How to prevent EF4.1 from creating a DB if it doesn't exist?
I'm using EF4.1 with MVC3 and I need an override to prevent EF from creating a db if it doesn't exist. Instead of creating a new db I would like to catch the error and report that the initial catalog (the database name) is invalid in the connect string.

However, during development I would like to allow for updates for new classes/properties to create according tables/cols in the database.  

Is there a best practice or pattern here?
