Entity Framework Entity-framework Code First Migrations Enable Migrations
Example
To enable Code First Migrations in entity framework, use the command
Enable-Migrations
on the Package Manager Console.
You need to have a valid DbContext implementation containing your database objects managed by EF. In this example the database context will contain to objects BlogPost and Author:
internal class DatabaseContext: DbContext
{
public DbSet<Author> Authors { get; set; }
public DbSet<BlogPost> BlogPosts { get; set; }
}
After executing the command, the following output should appear:
PM> Enable-Migrations
Checking if the context targets an existing database...
Code First Migrations enabled for project <YourProjectName>.
PM>
In addition, a new folder Migrations should appear with a single file Configuration.cs inside:
The next step would be to create your first database migration script which will create the initial database (see next example).
