Iâ€™d like to use .Net Core (Console App) and EF Core to create my business logic, a number crunching engine that loads financial data from a local database (MySQL or SQLite), process it, will store the results in the same database and show them to the user.
I want to be able to easily add in the future a GUI to manage the CRUD operations and simple commands.
How can I implement the MVVM pattern in a console application to be able to easily add a GUI in the future (Win7-10 and MacOs)?
Representing a view model on the command line sound like a natural mismatch. There are engines for drawing views using the terminal, however, in my opinion you should target the command line not with a mvvm pattern. MVC where the view is the console and the controller received the command line sounds like a better fit.
