Bug: Error when trying to insert to Geography column using IPropertyHandler

[Simon-Carr]

Bug Description

Error when trying to insert to Geography column using IPropertyHandler.

1. I have verified that the lat/lng being passed are correct and valid.
2. The Set method in the property handler is hit when debugging and returns a valid looking SqlGeographyobject.
3. The Get method in the property handler works fine.
4. I am able to use lat/lng manually by inserting the values into float columns and then updating the Geography column from those directly:

UPDATE leads.lead
SET geolocation=geography::Point(lat, lng, 4326)
WHERE LeadId=146893;

Exception Message:

System.InvalidCastException: Failed to convert parameter value from a SqlGeography to a String.

Schema and Model:

It's just a single Geography column, other columns are unrelated,

The insert looks like this:

 await cnn.InsertAsync(dto,
                cancellationToken: cancellationToken, transaction: transaction);

the dto is rather long, but the relevant column looks like this:

 [PropertyHandler(typeof(GeographyPropertyHandler))]
    public CoordinatesDto Geolocation { get; set; }

And this is the handler

public class GeographyPropertyHandler : IPropertyHandler<SqlGeography, CoordinatesDto>
{
    public CoordinatesDto Get(SqlGeography input, PropertyHandlerGetOptions options)
    {
        return new CoordinatesDto
        {
            Longitude = (decimal)input.Long.Value,
            Latitude = (decimal)input.Lat.Value
        };
    }

    public SqlGeography Set(CoordinatesDto input, PropertyHandlerSetOptions options)
    {
        return SqlGeography.Point((double)input.Latitude, (double)input.Longitude, 4326);
    }
}
