I just checked, and once I set my project to .NET 4.7.2 instead of 4.6.2 it compiled and worked perfectly:
private void FrmMain_Load(object sender, EventArgs e)
{
if ((ModifierKeys & Keys.Shift) == 0)
{
this.LoadLocation();
}
var loc = GetLocation("some address");
Console.WriteLine($"Lat: {loc.x}, Long: {loc.y}");
}
private (double x, double y) GetLocation(string address)
{
return (100, 100);
}

string interpolation != named tuples
(int First, int Last) intRage = (1,2);
like that.
Yeah, i think 4.7.2 might work. i'm installing now

The interpolation is just there for usage demo:
(int x, int y) v = (100, 200);
Console.WriteLine($"{v.x}, {v.y}");
Works fine as well.

ahh
well, it's not working in my .NET 4.7.1 target in VStudio. Only in .NET core 2.1+ target
which means it's using a newer version of the C# compiler

If its just two unnamed ints, return an array. If the two ints need names, create a class with two properties.
Will work with any framework.

There's lots of nested data. like this
(int Accept, ((char First, char Last)[] Ranges, int Destination)[] Transitions, int[] PossibleAccepts)[]
I'm avoiding polluting the namespace with types the end user-dev will never touch.
Most of these are strictly for parse tables - machine generated data that will never be touched by human hands, or perused by human eyes.
If I start polluting the namespace with types, I've in a way, broken encapsulation. Now, i can make these types private, but then if you ever WANT to see or debug or peruse these tables, you basically can't.
Tuples give me a really nice compromise. They avoid polluting the namespace, and are still exposed enough that someone can use them and alter them if they really want to.
Keep in mind, this is not a general guideline for writing code - this is a very special case.

It is language feature and not Framework related...
Using C# 7.0 you have tuples, using 7.1 you have named tuples...
All you need is to configure your project (the easiest way is to pick a framework compiles with those features by default, like 4.7.2)...

As you were tying that i did some research to find out which C# versions ship with which MS devstudio targeting packs.
And you're right, but i don't have those installed. Remedying now.

If you are using VS 2017, you can add named tuples via nuget: NuGet Gallery | System.ValueTuple 4.5.0[^]

it doesn't let the C# compiler use implicit naming though does it? that's a *language* feature that came AFTER c# 7.0. It's not a framework feature, although the ValueTuple type framework feature is usd by the compiler to support this.

Not sure - I'm using 2019 at the moment (I removed 2015 and 2017 when I installed the latest, just keeping 2013 in case ...)

I'm still on 2017, as i like to wait until many other devs have updated before i do.

I have to say it's been pretty stable so far - I've had fewer problems with it than with 2017 (which is why I didn't move to that or 2015). It's slower than 2013 to compile, but seems to load slightly faster.
And I like some of the UI addins such as "always visible" reference counts - even if some of the "improvements" it suggests are contradictory. Fuzzy searches are handy as well, as is Intellicode, when you get used to it (Intellisense on steroids).

I get refcounts in VS2017. The rest is new i think.
the reason i don't switch is it's harder for me to share code. not really a stability thing. A lot of devs are somewhat conservative about updating, so i try to hold off a little myself, so that we can exchange project files, like I can post them here and more people can use them without having to fiddle with recreating an older project file from the source code.

I know how you feel - I tend to wait as well, but 15 was so poor, and 17 was flaky - so I figured that I'd have to bite the bullet and move to 19. Not regretted it yet!

That's good to know. I've had luck with VS2017 for everything but VSIX projects. It stopped working after the first one i created so now if i want to make integrated "custom tools" i have to add them to that first VSIX i made!
i get some E_INVALIDARG message when I try to create a VSIX package anymore.

You can install 17 and 19 side by side on the same machine (provided 17 goes on first) so you could check if VSIX is working?

I could but frankly, i'm not into downloading all that right now.

adding, I keep VS2008 around for building VSTs. LOL. The newer c++ compilers do not like the old steinberg header code.

If you can't upgrade your project to .NET 4.7.2, you'll need to add a reference to the System.ValueTuple package:
NuGet Gallery | System.ValueTuple[^]
Looking at the dependencies, it claims to work as far back as .NET 4.5.

interesting, but i think this is a C# language feature. I need to use 7.1 or maybe 7.2
I was using nameless tuples before - using that reference you pointed out (already ships with .NET core 2.1)
It compiled fine.

My C# compiler insists otherwise
EDIT: Misread you. I am using implicitly named tuples
