What's the difference between System.Tuple and (,)? [duplicate]

Question

Background: I am using two methods from different libraries; one uses System.Tuple<double,double> and the other uses (double,double) for arguments. I am finding myself unable to utilize both methods without doing extra work to convert a System.Tuple to a (,).

What is the difference between System.Tuple<t1,t2> and (t1,t2)?

Answer 1

(t1,t2) is a ValueTuple<,> not a Tuple<,>

So doing the following will work:

ValueTuple<int, int> hey = (1, 2);

However, this will give you a type error

 Tuple<int, int> hey = (1, 2);
