Creating a new code first approach to the existing Database

Question

Hello Everyone, I have an application where my application was build-ed using Entity framework Code first approach and entities. Now I am creating a new application which should point to the same existing database, can I create my new application using code first approach with the existing database. In my new application, I am going to add only a few entities. Any help would be appreciated.

in EF code first approach where ever changes you do before updating it reflect in migration seed method so before updating you can modify your seed method where you can remove delete command of table and then update the database So it will not reflect the changes to the database

Notmapped attribute you can use on entity or property which will prohibit to get updated to database

Hi Chauhan, I am using the same entity classes, I am not adding/removing any properties from the entity classes. But how can I solve without touching backend? There is a chance of a deleted database happen. Can u help me here ?

Yes you can do that just choose code first approach in Entity framework and when have to edit some entity create the class and dbset and in package console manager enable the migration.
