How do you use Autofac dependency injection?

The basic pattern for integrating Autofac into your application is:

  1. Structure your app with inversion of control (IoC) in mind.
  2. Add Autofac references.
  3. At application startup…
  4. Create a ContainerBuilder .
  5. Register components.
  6. Build the container and store it for later use.
  7. During application execution…

Why should I use Autofac?

Is Web API same as REST API?

Overview. A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services. REST stands for representational state transfer and was created by computer scientist Roy Fielding.

What is Autofac library?

¶ Autofac is an addictive IoC container for . NET. It manages the dependencies between classes so that applications stay easy to change as they grow in size and complexity. This is achieved by treating regular .

How does Autofac choose constructor?

Web service supports XML while API supports XML and JSON. All Web services are APIs but all APIs are not web services.

What are the downsides to using dependency injection?

Constructor Injection: is used to interface parameter that are exposed through the parameterized contractor.

  • Setter Injection: This is the most favoured method of dependency injection in Spring.
  • Interface-based Injection: This involves mapping items to inject to specific interfaces.
  • How to dispose resources with dependency injection?

    Avoid stateful,static classes and members. Avoid creating global state by designing apps to use singleton services instead.

  • Avoid direct instantiation of dependent classes within services. Direct instantiation couples the code to a particular implementation.
  • Make services small,well-factored,and easily tested.
  • What do you mean by dependency injection?

    Dependency injection. In software engineering, dependency injection is a technique in which an object receives other objects that it depends on, called dependencies. Typically, the receiving object is called a client and the passed-in (‘injected’) object is called a service. The code that passes the service to the client is called the injector.

    Why does one use dependency injection?

    Why do we use dependency injection? Dependency injection is a programming technique that makes a class independent of its dependencies. That enables you to replace dependencies without changing the class that uses them. It also reduces the risk that you have to change a class just because one of its dependencies changed.
