This is actually very simple to put in place and will save you (and me) many headaches in the future.
First, execute these two commands in your Package Manager Console:
Add-Migration InitialMigration -IgnoreChanges
The first one will create a Migrations folder with a Configuration class (that enables the Automatic Migrations).
The second command creates an empty migration so that the future migrations will start from the current state of your database.
Additionally, I needed to add the following line in OnModelCreating method of my DbContext class:
Database.SetInitializer(new MigrateDatabaseToLatestVersion<WeekPlanDataContext, Configuration>());
That’s it! Now, If I add a new column in a model, it will be automatically added to the database schema. Even better than migrations in rails
