With the release of StructureMap4 it appears that the ControllerConvention registration class requires a minor update. This is how I have changed it, not sure if this is the best way to go: ``` public void ScanTypes(TypeSet types, Registry registry) { types.AllTypes().ForEach(type => { if (type.CanBeCastTo<Controller>() && !type.IsAbstract) { registry.For(type).LifecycleIs(new UniquePerRequestLifecycle()); } }); } ```
