In the above example, dependencies on the concrete class and interface will resolve an instance of class ExampleClass. A dependency registered by super type will automatically be registered by concrete type. In the above example, dependencies on the concrete class and interface will resolve an instance of class ExampleClass. A dependency registered by super type will automatically be registered by concrete type.
If you want to prevent registrations from being both registered by interface and concrete type, use the "doNotAddConcreteTypeRegistration" option when registering:
```d
dependencies.register!(ExampleInterface, ExampleClass)([RegistrationOptions.doNotAddConcreteTypeRegistration]);

It is also possible to register a type while resolving it. Doing so means you don't need to explicitly register it beforehand. To do this, use the resolve option "registerBeforeResolving": It is also possible to register a type while resolving it. Doing so means you don't need to explicitly register it beforehand.
