Hi folks.

First some background:

container.ResolveAll<IFoo>();

if you call this method in current version of Windsor (and v2.1 and 2.0 and RC3 too I think) it will resolve all components where implementation type implements IFoo. That's not what most people would expect, which is - to return only components that were registered to expose IFoo as their service.

in other words:

container.ResolveAll<object>() will resolve each and every component from the container.


Now, that's not usually a big deal and I guess some people even depend on this behaviour. However it breaks horribly in ASP.NET MVC where Controller class implements all four kinds of filter interfaces and it's a mess if you want to nicely pull filters from the container.

It also is not the default that most people would expect so:

*I want to change that behaviour in vNext so that it returns only components exposing IFoo as a service.*

Notice that you will be able to make it behave like it does now with a custom IHandlersFilter (added few weeks back) which will have additional benefit of being more fine grained so it doesn't have to be an all-or-nothing thing.

Any insights/objections?
