New Post: IServiceLocator inject at constructor VS ServiceLocator's static member?

Hi,

In my WPF, I could not use constructor injected because of my ViewModel already derrived from other class.

Then I modified the helper code to following by using FullName ServiceLocator.

public class AutoNotificationObject : NotificationObject
    {
        protected T Using() where T : class
        {
            var handler = ServiceLocator.Current.GetInstance<T>();
            if (handler == null)
            {
                throw new BusinessServicesException("Unable to resolve type with service locator: Type" + typeof(T).Name);
            }
            return handler;
        }
    }

var

handler = ServiceLocator.Current.GetInstance<T>()public AuthorizedController

(IServiceLocator serviceLocator)
        {
            this.serviceLocator = serviceLocator;
        }

What differnt between the two
