[Mansuri Shahrukh]

I am using below code for it and its give an error that Error The type or namespace name 'SolrField' could not be found (are you missing a using directive or an assembly reference?)

 public class TrackInfo {

            [SolrField("id")]

            public string Id { get; set; }

            [SolrField("Title")]

            public string Name { get; set; }

            public IDictionary<string, object> OtherFields { get; set; }

                               }

        }

    }

}

please give a solution for it .
