RSRP-288634: Missing code completion option: List to List

I have the following code:

            var elements = new List<>();
            foreach (var element in parameter.Array)
            {
                elements.Add(new );
            }
            argument.ArrayElements = elements.ToArray();

There are of course errors (see print screen) but what I thought Resharper was supposed to do when I stand on the last line was give the option to change the type of elements to the type specified in argument.ArrayElements.
But it was missing. I got a tooltip but no actions available.
If I changed the code to:
var elements = new List<int>();
Then I got the option to change the elements list to the right type.


The scenario:
I wanted to create a list of elements but didn't remember the type of the elements so decided to leave it blank for now (and let Resharper do the work;)).
For the same reason I was stuck on elements.Add(new );
On the last line I was sure Resharper will give the option to change the type of elements but it was missing.


I am using Build 6.1.44.78
