Hi Guys, I'm trying to create a .Net 4.5 class library in C# with VS 2013. I want to use the class WMI Win32_NetworkAdapter which is in the namespace Windows.Networking.Connectivity. But when I try to add a reference to the required assembly - Windows.Networking.DLL - I cannot do so. It does not appear in the list of available assemblies. I use Windows 7 Please let me know how can do that?
