VSCode , unable to resolve members intellisense , F# notebook

[unuunc]

Wrote following code and try to invoke intellisense:

open System
let y = new System.IO.DirectoryInfo("D:\work")
y.
it just show abc , I was expecting it to show all methods available.

this thing work fine when we try to use dotnet class , so if I do System. It get resolved. so the problem is with objects.
