First will never return null - it throws an exception if the item cannot be found.
FirstOrDefault however may return null.
I have seen coworkers do:
var x = y.First(x => false);
if (x == null) {
...
}
and it would be valuable to hint to them that they are either using the wrong method (should be using FirstOrDefault) or writing dead code.
