En ajoutant à ce que Kev a dit...

Si vous utilisez csc.exe au lieu de Visual Studio, pour ajouter une référence à Windows Script Host Object Model, vous devez:

• Utiliser le tlbimp.exe outil pour créer un assembly géré:

  tlbimp.exe c:\windows\system32\wshom.ocx /out:IWshRuntimeLibrary.dll

• De référence de l' .dll à l'aide du commutateur /r en csc.exe:

  csc.exe Lnk.cs /r:IWshRuntimeLibrary.dll
