The IEnhancedStorageSilo.GetAction and GetPortableDevice methods always throw ERROR_INVALID_DATA

https://github.com/microsoft/Windows-classic-samples/blob/27ffb0811ca761741502feaefdb591aebf592193/Samples/Win7Samples/winbase/storage/EhStorManaged/microsoft.storage.EhStorage.dll/EhStorAPIInterop.cs#L108

When using this code to enumerate silos, the GetAction and GetPortableDevice methods consistently fail

public void EnumStorage()
{
   StorageACTEnumerator stores = new StorageACTEnumerator();
   for (int i = 0; i < stores.ACTCount; i++)
   {
      var store = stores.GetACT(i);
      foreach (var silo in store.silos)
      {
         foreach (var action in silo.siloActions) // <<== Exception thrown at GetActions
         {
         }
      }
   }
}

Open EhStorAPIInterop.cs at line 108 and reproduce the EnumStorage example, focusing on the siloActions enumeration where GetAction fails. Trace both GetAction and GetPortableDevice through the interop declarations and verify the behavior against the EhStorManaged sample; done means these methods no longer consistently return ERROR_INVALID_DATA during silo enumeration.
