Adding Other Endpoints

Previous: Introducing an In-Memory Database

In this section, we'll be building out three more endpoints, GetAsync(long id), PostAsync(Note note) and DeleteAsync(long id).

In NotesController, the GetAsync(long id) method should be annotated with [Route("{id}", Name = "GetNoteById")]. The Name attribute will be used to reference the endpoint in the PostAsync endpoint.

For the success case in PostAsync of NotesController, return a CreatedAtRouteResult using:
```
CreatedAtRoute("GetNoteById", new { id = processedNote.Id }, processedNote)
```
This makes reference to the GetAsync(long id) endpoint that we annotated earlier, and passes the arguments required via an anonymous dictionary, as well as the Note itself for the body of the response.
The response from PostAsync(Note note) has a RouteValues member that contains all the values from the anonymous dictionary passed to CreatedAtRoute.
Remember to annotate your method parameter on PostAsync(Note note) with [FromBody].
When the PostAsync(Note note) endpoint and AddNoteAsync methods have been added and tested, they can be used in repository tests to replace calls to _context.Notes.Add(note) with await _repository.AddNoteAsync(note).
