Answer 1

Follow the below steps to resolve the issue

Install-Package EntityFramework-IncludePrerelease

or Install entity framework from Nuget Package Manager

Restart visual studio

After that I was getting "No context type was found in assembly"

To resolve it - This "No context" that mean you need to create class in "Model" folder in your app with suffix like DbContext ... like this AppDbContext. There you need to include some library using System.Data.Entity;

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


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

After that run the below command on Package Manager:

Enable-Migrations -ProjectName  -ContextTypeName 

My Project Name is - MyFirstApp and AppDbContext is inside the Model Folder so path is like

Enable-Migrations -StartUpProjectName MyFirstApp -ContextTypeName MyFirstApp.Models.AppDbContext
