How it use DependencyResolver

The DependencyResolver provides two basic methods: Register and Resolve. Register allows to map abstractions to implementations at bootstrap time of an application. These registrations are sometimes also called services, service mappings or dependencies. Later, at runtime of the application, the Resolve method is used to create instances for the registered services.

// Create a new dependency injection container var resolver = new Resolver(); // Register dependencies resolver.Register<ILogger, ConsoleLogger>(); resolver.Register<IPaymentService, PaymentService>(); resolver.Register<IPaymentServiceConfiguration, PaymentServiceConfiguration>(); // Resolve dependencies var paymentService = resolver.Resolve<IPaymentService>(); paymentService.Charge(99m, new MasterCard());

Disclaimer

Do not use DependencyResolver in production code!<br/>Use one of the well-known DI frameworks instead: Autofac, Unity, Ninject.
