Mastering Ninject for Dependency Injection

Summary

We studied the most common DI patterns and antipatterns related to Ninject. Multibinding means binding a single service type to multiple concrete types and has two scenarios of the Plugin model and contextual binding. Providers are a kind of factories that are specialized for Ninject to be used for creating new instances of resolved types. We can create our own providers by deriving from the Provider<T> class. A Factory method is a substitute for Provider, where the activation logic is short and simple and instantiation of the service type is not as simple as calling the constructor of the implementation. Introducing a dependency as Lazy<dependency> informs Ninject to defer instantiation of that dependency whenever that dependency is requested. ...
