Refactor CreateNoteService

  1. Open ElevenNote.Web -> Controllers -> NoteController

  2. Click and drag down the button at the top right corner of the window so it splits the code into 2 sections. This is so you can see things at the top and bottom of the file at the same time.

  3. Notice that the same 2 lines are repeated

  4. Select this code in the Create method

  5. Go to Edit -> Refactor -> Extract Method

  6. Rename the new helper method CreateNoteService()

  7. Change NoteService to var

  8. Notice how it abstracts out the code so that it is usable in all ActionResult methods

  9. TIP: Do not try to instantiate a Service inside of the constructor. The MVC framework does not have the data available that may be needed.

Next, we'll add some validation messages.
