The entry point and the flesh of a service are controllers. While handlers are one of the initial classes in the ASP.NET Core pipeline, once the request has passed through ASP.NET and has found an appropriate route, it will be directed to your controller.
Now you are in control of what data you want to send as your response. A controller can contain many methods. Although these may be public methods, not all of them will be available. Enabling HTTP actions on these methods will turn these methods into actions.
In the course of this chapter, you will get a better understanding of controllers and how they tie in with the ASP.NET pipeline. We will create some controllers as well as the actions for these controllers.
In this chapter, we will cover the following topics:
- Introduction to Controllers
- Actions
- Creating Controllers with models
