Do I have to declare variables public to use [Dependency] with Unity?

Question

using Microsoft.Practices.Unity;   
..
..
public class ContentsController : BaseController
{
    [Dependency]
    public IContentService contentService { get; set; }

}

I am using Unity to give me an instance of IContentService. However it will only work if I declare this to be public. If I declare private then it _cs is null?

Is the only way I can get this to work by declaring it public ?

Can I declare the IContentService in the controller constructor? If I did that then can someone show me the best syntax and how I would connect this up to a private variable?

There is allready answer here: Unity framework DependencyAttribute only works for public properties? You have to declare variables public to make this attribute work as you expect it to.

As for the part about constructor injection:

public class ContentsController : BaseController
{
  private readonly IContentService service;
  public ContentsController(IContentService service)
  {
    if(service == null) throw new ArgumentNullException("service");
    this.service = service;
  }
}

var container = new UnityContainer();
container.RegisterType<IContentService, MyContentService>();
var controller = container.Resolve<ContentsController>();
