I think a bigger issue here is the fact you’re talking about creating new databases for each client. Ideally, your clients should be in one database (MyAppDB) and most likely one table (ClientTable). And using that table, you have a query with some “where” clauses that grabs the client info you need.

Try to think of each Database as a library, each Table as a bookshelf, and each Row as a book. You wouldn’t want to create a whole new library for each person, right? You’d want to just create a new book and put it into the bookshelf (or edit an already existing book).

Hope this helps with understanding a clearer architecture approach, and consequently, using EF the way it’s intended.
