Network Interface does not contain a definition for ""

Question

I recently created this code for a WPF application that I was doing. The project where I'm reusing the code is a Windows 8 application. The code itself is the same so I don't really see what could be the issue. The only difference between them is of course the application and the .NET Framework being used. In the WPF application I was targeting .NET 3.0 and for the Windows 8 application I'm using .NET 4.5.

As you can tell this is an extension method:

public static bool isTunnel(this NetworkInterface adapter)
        {
            return adapter.NetworkInterfaceType == NetworkInterfaceType.Tunnel;
        }

The error it gives for that method is:

Error   3   'System.Net.NetworkInformation.NetworkInterface' does not contain a definition for 'NetworkInterfaceType' and no extension method 'NetworkInterfaceType' accepting a first argument of type 'System.Net.NetworkInformation.NetworkInterface' could be found (are you missing a using directive or an assembly reference?)

Error   4   The name 'NetworkInterfaceType' does not exist in the current context

In my model class I'm having a similar issue. On this line:

foreach (NetworkInterface adapter in NetworkInterface.GetAllNetworkInterfaces())

it causes an error saying that the GetAllNetworkInterfaces() does not exist in NetworkInterface. Here's the exact error:

Error   15  'System.Net.NetworkInformation.NetworkInterface' does not contain a definition for 'GetAllNetworkInterfaces'

Is there something that I don't know about reusing code from WPF application in Windows 8 applications?

Update: Using the ianainterfacetype I was able to fix half of my extension methods because I was able to tell if they were Ethernet, Wireless, or Tunnel. I'm still searching for a way to tell if they were created by VirtualBox or VMware.

For those who want to know about the ianainterfacetype you can find info here.

GetAllNetworkInterfaces is not available to Windows Store (metro) apps. The MSDN Documentation indicates that only the GetIsNetworkAvailable method is available to Windows Store apps. The green briefcase indicates whether or not it is available to Windows Store apps.

I am not aware of any API that is available to Windows Store apps that can give you the information you are looking for.
