c# - What is the purpose of new() while declaration of a generic class? -

what purpose of new() while declaration of baseentitycollection class?
if i'm going remove it, got error following message "t must non-abstract type public parameterless constructor in order use parameter ..."

public abstract partial class baseentitycollection<t> :         list<t> t : baseentity, new() 

it means whatever class specify t, has default (no parameters) constructor.

therefore, in generic class, can new t() , create new object of type t.
