context has changed since the database was created

I am getting this error when I run my MVC3 application:

The model backing the 'MoviesDB' context has changed since the database was created. Either manually delete/update the databas开发者_运维技巧e, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the DropCreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data.

I am using EF 4.1. Please suggest solution.

Looks like you added an entry in the either in the Movie model or in the database. Make sure that the schema matches and delete the EdmMetadata table.
