Powershell - persist variable outside of function

Question

I'm trying to import an xml file and store as a variable for the remainder of a powershell session. The import is obviously successful but the variable content does not persist outside of the function.

Function auth
{
$cred = import-clixml -Path c:\temp\cred.xml
}

Answer 1

try this:

Function auth
{
    $global:cred = "test"
}

auth
$global:cred
