C# 从Azure SDK 2.5升级到Azure SDK2.8.1

我在运行时收到一个异常， 我该怎么做才能修好它

我把所有东西都升级到了最新版本

 var query = q as System.Data.Services.Client.DataServiceQuery<T>;
                    if (continuationToken != null)
                    {
                        query = query.AddQueryOption("NextPartitionKey", continuationToken.PartitionKey);
                        if (continuationToken.RowKey != null)
                        {
                            query = query.AddQueryOption("NextRowKey", continuationToken.RowKey);
                        }
                    }
                    // i fall here with the concrete exception I mentioned above
                    var response = (System.Data.Services.Client.QueryOperationResponse<T>) query.Execute();
                    result = result.Union(response.ToList<T>());
