You can use the NodaTime library FromJulianDayNumber method to do the conversion to an instant from which you can get UTC, it will handle all of the minutia that the accepted answer does not handle.

Create this extension method:

public static class DoubleExtensions
{
    public static DateTime JulianDateToUtc(this double julianDate)
    {
        var sinceEpoch = julianDate - 2440587.500000D;

        return new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddDays(sinceEpoch);
    }
}

Then you can just do:

2458324.500000D.JulianDateToUtc();
