Orderby syntax ASC

• .OrderBy(x => x.City) for ascending order.
• .OrderByDescending(x => x.City) for descending order

Use this query when you use Distinct.

var result = ctx.tblCity.AsNoTracking()
 .Where(s => s.City== "Chennai")                                 
 .Select(s => new Area { Name = s.AreaName})                                 
 .Distinct().OrderBy(s => s.Name).ToList();

It worked for me.
