous value which doesn't warrant an exception. When, an example I often work with, parsing a protocol with optional fields, I initialize those fields to null in the output structure. Knowing that the only way for a null to get there is for my parser to put it there because null is explicit.

This is why I am nervous about crypto. Are there any old school banks with years of protecting electronic accounts that will hold crypto for you? For a fee, of course!

The banks put the controls in place, the consumer keeps looking for "bridges" so they won't have to think, etc.
