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;
