Whats ResolveAll do

Question

In the IOC, what does ResolveAll do ?? I know that the official answer is "Allow all active components matching this type." Does this mean that it will return any class that implements this interface?

Answer 1

It will return all classes registered for this interface.

... and do not wait for any links to be resolved. This is a bit of me today!

Answer 2

With Unity, ResolveAll allows each registered mapping for an interface other than the default mapping.

therefore, if you are registered:

 container.RegisterType<IInterface, ActualClassOne>(new ContainerControlledLifetimeManager()); container.RegisterType<IInterface, ActualClassOne>("Singleton", new ContainerControlledLifetimeManager()); container.RegisterType<IInterface, ActualClassOne>("Trans", new TransientLifetimeManager()); 

ResolveAll () will only give you IEnumerable containing the allowed "Singleton" and "Trans" mappings

Answer 3

It will return all classes that have been registered for this interface.

Answer 4

If I have:

container.ResolveAll (new {argument = something}). Where (...)

it seems that all T components get an instance with "something", although not all components fill in the where clause .... who cares about releasing these additional components?
