ASP.NET MVC : Context type not found in assembly

Question

This is my first asp.net mvc project. I used EF code first approach and created a separate class library to write my model and context. I also referenced the class library in mvc project. But now after creating few more new models when I try to enable migration, it gives me an error. I also tried all the possible solutions mentioned here : No context type found in the assembly. ASP.NET MVC4

Still problem remains the same. Am I missing something?

This is code for Context Class:

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.Entity.ModelConfiguration.Conventions;
using FYPPharmAssistant.Domain.Models;


namespace FYPPharmAssistant.Domain.DAL
{
    public class MyContext : DbContext
    {
        public MyContext()
            : base("MyConnectionString")
        {

        }
        public DbSet<GenericName> GenericNames { get; set; }
        public DbSet<Item> Items { get; set; }
        public DbSet<Manufacturer> Manufacturers { get; set; }
        public DbSet<Stock> Stocks { get; set; }
        public DbSet<PaymentStatus> PaymentStatus { get; set; }
        public DbSet<Purchase> Purchase { get; set; }
        public DbSet<PurchaseItem> PurchaseItems { get; set; }
        public DbSet<Supplier> Suppliers { get; set; }

        //avoids pluralizing table names
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        }
    }
}

And my web.config:

<?xml version="1.0" encoding="utf-8"?>

Did you try changing the name="MyConnectionString" to name="MyContext" in your web.config? — DDiVita

prntscr.com/89xplq are you executing the migration enable on the right project? btw by the message displayed in the second try i think the correct way to do that would be enable-migrations -ContextTypeName Domain.Dal.MyContext — Diogo Cunha

Taher Rahgooy . Thanks man ! You indirectly hit the point !! Yes, web.config belongs to FYPPharmAssistant. But all my entities is in another class library(FYPPrharmacyAssistant.Domain). I just changed the Default Project to FYPPrharmacyAssistant.Domain from the dropdown list in PackageManager Console and It worked. Thank you ! — Avishekh Bharati

This might be helpful for someone in future. So I am writing it again.

I just changed the Default Project to FYPPharmacyAssistant.Domain from the dropdown list in PackageManager Console and the problem is solved. FYPPharmacyAssistant.Domain is my seperate project or class library consisting of all my entities and database context class.

Context needs to be in the same project as your migration configuration
