How to map to destination with less properties than source in Automapper 6?

I am trying to write mapping configuration for next case. I have domain object:

public class Category
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string ImagePath { get; set; }

    public virtual ICollection<Service> Services { get; set; }
    public int? SubcategoryId { get; set; }
    [ForeignKey("SubcategoryId")]
    public virtual Category Subcategory { get; set; }
}

And Dto to map:

public class CategoryDto
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string ImagePath { get; set; }
}

The problem is, target class have less properties, than source. If I use simple map, I get an exception.

Mapper.Initialize(n => n.CreateMap<Service, ServiceDto>());

I can't use Ignore(), because it will be applied to target class, not source one. Method ForSourceMember() also didn't help for some reason. I read this question, it's fine for most cases, but property Services is not null, it's Count = 0, when it's empty. I also read some similar questions from the right, but they didn't help, maybe they worked in previous versions.

Hope someone can help me to find solution, or explain what I missed.

Mapper.Initialize can only be called once, when your app initializes itself, not per request as you're doing now.
