The next step is to make a list of month names. We’ll use LINQ to generate a list of months, with the current month set as the default value.

 public IActionResult Index()
        {
          var GetMonth =  Enumerable.Range(1,12)
                .Select(m => new SelectListItem
                {
                    Text = new DateTimeFormatInfo().GetAbbreviatedMonthName(m),
                    Value = m.ToString()
                }).ToList();
                       
            ViewBag.Month = GetMonth; 
            return View();
        }
