'STATUS_INTERNAL_ERROR: Unknown error in injected C++ completion routine. (Code: 41811968)'

Super simple console application injecting a dll and I get the above error:

   class Program
    {
        static string channelName;

        static void Main(string[] args)
        {
            var wow = Process.GetProcessesByName("WowClassic").FirstOrDefault();
            // Get the full path to the assembly we want to inject into the target process
            string injectionLibrary = Path.Combine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location), "TestLibrary.dll");
            EasyHook.RemoteHooking.IpcCreateServer<ServerInterface>(ref channelName, System.Runtime.Remoting.WellKnownObjectMode.Singleton);

            RemoteHooking.Inject(wow.Id, injectionLibrary, injectionLibrary, null);

            Console.WriteLine("<Press any key to exit>");
            Console.ResetColor();
            Console.ReadKey();
        }
    }

Any ideas?
