I think we should stay with the console app. It's simple, plus it's easy to focus on what you're learning. A UI only slows the process because half the time you're fighting with the controls and other things that are just not necessary. And I would rather spend more time on the things I want to learn.

And now I have something to throw back at you There really is no need to have the UI/DataGrid in this lesson. As long as I understand the mechanisms behind the UI implementation, I can always learn the UI parts later on. But I'm guessing that you've already put some time in already working with the DataGrid (and maybe even having fun), so if you want to keep that as part of the project, that's ok with me.

We could have dueling DataGrids

edit: I already know how to refresh the DataGrid so it shows the information you just inserted or updated. Plus I have alternating colors on my rows already.
