Configure and use AutoMapper in ASP.Net Framwork API

I am trying to use AutoMapper in Asp.Net Framework API (not core) and when I try to use, my model DTO gets all attributes null.

I tried a lot of solutions and a lots are deprecated. So, my actual solution is:

1. Create a Configuration class

public static class AutoMapperConfig
{
    public static IMapper _mapper { get; set; }

    public static void Register()
    {
        var mapperConfig = new MapperConfiguration(
            config => 
            {
                config.AddProfile<MyProfile>();
            }
        );

        _mapper = mapperConfig.CreateMapper();
    }

}

2. Load at the start in Global.asax

protected void Application_Start()
{
    ...
    AutoMapperConfig.RegisterMapping();
}

3. Take model from .edmx and create a DTO

public class User
{
    public string Name { get; set; }
    public string Surname { get; set; }
    public string Address { get; set; }
    ...
    public string Email { get; set; }
}

public class UserDto
{
    //I need only this 3
    public string Name { get; set; }
    public string Surname { get; set; }
    public string Email { get; set; }
}

4. Create a Profile

public class MyProfile : Profile
{
    public MyProfile()
    {
        CreateMap<User, UserDto>().ReverseMap();
    }
}

5. Use AutoMapper in a Controller

public class MyController : ApiController
{
    readonly IMapper mapper = AutoMapperConfig._mapper;

    public List<UserDto> Get()
    {
        using(var ctx = new DbEntities())
        {
            var src = ctx.User.ToList;
            var dst = new List<UserDto>();
            src.ForEach(u = > dst.Add(mapper.Map<UserDto>(u)));
        }
    }
}

Now, for some kind of reason, I get all object in dst List null. For example, I have 3 object in DB and when I call this method I retrive 3 DTO objects but with all params null. Why?

Thanks
