Re: Inserting to database
Did you add the DataBase as a DataSource in your project? If so, you can click on it in the DataSource Viewer and change it's CopyToOutputFolder property to never.
Re: Inserting to database
I think circuits meant to select your database file in the Solution Explorer, then open the Properties window and set Copy To Output Folder property. Also, I'd recommend setting it to Copy If Newer. That way if you make any changes to your original database then a new copy will be created in your output folder and you'll start using the new schema immediately.
