      Description

      Empty installation of http://downloads.mongodb.org/win32/mongodb-win32-x86_64-2008plus-ssl-3.4.0.zip on Windows 10 x64.

                  var clientSettings = new MongoClientSettings();
                  clientSettings.Server = new MongoServerAddress("localhost", 27340);
                  var server = new MongoServer(MongoServerSettings.FromClientSettings(clientSettings));
                  server.Connect();
                  var db = server.GetDatabase("admin");
                  var command = new CommandDocument("rolesInfo", 1);
                  db.RunCommand(command);
                  server.Disconnect();
      

      raises System.InvalidOperationException : Duplicate element name 'roles'.
      Previous versions of C# driver raise the same error.
      All versions work fine on Mongo 3.2, 3.0, 2.6.
