with your help my knowledge is better now. This week, I would like to try something more. Because I'm working on 2 computers, I use One Drive for Business for syncing. So I can take my laptop without Internet connection and continue to work.
So, in my idea, the main goal is to have the database on Visual Studio solution (so it will be synced back to the desktop computer when I returns). I'm not sure, in Visual Studio 2015, in the Server Explorer windows, I see sometimes a MDF file or a DBO.
Because I'm making tests, I will add fields to tables often. With the SofiaRental sample, we have a SQL file to generate the database. Then, in my case, what is the building steps of database from scratch and how to update C# mapping to new fields ?
