Use context.Database.Migrate()
You can call this from your Startup class:
using (var context = new MyContext(...))
{
context.Database.Migrate();
}
It will migrate your database to the latest version on application startup. But be careful doing it, maybe comment out this code and uncommend only when you want to run your migrations.
