Answer 1

While I realize that this is an old question, the answers didn't resolve my issue with EF 6.

For EF 6 you need to create a ComplexTypeConfiguration Mapping.

example:

public class Workload
{
    public int Id { get; set; }
    public int ContractId { get; set; }
    public WorkloadStatus Status {get; set; }
    public Configruation Configuration { get; set; }
}
public class Configuration
{
    public int Timeout { get; set; }
    public bool SaveResults { get; set; }
    public int UnmappedProperty { get; set; }
}

public class WorkloadMap : System.Data.Entity.ModelConfiguration.EntityTypeConfiguration<Workload>
{
    public WorkloadMap()
    {
         ToTable("Workload");
         HasKey(x => x.Id);
    }
}
// Here This is where we mange the Configuration
public class ConfigurationMap : ComplexTypeConfiguration<Configuration>
{
    ConfigurationMap()
    {
       Property(x => x.TimeOut).HasColumnName("TimeOut");
       Ignore(x => x.UnmappedProperty);
    }
}

If your Context is loading configurations manually you need to add the new ComplexMap, if your using the FromAssembly overload it'll be picked up with the rest of the configuration objects.
