Implement Dependencies in User Membership

Question

I have an ASP.NET MVC3 project where I want to use a custom membership provider. I also want to use Unity to solve my dependency injection.

This is the code from Global.asax:

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);

        var container = new UnityContainer();
        container.RegisterType<IAuthentification, Authentification>();
        container.RegisterType<IRepository, Repository>();

        DependencyResolver.SetResolver(new UnityDependencyResolver(container));

    }

this is the code of my membership provider:

public class CustomMembershipProvider : MembershipProvider
{
   [Dependency]
   private IProveaRepository Repository { get; set; }

   public override bool ValidateUser(string username, string password)
    {
       .....
    }

The problem is that when I set a breakpoint on the ValidateUser method, I see that the Repository property is not initialized. But this design:

   [Dependency]
   private IProveaRepository Repository { get; set; }

for example, works great in controllers.

Does anyone know why this is so and what to do?

. ( ). ​​

public class CustomMembershipProvider : MembershipProvider       
{
    private IProveaRepository repository;

    public CustomMembershipProvider() 
        : this (DependencyResolver.Current.GetService<IProveaRepository>())
    { }

    public CustomMembershipProvider(IProveaRepository repository)
    {
        this.repository= repository;
    }

    public override bool ValidateUser(string username, string password)
    {
        ...
    }
}
