Yeap, that's how the interceptors work
first is the first to execute the code before proceed, and last the
execute code after proceed.
So they work like onions (or orgres)

Thanks, it worked.
public IInterceptor[] SelectInterceptors(Type type, MethodInfo method,
IInterceptor[] interceptors)
{
var _new = interceptors.OrderBy(i => i is ValidationInterceptor ? 0 :
1).ToArray();
return _new;
}
Then, I'd to change my interceptors a little bit, each one now calls Proceed
before doing anything else. This way ValidationInterceptor proceeds to
NotifierInterceptor, which in turn proceed to real code, then
NotifierInterceptor does what it have to do and eventually
ValidationInterceptor (which can throw exceptions).
Will pay attention whenever I put a new interceptor, to not affect the others.
Thanks again.

Hi!
I'm creating proxies this way:
public static T Build<T>() where T : class, new()
{
var notifierInterceptor = new NotifierInterceptor();
var validationInterceptor = new ValidationInterceptor();
var proxy =
_generator.CreateClassProxy<T>(validationInterceptor,
notifierInterceptor);
return proxy;
}
I've found that, when validationInterceptor executes and throws an
error, the other interceptor doesn't gets a chance to run. I've tried
to reverse the order that they're passed to method:
var proxy =
_generator.CreateClassProxy<T>(notifierInterceptor,
validationInterceptor);
But same thing, validationInterceptor always runs first.
What can I do to handle that?
Thanks
