问题 We start a Powershell function via Start-Job and want to retrieve its output in the caller in real time.

With that said: Suppose I have a module with a function that would look like this mock: function Set-ComputerTestConfig { [CmdletBinding()] param( [Parameter(Position=0, Mandatory=$true)] [ValidateNotNullOrEmpty()] [string] $Name) begin { ... } process { # task 1 # task 2 => results in a failure that
