Why do I get “Database already exists” when I'm using “AttachDbFileName” when I move the solution to another directory?

Question

I have an application JigSaw that uses a database TopScores.mdf which it is not included in the project. What I want to do is make the application find the database

Answer 1

change setting in your connection string from "Database=TopScores.mdf" to something different, say: "Database=TopScores_brand_new_connection" do not create/delete/rename files in any file/database server. do it in the connection string only. Do not add dots, extensions etc.
