Tuples in C# 7.0 look kinda interesting.

Per this you may have something like this wherein (string, string) is a ValueTuple of string, string.

public (string, string) LookupName(long id)
{
   return ("John", "Doe");
}

 
 

The input variable for id obviously does nothing, right? Anyhow, an example of an assignment from the same blog posting is:

ValueTuple<string, string> c = LookupName(0);

 
 

A ValueTuple is mutable! Also, an assignment, not to a tuple, but to two variables would look like so and this trick is referred to as deconstruction.

(string first, string last) = LookupName(0);
