Description: PR Summary Updates the hashtable type inference so it falls back to type inference if the value of a safe expression evaluates to null (for example if a variable hasn't been assigned in the session yet) $UnassignedVar = Get-ChildItem $Hashtable = @{ Key1 = $UnassignedVar } $Hashtable.Key1. Also updates the member expression type inference to retrieve members from PSSyntheticTypeNames, allowing this: $MyObject = [pscustomobject]@{ Key1 = Get-ChildItem } $MyObject.Key1. to work as expected.
