How can I disable code first migrations

Question

I have a code-first entity model in EF5. But I want to manage the database changes manually -- I do not want EF to modify my existing database and all its data. But when I make parallel changes in the EF mapping and in the database, EF refuses to operate properly telling me I need to use code first migration. How do I turn this off?

Answer 1

set the Database.SetInitializer to null.

public class DatabaseContext: DbContext {     //the base accepts the name of the connection string provided in the web.config as a parameter     public DatabaseContext()         : base("DatabaseContext")     {         //disable initializer         Database.SetInitializer<DatabaseContext>(null);     } 

Answer 2

So the most complete answer that I have found is this:

1. Delete Migrations folder inside your project.
2. Set Database.SetInitializer<DatabaseContext>(null); inside your DatabaseContext initializer.
3. Delete the table __MigrationHistory inside your database. For EF6+ the table is located under Tables but for earlier versions it is located under System Tables.
4. Build and run.
5. Profit.
