I need a simple, single page website with a small form to signup for a newsletter.
The form has only 3 fields, there is no server backend, so it must store/retrieve data from a simple SQLite database.
When you fill the form and click "Signup", it stores your info in the SQLite Database.
If the e-mail is already registered, returns a message saying it's already registered and date.
Must de done using ASP.NET Core, with MvC Pattern.
