ExecuteAsync
In .ASP.NET Web API, what is a controller?
A class that handles HTTP requests. The public methods of the controller are called action methods or actions.
How is a Web API route formatted?
api/controller/possible something here
Why does api have to be in the route for Web API?
To avoid possible collision with ASP.NET MVC
When receiving a request, how does Web API find the correct action using naming conventions?
To find the action, Web API looks at the HTTP verb, and then looks for an action whose name begins with that HTTP verb name. For example, with a GET request, Web API looks for an action prefixed with “Get”, such as “GetContact” or “GetAllContacts”. This convention applies only to GET, POST, PUT, DELETE, HEAD, OPTIONS, and PATCH verbs.
In WebAPI, what is an alternative to naming conventions to find the correct action?
Use an attribute with an HTTP verb such as [HttpGet]
Can you have multiple http verbs on a controller or custom verbs?
Yes, using AcceptVerbs and that’s all you know about that. Ex: [AcceptVerbs(“GET”, “HEAD”)]
