Lets consider some cases:
_windsor.Register(Component.For<IProductServices>().ImplementedBy<ProductServices>().Interceptors(typeof(SomeInterceptorType));
In this case, when I ask for a IProductServices windsor will proxy the
interface to intercept the
interface method calls.
If instead I do this :
_windsor.Register(Component.For<ProductServices>().Interceptors(typeof(SomeInterceptorType));
then I cant ask for windsor to resolve IProductServices, instead I ask for ProductServices and it will return a dynamic subclass that will intercept virtual method calls.
Of course the dynamic subclass still implements 'IProductServices'
My question is : Can I register the
Interface component like the first case, and get the subclass proxy like in the second case?.
There are two reasons for me wanting this:
1 - Because the code that is going to resolve cannot know about the ProductServices class, only about the IProductServices
interface.
2 - Because some event invocations that pass the sender as a parameter, will pass the ProductServices object, and in the first case this object is a field on the dynamic proxy, not the real object returned by windsor. Let me give an example of how this can complicate things : Lets say I have a custom collection that does something when their items notify a property change:
private void ItemChanged(object sender, PropertyChangedEventArgs e)
{
int senderIndex = IndexOf(sender);
SomeActionOnItemIndex(senderIndex);
}
This code will fail if I added an
interface proxy, because the sender will be the field in the
interface proxy and the IndexOf(sender) will return -1.
