Is there an elegant way to implement the following in a ActionFilterAttribute
.
_provider = new DetailsProvider(new DetailsService(new CachingService()))
As you can see this does not look good. What I want to get away from, is 'newing' up these concrete classes.
Is there a nice alternative?
I solved this using
public HandlerAttribute() :
this(DependencyResolver.Current.GetService<IDetailsProvider>()) { }
public HandlerAttribute(IDetailsProvider detailsProvider)
{
_detailsProvider = detailsProvider;
}
I am using SimpleInjector but this is interchangeable as I am using a Resolver.
You can just use whatever containers, get instance of concrete class using interface method.
