MVC 3 beta + Dependency Resolver + Unity = got problem
- by drsim
Hi everyone. I'm tried to use Dependency Resolver with Unity, and got some problem when my Controller creating.
Here example of controller:
public class AccountController : Controller
{
private readonly ICourseService _courseService;
public AccountController(ICourseService courseService)
{
_courseService = courseService;
}
}
But, when Controller try to create - i got an exception "No parameterless constructor defined for this object." I even try to add default constructor for this controller, but courseService didn't create. Also try to add property with [Dependency] attribute - nothing happened.
Here is Dependency Resolver class:
public class UnityDependencyResolver : IDependencyResolver
{
private readonly IUnityContainer _container;
public UnityDependencyResolver(IUnityContainer container)
{
_container = container;
}
public object GetService(Type serviceType)
{
return _container.IsRegistered(serviceType) ? _container.Resolve(serviceType) : null;
}
public IEnumerable<object> GetServices(Type serviceType)
{
return _container.IsRegistered(serviceType) ? _container.ResolveAll(serviceType) : new List<object>();
}
}
and Global.asax.cs:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
var container = new UnityContainer();
container.RegisterType<ICourseService, CourseService>();
DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}
Can anyone help me ?
