?. operator treats DBNull as null causing the methods to not execute #11084
Description
Since the implementation of ?. operator treats DBNull, NullString and AutomationNull as null, we cannot call any method on them using ?. operator. The concern is only for DBNull as for other types we truly consider them as null.
Steps to reproduce
[System.DBNull]::Value?.GetTypeCode()Expected behavior
DBNull
Actual behavior
null
