DateOnly Converter & Comparer for Entity Framework Core 6.0

DateOnlyConverter.cs

public class DateOnlyConverter : ValueConverter<DateOnly, DateTime>
{
    public DateOnlyConverter() : base(
            dateOnly => dateOnly.ToDateTime(TimeOnly.MinValue),
            dateTime => DateOnly.FromDateTime(dateTime))
    {
    }
}

public class DateOnlyComparer : ValueComparer<DateOnly>
{
    public DateOnlyComparer() : base(
        (d1, d2) => d1.DayNumber == d2.DayNumber,
        d => d.GetHashCode())
    {
    }
}

Hello.
What is the ValueComparer for?
I read there is a problem with change tracker when only the DateOnly typed property is changed.
Has it anything to do with it?
Thanks.

Yes, ValueCompararer is used for the ChangeTracker, as you can read here: https://docs.microsoft.com/en-us/ef/core/modeling/value-comparers?tabs=ef5

That's a quick response. Thank you.
I'm reading it right now.
