When you are wanting to run code remotely, it’s common to do this via the use of Invoke-Command (though other options exist, such as through Start-Job for example). The biggest downfall to date i’ve found with remoting is the lack of an option to combine the use of your local functions within a ScriptBlock that has other code in it. As an example, the following is not possible:

function Add ($param1, $param2) { $param1 + $param2 } function Multiply($param1,$param2) { $param1 * $param2 } Invoke-Command -ComputerName $env:COMPUTERNAME -ScriptBlock { $addResult = Add $args[0] $args[1] $multiplyResult = Multiply $args[0] $args[1] Write-Output "The result of the addition was : $addResult" Write-Output "The result of the multiplication was : $multiplyResult" } -ArgumentList 3, 2 However, there is a way to achieve this type of operation, and make as many local functions as you want available to be used and combined with other code in your ScriptBlock.
