Powershell - appelant tombe en panne CreateProfile non géré Fonction Powershell.exe

Question

Lorsque vous appelez un morceau non géré de code avec pinvoke-createprofile. Le processus Powershell.exe se bloque après l'appel à la méthode dans le code non managé. Le profil est créé avec succès.

Pourquoi se passerait-il? Mon code est ci-dessous:

function CreateProfile 
    { 
     param([String]$UserSid, [String]$UserName, [system.uint32]$ProfilePath) 
     Add-Type -TypeDefinition ' 
      using System; 
      using System.Runtime.InteropServices; 
      public static class PInvoke { 
       [DllImport("userenv.dll", SetLastError = true, CharSet = CharSet.Auto)] 
       public static extern int CreateProfile([MarshalAs(UnmanagedType.LPWStr)] String pszUserSid, [MarshalAs(UnmanagedType.LPWStr)] String pszUserName, [Out][MarshalAs(UnmanagedType.LPWStr)] System.Text.StringBuilder pszProfilePath, uint cchProfilePath); 
      } 
     ' 
     $pszProfilePath = new-object -typename System.Text.StringBuilder 
    [int]$results = [PInvoke]::CreateProfile($UserSid, $UserName, $pszProfilePath, $ProfilePath) 
    } 
$stringbuff = new-object system.text.stringbuilder(260) 
[system.uint32]$a =$stringbuff.capacity 
$sid = ((get-aduser -id 'brtestlocaluser').sid.value) 
CreateProfile -usersid $sid -username 'brtestlocaluser' -ProfilePath $a

Enfin a été en mesure de comprendre cela. L'appeler dans un autre moyen semblait résoudre ce problème.
