title: Entity Framework Code First Create Database
body: <p>I am new to Entity Framework.
  I want to make it Database as a separate Entity In project.
  So I started my project with as Class Library project.
  Starting with Login so class created for it with inherit IdentityUser.</p>
  
  <pre><code>public class ApplicationUser : IdentityUser
  {
      [Required]
      [MaxLength(200)]
      public string FirstName { get; set; }
      [Required]
      [MaxLength(500)]
      public string LastName { get; set; }
  }
  </code></pre>
  
  <p>Now I want to create database , I have added key in App.Config.</p>
  
  <pre><code>public class AppDBContext : DbContext
  {
      public AppDBContext():base("AppDBConnectionString")
      {
  
      }
  }
  </code></pre>
  
  <p>Any Package Manager command to create database for first time ?
  Update-Database didnt work.</p>
