Output data not automatically mapping non-specified fields

[adamzuckerman]

I have a model class:

public class QueryResults
{
  public double Distance { get; set; }
  public string StreetLine1 { get; set; }
  public string StreetLine2 { get; set; }
  public string City { get; set; }
  public string State { get; set; }
}

In my data access layer, one of the methods maps some of the model's fields.

var mappings = new ColumnMappingCollection();

// Start defining the mappings between each property/column for a type
mappings.RegisterType<QueryResults>()
  .MapProperty(x => x.Distance).ToColumn("distance")
  .MapProperty(x => x.StreetLine1).ToColumn("street1")
  .MapProperty(x => x.StreetLine2).ToColumn("street2");

mappings.RegisterWithDapper();

string query = "SELECT distance, " +
  "sites.street1, " +
  "sites.street2,  " +
  "sites.city, " +
  "sites.state, " +
  "FROM mytable ";

// Execute my query using Dapper 
IEnumerable<QueryResults> results = connection.Query<QueryResults>(query);

The results returned by the query do not include the unmapped properties/fields. Specifically, the City and State fields do not get populated.
