I have a very simple ASP.net application that I use to learn. I developed it (two controls - a drop-down list and datagrid, as well as an EF class) on my laptop using a copy of production db (this initial application is read-only), so I can minimize the variables that I need to understand when I deploying a much more secure environment on my client.
