PSCredential.Empty.GetNetworkCredential() throws NRE instead of returning null per docs #4696
Description
Steps to reproduce
> [pscredential]::Empty.GetNetworkCredential()Expected behavior
$null
Per the docs, an "uninitialized" PSCredential object should return null
MSDN also documents it as such, though only on the page of the explicit cast operator which just calls GetNetworkCredential
Actual behavior
Exception calling "GetNetworkCredential" with "0" argument(s): "Object reference not set to an instance of an object."
