I am trying to create a SPA model which is able to create, update, delete scheduled tasks in Visual Studio 2012 using MVC4 Hottowel SPA template. Here i have a demo class which I need to use in creating database but unable to get 1) the context of the database.
2) how to configure the database in this project. I tried with creating connection using (LocalDb)\v11.0 sql server but its showing error that entity framework 6 or above is not supported with this application.

public class JobDemo
    {
      public string JobName { get; set; }
      public string JobDescription { get; set; }
      public string Frequency { get; set; }
      public bool JobStatus { get; set; }
      public bool JobIsActive { get; set; }
      public DateTime LastModifiedOn { get; set; }
    }

This is my class which I wanna use to create database of scheduled tasks/jobs and then query on them

public class DemoDb : DbContext
    {
      public DbSet<JobDemo> Jobject { get; set; }
    
    }

The class is creating the DbContext of my JobDemo Class. But after that i am unable to create database connection which use my class and use the following attributes defined in my JobDemo class.
