Exactly why I regretted using one about five minutes after I used one 
It's also my biggest problem with functional languages, what the hell do you have in your tuples!? (int, int) isn't telling me much... 
The only time a tuple did me any good was when my boss made fun of me for not having a formal education in IT.
He said something, I asked him "what's that?", and he was all like "haha, yeah you didn't get that in school, of course."
I was their top programmer at the time, and I think that bothered him as, indeed, unlike my coworkers I didn't have formal education.
So anyway, I did some Open University courses and I read about tuples.
In a next conversation with my boss I told him "it's just some tuple" and then he asked me "what's that?"... THAT'S PAYBACK TIME BIATCH!!!

Tuples are pointless in their current implementation. The size limit is completely arbitrary, and the work around for the size limit is absurd. You'd be better off with a static class that contains a List<object> property. At least that way, you could populate it with a virtually unlimited number of data items, of any type.
Of course, it doesn't have to be static, so if you want persistence, or a unique ObjTuple for given situations, it's easy to code it as needed. I provided the IsString methods to illustrate type-checking that you might want/need. It could be expanded to include all intrinsic types.
public static class ObjTuple
{
public static List<object> Objects { get; set; }
<pre>
public static void Create(params object[] parameters)
{
ObjTuple.Objects = (ObjTuple.Objects == null) ? new List<object>() : ObjTuple.Objects;
ObjTuple.Objects.Clear();
ObjTuple.Objects.AddRange(parameters);
}
private static bool InRange(int index)
{
return (index >= 0 && index < ObjTuple.Objects.Count);
}
public static bool IsString(int index)
{
return (ObjTuple.InRange(index) && ObjTuple.IsString(ObjTuple.Objects[index]));
}
public static bool IsString(object obj)
{
return (obj is string);
}
}</pre>
Usage would be something like this:
ObjTuple.Create("Test", 1, 5.1);
foreach(object obj in ObjTuple.Objects)
{
if (ObjTuple.IsString(obj))
{
}
}

Let's just hope you never have two threads trying to use that class at the same time.
And that you never need to call two methods that use it (or one method in a loop) and use the return value of both in the calling method.
And don't even think about using it in ASP.NET!

Everything you listed can be easily addressed, except ASP.NET. Nothing can fix that, because it's a web technology.

Angular 2 seems set to fix it, based on my recent self-tuition in that framework and the TypeScript language, which it is written in.

Seems a bit of overkill when you could just return List<object>. But hey that's just me.

A typed list, how pretensious, even if the type is object. In my appy days we used ArrayList.

Users of List<object> will pay a high price for the possible boxing/unboxing, or casting, or object Type inspection, that will occur ... or that will be necessary ... depending on the Types involved. And, the "opacity" of such code, like the current Item1 ... Item# syntax of .NET Tuples will, imho, make future code maintenance difficult.
Isn't this equivalent to using the old 'ArrayList structure ?

Just keep in mind that in .Net a Tuple is a reference type (class), not a struct.
|
|
|
|

In C# 7, the new Tuple, is a struct.

Well, that opens up fur some confusion.
Why don't they just call them anonymous return types instead?

And, that's one reason I have avoided them: [^].

Yes, I've read that. But that's a specific case.
If you read here[^] you'll find some performance comparisons.
You quickly realize that if you create, use and throw away, it makes sense to use a value type. But if your types are used more than once or twice before being destroyed, it makes sense to use reference types.

Hint 1: The Doctor's order?
Hint 2: How many times do I have to tell you? I do not like them!
Hint 3: All this puzzling is taking time,
So let's resolve it with a rhyme.

We have a winner!
It was, indeed, Green Eggs and Ham - an epic poem by the great Dr. Seuss in which the unnamed protagonist repeatedly refuses Sam-I-Am's offers of a dish of green eggs and ham in the firm conviction that the dish is not to his taste. SPOILER ALERT - needless to say, said unnamed protagonist eventually concedes and gives it a go, only to find that he actually does like green eggs and ham after all.
The hints were
1) The Doctor's order? What Doctor Seuss might have ordered in a restaurant.
2) I do not like them ... From the books's refrain - "I do not like green eggs and ham, I do not like them Sam-I-am!"
3) A Seuss-like rhyme pointing directly to the literary classic in question.
