async wrapper is somehow not working for me.

Hi!

I am trying to wrap the reading of the CSV file with async/await but the application still seems to freeze while reading the file. Here is the code that I have:

      public class CsvUtility
      {
          //public static async Task<SomeModel> ReadCsvFile(string filePath)
          public static List<SomeModel> ReadCsvFile(string filePath)
          {
                  var mapModelToReturn = new List<SomeModel>();
  
                  using (var reader = new StreamReader(filePath))
                  using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
                  {
                      csv.Read();
                      csv.ReadHeader();
                      //while (await csv.ReadAsync())
                      while (csv.Read())
                      {
                          if (String.IsNullOrEmpty(csv.Parser.Record.FirstOrDefault()))
                              break;
  
                          var newModel = csv.GetRecord<SomeModel>();
                          mapModelToReturn.Add(newModel);
                      }
                  }
                  return mapModelToReturn;
          }
      }

and I call that method with

var modelToUse = await Task.Run(() => CsvUtility.ReadCsvFile(fileLocationString));

I did test with "await Task.Delay(10000)" to make sure that the async/await wrapper is working and not freezing the application. It seems to only freeze when I use the above code for CsvReader. I have tried using "ReadAsync" as can be seen in the commented out lines of code but still freezes the application until reading is complete. Any help is appreciated! thanks!
