how to import and call .Net DeviceInformation.FindAllAsync from ironpython?

Does anyone know how to import and access Windows.Devices.Enumeration.DeviceInformation.FindAllAsync() from IronPython?

I have some C# code targeting .Net 4.5 on Win8.1 that I'm trying to port to Iron Python, example:

C# snippet:

using Windows.Devices.Enumeration;

DeviceInformationCollection devices= await DeviceInformation.FindAllAsync( /* removed */ );

However, I just can't seem to import the 'Windows' assembly.

clr.AddReference("Windows")

results in:

IOError: System.IO.IOException: Could not add reference to assembly Windows

Does anyone know a way?

Here's my full test case (updated in light of some comments):

import clr

clr.AddReference("System.Windows")
clr.AddReference("System.Linq")
clr.AddReference("System.Runtime")
clr.AddReference("System.Runtime.WindowsRuntime")
clr.AddReference("System.Runtime.InteropServices.WindowsRuntime")

print  clr.References

import System
from System.Runtime import *
from System.Runtime.InteropServices.WindowsRuntime import *
import Windows


Windows.Devices.Enumeration.DeviceInformation.FindAllAsync()

Output:

so naively tried it out, I'm not even sure IronPython can import .winmd files, or of the resulting error is a permissions or missing dependency problem:

import clr
import sys
sys.path.append(r"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1\ExtensionSDKs\Microsoft.VCLibs\12.0\References\CommonConfiguration\neutral")
sys.path.append(r"C:\Program Files (x86)\Windows Kits\8.1\References\CommonConfiguration\Neutral")
clr.AddReferenceToFile("platform.winmd")
clr.AddReferenceToFile("Windows.winmd")

output:

SystemError: Operation is not supported. (Exception from HRESULT: 0x80131515)
