Definition IsFirstRowAsColunmNames not existing in the IExcelDataReader of the reference ExcelDataReader

Using Visual Studio 2017, I installed reference packages through Nuget

• ExcelDataReader
• EcxelDataReader.DataSet version 3.4.0

I'm following a tutorial on how to open XLS file and this one giving error in the following line, I would like to know how to solve this error.

The line that is giving error is this in the code below:

reader.IsFirstRowAsColunmNames = true;

It says it does not contain this definition in IExcelDataReader

I'm using the following using below

• using ExcelDataReader;
• using System;
• using System.Data;
• using System.IO;

• using System.Windows.Forms;

  private void btnOpen_Click(object sender, EventArgs e)
  {
      DataSet result;
  
      using (OpenFileDialog ofd = new OpenFileDialog() {Filter="Excel Workbook *.xls", ValidateNames = true })
      {
          if(ofd.ShowDialog() == DialogResult.OK)
          {
              FileStream fs = File.Open(ofd.FileName, FileMode.Open, FileAccess.Read);
              IExcelDataReader reader = ExcelReaderFactory.CreateBinaryReader(fs);
              reader.IsFirstRowAsColunmNames = true;
              result = reader.AsDataSet();
              cbbPlanilha.Items.Clear();
  
              foreach (DataTable dt in result.Tables)
              {
                  cbbPlanilha.Items.Add(dt.TableName);
              }
  
              reader.Close();
          }
      }
  }
