Problem with AbstractMethodError

[João Gonçalo Guimarães Correia]

Hi,

Im trying to extract pdf data with solrnet client. I code is the following:

using (MemoryStream stream = new 
MemoryStream((byte[])dataReader["file_stream"]))
                    {
                        var solr = 
ServiceLocator.Current.GetInstance<ISolrOperations<Contribution>>();
                        ExtractParameters extract = new 
ExtractParameters(stream, "doc1", dataReader["nome_original"] + "")
                        {
                            ExtractOnly = true,
                            ExtractFormat = ExtractFormat.Text/*,
                            StreamType = "application/pdf"*/
                        };
                        var response = solr.Extract(extract);
                        Debug.WriteLine("\n+++++++++++++++++++++++++++++++ " + 
response.Content);
                    }

However Im getting the error you can see below:
