Powershell Remoting: using imported module cmdlets in a remote pssession

Question

Is there a way to use modules that were imported in a local session in a remote session? I looked at import-pssession, but I don't know how to get the local session. Here's a sample of what I want to do.

import-module .\MyModule\MyModule.ps1
$session = new-pssession -computerName RemoteComputer
invoke-command -session $session -scriptblock { Use-CmdletFromMyModule }

Also, I do not want to import-module in the remote session, as the ps1 files are not on that server.

Answer 1

I ended up hacking this to work. What I did was create a local session, import modules into that session and used import-pssession to import modules from the created local session into the remote session. This is slow. If anyone has a better way of doing this, or if someone knows how to get an instance of the base session I'd love to hear from you!

Remoting.psm1

function Export-ModuleToSession {
 Param(
  [ValidateNotNull()]
  $session,
  [ValidateNotNull()]
  $modules
 )

 $computername = $env:computername

 $modulesToImport = get-module -name $modules

 invoke-command -session $session -argumentlist @($computername, $modulesToImport) -scriptblock {
  Param(
   $computername,
   $modules
  )

  write-host ("Creating Temp Session On: " + $computername)

  $localSession = New-psSession -computername $computername

  $modules | foreach-object {
   if($_.ModuleType -ne "Binary") {
    $path = $_.path
   }
   else {
    $path = join-path (split-path $_.Path) ("{0}.psd1" -f $_.name)
   }

   invoke-command -session $localSession -argumentList $path -scriptblock {
    Param(
     $path
    )

    $initializeDefaultBTSDrive = $false
    set-executionpolicy unrestricted

    write-host ("Importing Module To Temp Session: " + $path)
    import-module $path
   }
  }

  $initializeDefaultBTSDrive = $false

  $modules | foreach-object { 
   write-host ("Exporting Module: " + $_.name)
   import-psSession -session $localSession -Module $_.name  | out-null 
  }
 }
}

MyModule.psm1

function MyCmdlet {}

RemotingTest.ps1

import-module .\remoting.psm1
import-module .\MyModule.psm1

try
{
 $remoteSession = New-PsSession -computerName "RemoteComputer"
 Export-ModuleToSession -session $remoteSession -modules "MyModule"

 Invoke-Command -session $remoteSession -scriptblock { MyCmdlet } -verbose -ea Stop
}
finally
{
 Remove-PsSession $remoteSession -ea Continue
 Remove-Module "Remoting" -ea Continue
 Remove-Module "MyModule" -ea Continue
}
