How to use List with c# 8 Range?

Question

Hello,

I am trying to use c# Range features with List.
What am I missing to make it work?

int[] arrayTest = new int[] {1,2,3,4,5 };
int[] arrayRange = arrayTest[1..^2]; // Works!

List<int> listTest = new List<int>() {1,2,3,4,5 };
var listRange = listTest[1..^2];  // does not work.

 

Thanks!
