When you add/modify some table in the production database, you have to update your application.

First thing to do is edit the web.config/app.config of the application, pointing the connection string to the production database (in your case, database in azure).

If you are using db-first, update the model from database.

If you are using code-first, it is better to make changes in your classes, and then update the database structure via data migrations. Otherwise, you might have some problems in the future updates, because the current database structure and the migration history will not match.

Update the application in the azure cloud service.
