This is a known and documented breaking change.
from breakingchanges.txt
change - Proxies no longer implicitly implement all interfaces of
component implementation type.
impact - medium
fixability - medium
description - This original behavior was actually a bug and would
produce unpredictible behavior
for components exposing several services including their class.
fix - if you were depending on the additional non-service intrfaces
being forwarded to the proxy
specify them explicitly as addtional interfaces to proxy:
container.Register(Component.For<CountingInterceptor>()
.Named("a"),
Component.For<ICommon>()
.ImplementedBy<TwoInterfacesImpl>()
.Interceptors("a")
.Proxy.AdditionalInterfaces(typeof(ICommon2))
.LifeStyle.Transient);
cheers,

Hi
In Windsor 2.5.3, the code below worked fine, however in Windsor 3.0
RC1 this throws the following exception:
Unable to cast object of type 'Castle.Proxies.IMyServiceProxy' to type
'IService'.
Is this a change in 3.0 ??
TIA
