There was an error running the selected generator . try rebuilding the project

When I create the Scaffold and add the Model class then I am getting these error "There was an error running the selected generator . try rebuilding the project"

I have three Model class :

1.Department.CS

2.Designation.cs

3.CompanyDBContext.cs

Database : I have two table in database, 1. Department(deptID,deptName,Description)
2. Designation(desgtID,desgName,description)

Objective :- I want to create one view page for these scenario. Like this

Insert Name of Form (TextBox) + Department Name (Dropdown list box) + Designation Name (Dropdown list box)

1.Department.CS

namespace mvcAppraisalSystem.Models
{
public class Department
{
[Key]
public int deptID { get; set; }
public string deptName { get; set; }
public string Description { get; set; }
}
}


2.Designation.cs

namespace mvcAppraisalSystem.Models
{
public class Designation
{
[Key]
public int desgID { get; set; }
public string desgName { get; set; }
public string description { get; set; }
}
}


3.CompanyDBContext.cs

namespace mvcAppraisalSystem.Models
{
public class CompanyDBContext : DbContext
{
public DbSet<CompanyDBContext> Departments { get; set; }

public DbSet<CompanyDBContext> Designations { get; set; }
}
}

Answer

This is the problem with the connection string you can change the connection string with your DbContext name like bellow on the file web.config:

<connectionStrings>
  <add name="MovieDBContext" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\aspnet-MVCmove-20140616082808.mdf;Initial Catalog=aspnet-MVCmove-20140616082808;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

For the class:

using System;
using System.Data.Entity;
namespace MVCmove.Models
{
  public class Movie
  {
    public int ID { get; set; }
    public string Title { get; set; }
    public DateTime ReleaseDate { get; set; }
    public string Default1Genre { get; set; }
    public decimal Price { get; set; }
  }
  public class MovieDBContext : DbContext
  {    
    public DbSet<Movie> Movies { get; set; }
  }
}
