Desktop Application Dependency Injection with Unity

I've used unity with MVC Web App. and in MVC we there is app_start method. and we use

DependencyResolver.SetResolver(new UnityDependencyResolver(container));

and this send the parameters to the Controller Constructor. now i am trying to find how to implement this pattern to DesktopApplication.

u guys know that we use new Form1().Show(); //bla bla foo and when i create a new form is it possible to do when i created a new instance of type of System.Windows.Forms it automatically send the parameters to the constructor.

Sorry for my language. now i am using something like this and asking if it's a better solution:

public partial class frm_FirmaSecimi : XtraForm
{
    private IFirmaService _firmaService;

    public frm_FirmaSecimi()
    {
        InitializeComponent();
        _firmaService = UnityConfig.Container.Resolve<IFirmaService>();
    }
}

is there a way to turn this in to:

public partial class frm_FirmaSecimi : XtraForm
{
    private IFirmaService _firmaService;

    public frm_FirmaSecimi(IFirmaService firmaService)
    {
        InitializeComponent();
        _firmaService = firmaService;
    }
}

this is a DevExpress Form by the way. Thanx for answers.
