.NET Interactive - how to change collection output size

Question

I'm using .NET Interactive notebook inside VS Code and want to change the number of printed out elements:

var x = Enumerable.Range(0,21);
x.Display();

Only first 20 element are shown in the the output:

enter image description here

Can I somehow increase the size of output?

if you change 0 to 1 you will see it works fine, but with 0 it does not takes the last one, for me is also question why?! — Hadi R., Apr 22 '22 at 17:03
@HadiR. `var x = Enumerable.Range(1,21)` still results for me in only 20 elements being printed. Just the last printed one is changed from 19 to 20 (while the actual last one is 21). — sup-team, Apr 22 '22 at 17:11

You can use Formatter from Microsoft.DotNet.Interactive.Formatting namespace to change the size of the output:

using Microsoft.DotNet.Interactive.Formatting; 
Formatter.ListExpansionLimit = 25;

Formatter.ListExpansionLimit = 20

Gets or sets the limit to the number of items that will be written out in detail from an IEnumerable sequence.
Formatter<T>.ListExpansionLimit = (not set)

An optional type-specific list expansion limit
