Entity Framework 6 Migrations for ASP.NET 5

Entity Framework 6 Migrations for ASP.NET 5

1. Include the myget feed for this package, https://www.myget.org/F/atquin, or in global.json add the src directory of this repo to your projects list.
2. Reference Atquin.EntityFramework.Migrations in your DataContext xproj;

   "dependencies": {
   	"EntityFramework6.Npgsql": "3.0.3", <!-- if you want npgsql -->
   	"Atquin.EntityFramework.Migrations": "1.0.0-rc1-final"
   },
       "commands": {
   	"ef": "Atquin.EntityFramework.Migrations"
   }

2. If you don't have already, add a DataContextFactory that will create a DataContext using your config.json's connection string;

   public class MyContextFactory : IDbContextFactory<MyDataContext>
   {
       private IConfiguration _config;

       public MyContextFactory()
       {
           _config = new ConfigurationBuilder().AddJsonFile("config.json").Build();
       }

       public MyDataContext Create()
       {
           return new MyDataContext(_config["Data:DefaultConnection:ConnectionString"]);
       }
   }

4. Add a configuration to Migrate/Seed data;

namespace MyProject.Data.Migrations
{
       internal sealed class Configuration : DbMigrationsConfiguration<MyDataContext>
       {
           public Configuration()
           {
               AutomaticMigrationsEnabled = false;
               MigrationsDirectory = "Migrations"; // should match the end of your Namespace above
           }

           protected override void Seed(MyDataContext context)
           {
               Console.WriteLine("Executing seed...");
               ...
           }
       }
}

2. Open command prompt and execute the following;

cd /your/datacontext/directory
dnx ef add MigrationName

3. VS2015 will then immediately generate a same-named *.cs for the *.resx file created. Delete that *.cs file.
4. Now you can update the database;

dnx ef update

See the options below. Example;

dnx ef update -c "Data Source=myServerAddress;
