Missing method exception in .net core

I think this may have something to do with the dependencies, but I'm not really sure.

So I'm trying to check to see if a TCP connection is still active using the extension method I found here, but I'm getting a missing method exception:

"Method not found: 'System.Net.IPEndPoint System.Net.NetworkInformation.TcpConnectionInformation.get_LocalEndPoint()'"

Which I'm a little confused on since the method seems to exist.

Here's the code: 

 public static TcpState GetState(this TcpClient tcpClient)
        {

                var status = IPGlobalProperties.GetIPGlobalProperties()
                                               .GetActiveTcpConnections()
                                               .SingleOrDefault(x => x.LocalEndPoint.Equals(tcpClient.Client.LocalEndPoint));

                return status != null ? status.State : TcpState.Unknown;

        }

and the JSON file where I think there might be a problem in how NetworkInformation is referenced: 

{
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true
  },
  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0"
        }
      },
      "imports": "dnxcore50"
    }
  },
  "dependencies": {
    "system.net.networkinformation": "4.0.10-beta-23123"

  },
  "version": "1.0.0-*"
}

Am I on the right track? How would I fix it?

Try adding system.net.security package also, as system.net.networkinformation depends on security package. It might not have loaded dependencies automatically.
