container.register_transient(SomeInterface, SomeClass)
container.register_scoped(AnotherInterface, AnotherClass)
container.register_singleton(ThirdInterface, ThirdClass)

# Resolve dependencies
transient_instance = container.resolve(SomeInterface)
scoped_instance = container.resolve(AnotherInterface, scope_name="http_request_scope_123")
singleton_instance = container.resolve(ThirdInterface)
