Compatibility

The following table show which version of this library to use with which version of EF Core.

Usage

Enable DateOnly and TimeOnly support by calling UseDateOnlyTimeOnly inside UseSqlServer. UseSqlServer is is typically called inside Startup.ConfigureServices or OnConfiguring of your DbContext type.

options.UseSqlServer(
 connectionString,
 x => x.UseDateOnlyTimeOnly());

Add DateOnly and TimeOnly properties to your entity types. Or reverse engineer a table with date and time columns.

class EventSchedule
{
 public int Id { get; set; }
 public DateOnly StartDate { get; set; }
 public TimeOnly TimeOfDay { get; set; }
}

Insert data.

dbContext.Add(new EventSchedule { StartDate = new DateOnly(2022, 12, 24), TimeOfDay = new TimeOnly(12, 00) });
dbContext.SaveChanges();

Query.

var eventsOfTheDay = from e in dbContext.EventSchedules
 where e.StartDate == new DateOnly(2022, 10, 12)
 select e;
