EF 5 Enable-Migrations : No context type was found in the assembly

Question

I have 4 projects :

Toombu.Entities : all models are there
Toombu.DataAccess: Mapping, Repository and ToombuContext
Toombu.Logique : Logic of my application         


        

Answer 1

I created a Class in the Models directory called: myData with the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;

namespace Vidly.Models
{
    public class MyDbContext : DbContext
    {
        public MyDbContext()
        {
        }
    }
}

rebuilt the app with: control-shift-b

then ran the following in the nuGet Console:

Enable-Migrations -StartUpProjectName Vidly -ContextTypeName Vidly.Models.MyDbContext -Verbose

the Console returned:

Using StartUp project 'Vidly'. Using NuGet project 'Vidly'. Checking if the context targets an existing database... Code First Migrations enabled for project Vidly. Enable-Migrations -StartUpProjectName Vidly -ContextTypeName Vidly.Models.myData -Verbose

And the FrameWork created a Migrations directory and wrote a Configuration.cs template in there with the following code:

namespace Vidly.Migrations
{
    using System;
    using System.Data.Entity;
    using System.Data.Entity.Migrations;
    using System.Linq;

    internal sealed class Configuration : DbMigrationsConfiguration
    {
        public Configuration()
        {
            AutomaticMigrationsEnabled = false;
        }

        protected override void Seed(Vidly.Models.MyDbContext context)
        {
            //  This method will be called after migrating to the latest version.

            //  You can use the DbSet.AddOrUpdate() helper extension method 
            //  to avoid creating duplicate seed data.
        }
    }
}
