Using inefficient methods First()/Last() on LinkedList<T> CS-P1024

The methods First() and Last() come from the Enumerable interface defined in System.Linq. While they may be appropriate for other structures and scenarios, they are not performant for LinkedList<T>. Consider using LinkedList<T>'s own properties First and Last as they're efficient and tailored for this very purpose.

Bad Practice

var first = list.First();

Recommended

var first = list.First;
